WHAT IS HOME THEATER?
Do you dream of having a huge television screen with unhindered surround sound? Are you a TV buff, craving for improved quality in your system? Do you dream of watching cinema every day in your living room? Well, a Home Theater is the answer to all your dreams.
BUYING HOME-THEATRE COMPONENTS TV Screen: Well, first things first. You definitely need a large TV. Remember, the buzzword here is THEATRE! The size, resolution, and flatness etc of your TV will be of prime importance.
Speakers: Again, a good set of speakers, and I don't necessarily mean expensive, but carefully chosen speakers would give life to all your viewing.
HiFi VCR: The VCR is a relatively old technology and as a result, even the most feature-packed units are now very affordable. Make sure your VCR has HiFi stereo outputs in order to enjoy surround sound from a VHS tape. If you are buying a new VCR, you should also make sure it includes 4 video heads. 4-head VCR's provide cleaner looking slow motion play and freeze frames. It's a must have for a home theatre, you do want to record your favourite programmes to watch later don't you?
DVD Player: The world over, the DVD has brought the movies to your living room. A much better quality than VHS, digital technology also is better as it keeps away the fungus and no jhanjhat of tracking!
Satellite and Cable Broadcasts: A cable connection is good, but a Digital Satellite Broadcast can offer the most programming choices. However, you need to buy and keep, or lease the equipment. And unlike most cable programming, local TV stations are not available.
Audio/Video Receiver: Think of the A/V Receiver as the hub, which determines which source (CD player, Radio, DVD player, VCR, Tape Deck, etc.) will send the audio (and sometimes video) signal to the speakers and Television. There is no difference between an amplifier and receiver except that a receiver includes a tuner for listening to AM and FM stations. If the receiver includes a processor, then the audio signal can be "processed" to produce the surround sound experience.
Add-ons: Adding a Dolby amplifier to an existing stereo system easily converts it to a multi-channel home-theatre. Amplifiers are available right from 35 watts upto 100 watts RMS (per channel). Always match the amplifier with the speakers; an underpowered amplifier can damage the speakers. So, if you have 35 watts speakers, go in for a 35 watts amplifier.
Dolby ProLogic: Dolby Pro Logic separates a Dolby Surround Sound encoded stereo signal (two channels) into four separate channels- One for the Front Right, One for the Front Left, One for the Center, and one for the Rear (both rear speakers get the same signal). While Dolby ProLogic does not provide a separate channel for Low Frequency Effects (LFE), a powered subwoofer can, and should, still be added for separate amplification of the bass frequencies.
Dolby Digital and DTS: Dolby Digital and DTS includes 6 separate audio channels. Five of these signals carry the full range of frequencies audible to the human ear (Front Right, Front Left, Center, Right Surround, Left Surround) and one signal carries only low end, or bass frequencies for special effects. Basically, the DTS is just a better, fuller sound. It gets better and better…
You can either buy HtiB (Home theatres in a Box), which includes all the components together (amplifier, speakers, subwoofer etc) or buy them separately. The second option will cost you more, but gives a better sound output, flexibility to choose according to your choice and also gives the option of upgrading later on.
HOME THEATRE ARRANGEMENT
SPEAKERSHow you place your speakers can determine whether they will work at their best or not. Each speaker in a home theatre system has its own, unique feature.
Left, Right They carry primarily music and sound effects, and should have the same wide, smooth response as good stereo speakers.
CentreThe centre speaker carries much of the dialogue as well as music and effects, so ideally should be identical to the left and right speakers. A smaller speaker can be used, however, thanks to the "Normal" mode that feeds center channel low bass to the left and right speaker (B). You can even do without one.
SurroundSurround speakers need not reproduce low bass, so can be small and inconspicuous. Nevertheless, their overall sound balance should be as close as possible to the front speakers. Proper placement is vital to establish an evenly distributed sound field.
SubwooferA true subwoofer designed to reproduce powerful low bass effects (explosions, the rumble of spaceships, etc.) dramatically heightens involvement with the action on the screen. Some models are powered by built-in amplifiers, while others are designed to be driven by your existing amplifier, or, for better results, by a separate bass amp. It is not necessary that the subwoofer is of the same make as the speakers, but it should be of the same quality.
Magnectic ShieldingSpeakers placed less than two feet from the TV set must be magnetically shielded models to prevent picture distortion. Virtually all speakers designed specifically for center channel use are shielded, as are many other "A/V" models.
Add-on SpeakersCenter and surround models from virtually all speaker manufacturers make it easy to convert an existing stereo system to home theatre.
In-wall SpeakersMany speaker manufacturers offer high-quality in-wall systems that effectively "disappear" in the room. All five speakers can be in-wall units, or just the fronts or surrounds.
Satellite SystemsMany speaker manufacturers offer high-quality in-wall systems that effectively "disappear" in the room. All five speakers can be in-wall units, or just the fronts or surrounds.
AlignmentAlign the center speaker evenly with (A), or slightly behind (B), the left and right speakers, but not ahead of them.
AnglePlacing the left and right speakers to form a 45 degree angle with your favorite viewing position will duplicate the soundtrack mixer's perspective.
HeightThe mid- and high-frequency drivers of the three front speakers should be as close as possible to the same height. This often requires placing the center speaker directly atop (A) or beneath (B) the TV set.
SURROUND SPEAKERS PLACEMENT
Place the systems preferably on the sides of the system.
HeightIf space permits, install surrounds 2-3 feet above viewers. This helps to minimize localization effects.
AimingAiming surrounds straight across the room, not down at viewers, helps create a more open, spacious surround soundfield. (Some models may require different aiming; see Special designs below).
Special DesignsSidewall mounting, while preferred for direct radiating speakers (A), is usually required for surround speakers designed to radiate to both the front and rear (B). Check instructions for any special placement or aiming needs for your speakers.
TELEVISION PLACEMENT
The TV should not be too close to where you sit. Apart from the fact that you will strain your neck, the screen will also look grainy. A general rule of thumb is to place the television 3 times the screen's diagonal dimension from the ideal viewing and listening spot. As an example, for a 35" TV, your eyes should be 105" (35 x 3), or about 9 feet away. Flat screen TV's minimize glare from light sources in the room. For all other TV's, the natural bow of the screen will pick up light sources throughout the room. Thus don't place lamps etc in a way that the TV catches their glare.
INSTALLATION AND OPERATION TIPS A do-it yourself guide:
The room:
Too many bare surfaces can cause reflections that add harshness to the sound or muddy the dialogue; carpeting and drapes help to keep them in check.
If you have a choice of rooms, avoid those that are perfectly square, or that have one dimension exactly twice another; they can aggravate resonances that colour the sound.
Center the seating area between the side-walls on which you mount the surround speakers.
Keep out external noise by sound proofing the room to enhance the listening experience.
The closer a speaker is placed to intersecting room surfaces--corner, wall and ceiling, wall and floor--the stronger its bass output (possibly too strong in some cases).
Amplifier power: All three front channels should have the same power if the three front speakers are identical. With a smaller center speaker, less center channel power is required. A total of one-half the power of one main front channel is usually sufficient for the surrounds. Specific power requirements depend on how loud you listen, speaker sensitivity, size of the room, and how much its furnishings "soak up" sound.
Audio/video connections: Use good-quality shielded cables, and be sure plugs are fully inserted into jacks. Follow the color code used on most connectors and cables to prevent confusion.
Speaker wiring: Prepare speaker wires by stripping their ends (A), then twisting the bared strands tightly together (B) to prevent shorts across terminals (C). Or, if speaker and amplifier/receiver terminals permit, use "banana" plugs to ensure solid connections (D).
Speaker polarity: Connect the "+" and "-" (usually red and black) terminals on each amplifier channel to the corresponding terminals on each speaker. To make this easier, speaker cable is coded with a bead or stripe down one lead's insulation, and/or different colored wires. Connected identically, all speakers will operate "in phase," with their cones moving back and forth together. "Out of phase" connections, while doing no harm, muddy spatial effects and weaken bass.
Processing enhancements: Some systems also feature "Cinema" digital signal processing (DSP) modes that simulate the acoustics of large theaters, and/or "THX(r)" processing that also strives for a more "theatrical" experience. These are provided as enhancements to Pro Logic decoding, not as alternatives.
Channel balance: Systems with Dolby Pro Logic decoding feature a test signal generator for balancing the channels. As the signal "travels" from channel to channel, adjust the balance controls until each channel plays at the same loudness level. SOME COMMON MISTAKES
Subwoofers and surround speakers are too loud: Enjoy the quality sound, don't overdo it. Calibrate them with a SPL meter and a noise source. You don't want your neighbours to call the police do you?
TV's set to the cool colour temperature: The "warm" setting on most TV's is much closer to the 6500 degrees K level that most people consider "standard". So set it to "warm" or ask someone to calibrate your TV.
Surrounds blasting in the ears: The surround speakers should be higher up and farther away. You don't want to be easily distracted by surround effects. Envelopement should be the goal.
Turn the sharpness on your TV down: Sharpness is bad, it causes ringing, and in excess it actually lowers the resolution instead of increasing it. Keep it at a comfortable level.
Too much ambient light washes out the picture:Close the drapes and turn off the lights, make it dark. I mean, if you want a theatre experience, why leave the lights on?
Bad room layout symmetry:Not having the TV centered or having the front speakers all akimbo is a very common mistake. Putting the TV in the corner is bad. Putting the left front speaker on the floor and the right front on top of the bookshelf is bad. Putting those satellite sized surround speakers on the floor behind the plant is bad. Most of us can't have a dedicated movie room, usually a room needs to maintain its multifunctional value. But hey, that doesn't mean you strain your neck to watch the TV.
Your home theatre system is supposed to be an experience for you to enjoy the experience, and not to ruin it for others. Too much sound is bad, go for quality sound not noise. Enjoy the experience.

Do we need pizza at someone's cost?
Do we need pizza at someone's cost??? Read it & answer urself…
Recently in The Times of India there was an article / advertisement about Pizza delivery Companies which guarantees you free pizza if they fail to deliver within the specified time (like 30 minutes). Have you ever wondered who pays for the free pizzas?? Well, the delivery boy is made to pay for the pizza. They are paid such low wages and the price of the pizza is deducted from their monthly wages which can amount to upto 60% in some months (It becomes difficult to run their family). To deliver the pizzas the delivery boys take high traffic risks as delivery becomes their priority. Their life and safety risks are neither looked into by the Pizza Shop Management nor the Pizza Delivery Boy himself. (They are more concerned to avoid the deduction from their salary).
If this type of exploitation is carried on in your city's pizza logistics we should stop availing the home delivery system, because to deliver our pizza one person may be risking his life. Is the life of an Indian citizen so cheap and of no value?
In case he is late in delivering the pizza, we are enjoying the free pizza at the hard earned money of a poor delivery boy. Is it fair or right on our part to do it?
As a human, please think and if you feel that this is wrong, please spread the message and stop having pizzas delivered at home .

Why is every election a warning bell?
Has democracy failed in India?
Put that bluntly,
the answer has to be `No'.
Anarchical sure, but our democracy is still functioning. The problem is that it has developed a dangerously brittle, touch-and-go character. It has become, shall we say, failable.
The usual "estates" that sustain democracy have failed. The Executive was the first to collapse with corruption and criminality overrunning it. Parliament has become negative with parties mistaking House stalling for patriotism. The traditional First Estate is God. Even that has lost out with god-men taking the place of gods. The Fourth Estate of course has lost its credibility.
If the system still remains functional, it is because of the judiciary which is by and large intact and the Election Commission which guards its independence. The power and dependability of both were on show last week.
Consider Shibu Soren, a thug who should never have been in politics let alone in the Central Cabinet. What a commentary on Indian democracy that one of the cleanest prime ministers we have ever had is forced to take into the Cabinet this man who killed his own personal secretary; Mohammed Taslimuddin accused of murder, robbery and extortion; Ali Ashraf Fatmi charged with kidnapping and extortion; Jaiprakash Narain Yadav, of fake duplicate certificate fame; and Laloo Prasad himself.
The judiciary's best gift to democracy was the ruling that "sanction" was not necessary to prosecute public servants for corruption. For too long crooked politicians and civil servants have taken refuge under the sanction provision. Their excuse was that they were carrying out public duties and should not be obstructed in such duties.
Which of course is nonsense.
The Supreme Court has said once and for all that taking bribes is not duty. The Election Commission made its own contribution to democracy by handling this week's critical byelections with exemplary efficiency. It could not of course control the results.
Eventually deserving candidates won, but that was small consolation. In Karimnagar the Telangana flag flew high giving Chandrasekhar Rao a two-lakh plus margin. In Chamundeshwari and Thiruvambadi cliff-hanger drama ruled the roost, with the victor's margin at 257 and 246.
The future turns dark when we see how successfully Karnataka politicians ensured that every single vote was cast along caste lines. The wafer-thin difference the loser achieved through reckless caste play suggests that the same caste politics will be used to dominate elections from now on. In Kerala the tradition of incumbent governments ignoring people's interests continues. The LDF now in power is so obsessed with internal one upmanship that governance goes by default. Neither it nor the Congress-led UDF has any issue to debate. So everyone resorted to Christian-Muslim communalism with abandon.
Clearly, casteism is rapidly becoming the foundation of our electoral democracy. The seed of casteism was sown when we enshrined linguism with the linguistic reorganisation of states. Linguistic-regional bigotry and religious-caste bigotry are two sides of the same coin. Hence the link between Chandrasekhar Rao's Telangana party and Deve Gowda's JD(S). If our voters are taught to vote only by dialect, religion, caste and subcaste, then finally the devil will have taken over our democracy.
The failable will then finally fail.

SC/ST Reservation: Are we democratic.
SC/ST Reservation: Are we democratic.
The SC/ST reservation nothing more than the individual interests of the politicians before the elections. The MANDAL-II( Reservation in educational institutions), again there could be self immolation cases in protesting against the reservation, atleast the government should learn from the past (1978). Reservation should be on the basis of economic level of the studnet's family.
The protest should gain momentum in every part of india. More and more awareness should be generated among the masses through SMS, Blogs, Emails. Everbody or atleast somebody has to take the initiative and knock the doors of the government. Are we democratic, if so we have to make sure the government takes its decision back. Nearly 50% SC/ST reservation; I mean, What is this!!!
Our History tells the people of United India together can change the things, it seems to be difficult but we can make the things happen in our favour. Don't you people think!
Media is the most important medium to convey this message take the decision back. Remember Rang De Basanti. Walk to government they will take back the decision.

HOW PROCESSER WORKS
HOW PROCESSER WORKSIf you've been reading Ars for a while then you know that we don't normally do generalized overview articles. Most of our articles deal with specific technologies and products. However, the success of my recent article on bandwidth and latency, which was in fact a general overview, got me thinking that perhaps the time was right to do an overview of a topic that I write on quite often: microprocessor technology. This article, which is the first in a series, is aimed at providing the reader with the kind of background that he or she needs to understand the CPU technology coverage on Ars and on other sites. And with Itanium2, Yamhill, AMD's Hammer, and other new chips on the horizon, there's quite a bit of such coverage coming up. Here's a quote from the article that should give you a taste for the level at which it's written.Since the numbers must first be fetched from storage before they can be added, we want our storage space to be as fast as possible so that the operation can be carried out quickly. Since the ALU is the part of the processor that does the actual addition, we'd like to place the storage as close to it as possible so that the operands can be read almost instantaneously. However, practical considerations, such as a modern CPU's limited die space, constrain the size of the storage area that we can stick next to the ALU. This means that in real life, most computers have a relatively small number of very fast storage locations attached to the ALU. These storage locations are called registers, and the first x86 computers only had 8 of them to work with. These registers store only a small subset of the data that the computer is currently working with.Although the article is fairly basic, I suspect that more advanced readers will also benefit from it. I know that it was quite helpful for me to go back and think about this material at a more abstract, conceptual level. In writing this article, I sort of felt like I was building large boxes in which to put all of the things I've learned over the yea
What to look for in an assembled PC
1) Motherboard
The large circuit board into which the Central Processing Unit, memory boards and peripheral cards are plugged is referred to as the motherboard.
It is the most vital part of any computer as it holds and connects all your peripherals and add-ons to give you upgrade options and support for future technologies.
What you must know:
Check whether it comes with all the necessary options, support for upgradeability and extra slots for memory and other add-on cards.
2) Processor
Processor chips are primarily available in two brands -- INTEL and AMD.
The Intel chips range from the very basic Celeron chip to the Pentium series to the advanced Centrino processor.
AMD has a chip called Athlon, which is slightly cheaper than the higher end Intel chips.
Most users prefer Intel Pentium chips to Athlon as the latter heats up soon and isn't as efficient as a Pentium 4 chip. Also, the Athlon chip based systems need extra fans to cool the system.
The most preferred chip is the Pentium 4 2.4 GHz.
You might want to consider the Athlon chip with the motherboard would cost you about $70 less than its INTEL counterpart.
What you must know:
Though the processor speed plays a crucial role, you need not have the latest and fastest one available. If a processor with a slightly lesser core speed can do just as well for your demands, go for it. Make sure the chips are box packed with a serial number to ensure they are original.
3) Random Access Memory
RAM is the amount of memory available for use by programmes on a computer.
The RAM chip comes in capacities of 128, 256, 512 MB, even 1 GB. Most computers function efficiently with 256 MB RAM, though a 512 MB RAM does offer you an edge.
As a thumb rule, always go in for a minimum of 256 MB RAM.
The cost difference between 256 MB and 512 MB is around $30.
The latest memory technologies in use are DDR RAM, RD RAM and the latest release of the DDR2 RAM.
What you must know:
Since it ensures the smooth running of your system, the more the better. Make sure the memory capacity is upgradeable. Make sure the RAM is original and opt for the DDR range of RAMs. Duplicate RAMs will not function on Windows XP operating systems.The RAM comes with a year's warranty.
4) Hard Disk Drive
HDD capacity counts for a great deal.
A 40 GB hard disk is sufficient disk space but you may choose an 80 GB variant.
The brand SEAGATE is a very reliable brand for hard disks and is preferred by most computer manufacturers and assemblers.
What you must know:
The hard disk comes with a three-year warranty.
5)Monitor
Monitors are computer screens available in varied sizes, the most popular being the 15" and 17".
You can choose between a flat panel plasma screen and a regular desktop monitor.
A 15" monitor costs around $100 and the 17", between $150 and $200, depending on the type.
The Dynaflat type monitor is preferred to the conventional CRT type, which is technically referred to as the Cathode Ray Tube.
The plasma screen monitor is highly priced at about $400 plus.
The various brands for monitors are Samsung, Mercury and LG, to name a few. Samsung is the preferred alternative for monitors and is also the leading peripheral components dealer.
What you must know:
Monitors usually come with a three-year warranty.
6) Peripherals
These include the keyboard, mouse, web cam, printer, scanner, joystick, etc.
Samsung and Microsoft are the preferred brands.
Choose an optical mouse over the usual one. The price difference is marginal. The same applies for the Internet keyboard.
Don't opt for a wireless mouse or a keyboard as the sensors get spoilt with time. Besides, you have to charge the batteries every week.
Web cams can cost from anywhere between $20 and $100.
For printers and scanners, Hewlett Packard is the market leader. A domestic colour printer might cost around $100, though the cartridges are a tad expensive at $40 each.
What you must know:
Don't choose the cheapest printer in sight. You will spend the money you save in less than a year on cartridges.Don't go for the ones cheaper than $30 as they have poor resolution.
Voltage stabilisers and Spike guards
If your locality has frequent power failures or severe voltage fluctuations, opt for a voltage stabiliser. This will prevent any damage that could reduce the life of your machine.
A voltage stabiliser can cost from $20 to $40.
Regardless of the locality and the power supply, opt for a spike guard. It will provide four power plug points for your computer and peripherals.
A spike guard is also called a transient suppressor. It will cost $20.
The large circuit board into which the Central Processing Unit, memory boards and peripheral cards are plugged is referred to as the motherboard.
It is the most vital part of any computer as it holds and connects all your peripherals and add-ons to give you upgrade options and support for future technologies.
What you must know:
Check whether it comes with all the necessary options, support for upgradeability and extra slots for memory and other add-on cards.

Though the processor speed plays a crucial role, you need not have the latest and fastest one available. If a processor with a slightly lesser core speed can do just as well for your demands, go for it. Make sure the chips are box packed with a serial number to ensure they are original.
3) Random Access Memory
RAM is the amount of memory available for use by programmes on a computer.
The RAM chip comes in capacities of 128, 256, 512 MB, even 1 GB. Most computers function efficiently with 256 MB RAM, though a 512 MB RAM does offer you an edge.
As a thumb rule, always go in for a minimum of 256 MB RAM.
The cost difference between 256 MB and 512 MB is around $30.
The latest memory technologies in use are DDR RAM, RD RAM and the latest release of the DDR2 RAM.
What you must know:
Since it ensures the smooth running of your system, the more the better. Make sure the memory capacity is upgradeable. Make sure the RAM is original and opt for the DDR range of RAMs. Duplicate RAMs will not function on Windows XP operating systems.The RAM comes with a year's warranty.
4) Hard Disk Drive
HDD capacity counts for a great deal.
A 40 GB hard disk is sufficient disk space but you may choose an 80 GB variant.
The brand SEAGATE is a very reliable brand for hard disks and is preferred by most computer manufacturers and assemblers.
What you must know:
The hard disk comes with a three-year warranty.
5)Monitor
Monitors are computer screens available in varied sizes, the most popular being the 15" and 17".
You can choose between a flat panel plasma screen and a regular desktop monitor.
A 15" monitor costs around $100 and the 17", between $150 and $200, depending on the type.
The Dynaflat type monitor is preferred to the conventional CRT type, which is technically referred to as the Cathode Ray Tube.
The plasma screen monitor is highly priced at about $400 plus.
The various brands for monitors are Samsung, Mercury and LG, to name a few. Samsung is the preferred alternative for monitors and is also the leading peripheral components dealer.
What you must know:
Monitors usually come with a three-year warranty.
6) Peripherals
These include the keyboard, mouse, web cam, printer, scanner, joystick, etc.
Samsung and Microsoft are the preferred brands.
Choose an optical mouse over the usual one. The price difference is marginal. The same applies for the Internet keyboard.
Don't opt for a wireless mouse or a keyboard as the sensors get spoilt with time. Besides, you have to charge the batteries every week.
Web cams can cost from anywhere between $20 and $100.
For printers and scanners, Hewlett Packard is the market leader. A domestic colour printer might cost around $100, though the cartridges are a tad expensive at $40 each.
What you must know:
Don't choose the cheapest printer in sight. You will spend the money you save in less than a year on cartridges.Don't go for the ones cheaper than $30 as they have poor resolution.
Voltage stabilisers and Spike guards
If your locality has frequent power failures or severe voltage fluctuations, opt for a voltage stabiliser. This will prevent any damage that could reduce the life of your machine.
A voltage stabiliser can cost from $20 to $40.
Regardless of the locality and the power supply, opt for a spike guard. It will provide four power plug points for your computer and peripherals.
A spike guard is also called a transient suppressor. It will cost $20.
HAREWARE TIPS FOR ALL KIND OF USERS
HAREWARE TIPS FOR ALL KIND OF USERS
This week I have more of my special tips and tricks, this time concentrating on hardware tips for all computer users.
1. Get rid of bad vibes. Put your computer where it won't be subject to vibration, shaking or accidental kicks. They can mess up your hard drive. If it's on top of your desk, make sure your desk can't rock (even slightly) from side to side or front to back; prop up any short legs if you need to. If it's on the floor, make a solid platform out of concrete blocks covered by a velvet cloth or an old sheet, whichever looks better.
2. Keep it cool. Don't cut off the flow of air to your computer. Depending on the design, your computer draws air in through vents in the front, sides or bottom. Keep everything at least an inch away from obvious vents. (Bonus tip: If your computer starts running hot, don't take off the case in an attempt to give it more airflow. That usually diffuses the air too much. Instead, find out why it's running hot and get it fixed.)
3. Save electricity. Modern computers are able to hibernate (go into deep sleep) after a period of inactivity. Look for a setting (in the Control Panel or in the computer's System Preferences) for power-saving adjustments. Hibernation is a good idea for families who use an always-on Internet connection, too, because it takes computers offline and thereby shields them from intruders.
4. Kill the old mouse. The best kind of mouse uses a red light beam and has no moving parts. Optical mice, as these designs are called, can't get messed up by dirt and cat fur. Do yourself a favor and replace the old gummy-ball critter with one that can't get cruddy. (Bonus tip: Just plug the new mouse in and forget the installation software that comes with it. You don't need it.)
5. Take the bus. If your computer uses more than two USB devices, buy a powered USB bus to take the load off your computer. Plug the first device into your computer and the others into the bus. Be sure it's a powered bus; non-powered ones simply add more of a drain.

Before Buying New Computer ?
1. Why do you need a computer?
Whether you are a new user or advanced one, whether this is your first computer or second (or even third), be clear as to why you want a computer before you even think of buying one.
How will you use your computer? Are you only interested in browsing the Internet and checking e-mail? Do you plan to use your PC as a programming machine? Do desktop publishing or video editing feature on your agenda? Or is it a gaming rig?
Consider these factors before stepping into a hardware shop.
The basic components of a computer system are the motherboard (containing the processor and memory), keyboard, mouse, monitor, diskette drive, CD-ROM drive and hard drive.
In addition, there are several other types of devices you may or may not need. A trackball, joy stick, modem, tape drive, zip drive, printer, plotter, scanner, sound card and speakers, television card and video capture card, to name a few.
Whether you buy these will depend on what you need the computer for and which software applications you intend to use.
Remember the golden rule: the fastest or most expensive computer is not necessarily the one you need.
Finally, the length of time that you plan to own the computer before replacing it will also help determine which computer to buy.
2. What is your budget?
This is the next thing you need to be certain of. How much are you willing to spend on a PC?
After you arrive at a figure, keep a margin of a few thousands. It will give you some room for flexibility. If you are short on money when you buy your computer and cannot add all the peripherals you want, be smart.
Buy as much as you can afford. Don't cut corners on the main system unit (monitor, processor, memory, disk space).
Remember, you want the computer to last at least four years. You don't want to run out of disk space or memory in the very first year, all because you trimmed down on the memory or got a smaller hard drive.
Hard disk capacity matters a great deal as it takes no time for data to fill the available space. A 40 GB hard disk is sufficient disk space, but 80 GB is the standard recommendation.
Random Access Memory is the amount of memory available for use by programmes on a computer. One of the important factors to ensure the smooth running of your system is the memory available.
The more the memory, the better it is. Make sure you can upgrade your computer's memory as and when required.
The RAM chip comes in capacities of 128, 256, 512 MB, even 1 GB. Most computers function efficiently with 256 MB RAM, though a 512 MB RAM does offer you an edge.
Hold off on the printer or a software application and other accessories that you really don't need right away. You shouldn't have any problem installing these after the original purchase has been made. Just ensure you buy components that are compatible with your system.
3. Should you go for a branded PC or an assembled one?
Assembled machines are popular because they are more economically priced.
Branded PCs cost around 35 to 40% more than their assembled counterparts.
Besides, you can choose your own specifications with assembled PCs. You are not forced to accept a rigid component configuration. You cannot customise a branded PC to suit your exact requirements.
With the same price that you would pay for a branded piece, you will be able to own a superior assembled PC.
Make sure the components purchased for the assembled PC are original. Take along an informed, reliable assembler to purchase the components so that you are not fooled by counterfeit parts.
The advantage of a branded PC is the reliability of the brand, the after sales service and the technical support. On the flip side, the after sales services and repairs offered by the brands are a tad expensive and not prompt most times.
Don't forget to look at the warranty. Generally, a warranty period of a year is normal for all major parts of the PC. But there are good brands that offer either more years or the option of an additional payment to top up the warranty period.
Talk to your friends and colleagues who have assembled PCs. Ask them about their experience and recommendations on whom to approach. Question them as to what happened when they had a problem. Was the individual easy to access? Did he offer prompt service? Does their computer give a lot of trouble?
If possible, meet two or three individuals before you finally zero in on one.
Spend some time on these three issues and you will be all set to buy your very own PC!
