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.
