Interrogating Yourself on Your Computer Needs

If every computer owner had the same needs, only a single model would be available. But because today’s computers are used at home and at the office, for business and for pleasure, what works well for one person might not fit for another. [Paid Recommendations^^: Using photo recovery to recover your lost photos.] Although most computers sold at the time of this writing are Intel-based computers, they’re about as different from each other as the 30-odd flavors at your local ice cream parlor — or at least they should be.

To custom-build the computer that you need, you have to design it around who you are and what you plan to do. The easiest way to determine what type of computer you need is to ask yourself a series of questions. For those who enjoy TV shows about lawyers, here’s a chance to cross-examine yourself. Grab a pen and a notebook and write your answers to the questions on this checklist:

Primary application: What will be the main function of your computer? In other words, what will you be doing with it about 75 percent of the time
you’re using it? Do you plan to use the computer for word processing and drafting, or for Internet e-mail and Web surfing? Are you a big-time game
player who likes to play the latest and hottest 3-D game releases? Jot down the main function of your computer under the heading “Primary application.”
If you’re not quite sure what your primary application will be, just write a general descriptor, such as Internet access, home use, or very expensive
paperweight. 
Secondary application: What will be the secondary function of your computer? In other words, what will you typically use it for if you’re not per-
forming the main function? Do you play games during the evening, or does your family use the computer for educational purposes or those hot eBay
bargains? Write the secondary use for your computer under the “Secondary application” heading. 
Family computer: Will children be using your computer for educational games? If so, write that use under the “Family computer” heading. 
High-quality video: Will you be using your computer for heavy-duty graphics, such as the latest cutting-edge 3-D games; professional desktop publishing; home DVD theater; video editing (say, with a program such as Adobe Premiere Pro); or advanced image editing (say, with a program such as
Corel Paint Shop Pro Photo X2)? [Paid Recommendations^^: Using Mac photo recovery to recover your lost photos.] If so, write required under the “High-quality video” heading. 
Power user: Are you going to run an entire suite of computer programs, such as Microsoft Office? Will you be running sophisticated, expensive
applications, such as Adobe Creative Suite 4? If you’re planning on using complex programs, write yes under the “Power User” heading.
Some people just plain want the fastest possible computer. They hate waiting, and they’re willing to pay extra to get the Cadillac of computers that’s
ready for anything. If you fit this description and you don’t mind paying extra for many of your computer components, go ahead and write yes under
the “Power user” heading. You’ll spend more money than the typical person because you’re buying more powerful and expensive parts, but you’ll probably end up with the nicest computer on your block — and your PC will last longer before requiring an upgrade. 
One last question: Where were you on the night of the 15th? (Too bad Perry Mason didn’t have a computer to keep track of all those details!)

See, that didn’t hurt! You’ve now eliminated the salesperson and built a list of your computer tasks and activities. From this list, you can build your own description of your computer needs. Pat yourself on the back and pour yourself another cup of coffee or grab another soda. In the following section, you use this list to determine what type of components you need to build into your computer.

Connecting Your Computer Components

[Paid Recommendations^^: Using Mac photo recovery to recover your lost photos.]

You might be wondering how to connect all the various components that make up a computer. “What happens if I connect something wrong? Am I going to light up like a Christmas tree? Will I burn up an expensive part?”I admit that when I built my first computer in the early 1990s, I had these same con-cerns. To reassure you, consider these facts:

  Most connectors for computer components are marked to help you plug them in correctly. In fact, some connectors are designed so that you can
install them in only one direction, with many using color to indicate where they connect.21 Chapter 1: A Screwdriver Is All You Need

  Ruining a computer component simply by plugging it in the wrong way is almost impossible. At the worst, the device simply won’t work. Just con-
nect the component properly, and it should work just fine.

  Although you connect your computer to a wall socket, unless you disassemble the power supply or monitor (which you are not going to do), you
won’t be exposed to dangerous voltage.

Of course, it pays to take basic precautions — such as unplugging your PC each time you add or remove a component.

Most components within a computer are connected with cables. For example, Figure 1-5 shows a power cable (a perfect illustration of a connector that can only work The Right Way). Of course, I give you instructions on how to make sure that you’re connecting cables properly.

You’ll also be adding adapter cards. [Paid Recommendations^^: Using photo recovery software to recover your lost photos.] These circuit boards plug into your computer, much like how a game cartridge plugs into a video game. Adapter cards provide your computer with additional features. For example, you can add a sound card to provide better audio than the built-in sound hardware that came with your motherboard. Adapter cards are arranged in rows at one end of a computer.

Depending on the type of motherboard that you install, you’ll use PCI, PCI-Express, or AGP adapter cards. In Chapter 3, I explain how to select the right type of adapter card as well as what all those NASA-inspired abbreviations mean. Make sure that you get the right kind of adapter card because the wrong type of card won’t fit.

The Data Warehouse, Bells and Whistles

The Data Warehouse
Earlier in this chapter, I mention that your RAM modules act as your computer’s memory while the computer is running. However, when you switch off your computer, it forgets the data in RAM, so you need a permanent place to store Uncle Milton’s Web page address or your latest stock report. This permanent storage comes in three forms: hard drive, removable storage drive (for example, a DVD/ Blu-ray recorder or a USB Flash drive), and (maybe) a floppy disk drive.

Some PCs still include one floppy drive. [Paid Recommendations^^: Using photo recovery software to recover your lost photos.] (You know the one. It still uses a 3 1 ⁄ 2 -inch disk that holds a paltry 1.44MB.) If you like, you can skip the installation of a floppy drive, seeing as they are as unnecessary as an appendix to a cutting-edge PC running Windows Vista. (A USB Flash drive is far superior in every way to the venerable floppy.)

You need at least one hard drive. Today’s hard drives hold gigabytes (GB) of data (that’s 1,000 megabytes), or even a terabyte (TB) of data (that’s 1,000 gigabytes). At the time of this writing, typical hard drives range in capacity from 80GB to more than 1TB — and those figures are constantly rising, while costs are constantly dropping. (You’ve gotta love that free-market competitive model!)

Buy as much data territory as possible.

The Bells and Whistles
Today’s multimedia PCs have almost more extras, add-ons, and fun doodads than any mere mortal can afford (well, except for Bill Gates, that is). If you want to be able to install and run today’s software, though, you need at least a DVD-ROM drive. Multimedia applications and games also need a sound card (or built-in audio hardware on your motherboard), along with a set of speakers or headphones.

Another common addition to a PC is a printer. [Paid Recommendations^^: Using Mac photo recovery to recover your lost photos.]If you need the lowdown on today’s printer technology, jump to Chapter 13. If a high-speed cable or DSL Internet con- nection is available in your area, you can jump on the Internet broadbandwagon. (That’s so bad it doesn’t even qualify as a pun.) Otherwise, you can still use a dial-up modem for connecting your computer to other computers across telephone lines, especially if you’re an Internet junkie.

In later chapters, I also discuss advanced stuff for power users, such as network hardware and scanners. You don’t have to read those chapters, and you won’t be tested on them. But they’re there in case you feel adventurous (or you really need them).
