Introducing the Major Parts of A Computer-1

Before you find out more about where to buy the parts that make up a computer, allow me to introduce you to each of the major components. I describe each component in general, although you can find out all the details about each computer part in other chapters of this book.

The metal mansion
Your computer’s case is its home, complete retrieve pictures with a power supply, the various buttons and lights on the front, and the all-important fans that keep the inside of your com-puter cool. Today’s high-power gaming machines have three or four fans, depending on how many devices inside are generating heat — heck, the fastest PCs that gamers build these days are liquid-cooled, just like your car!

You might notice several large, rectangular cutouts on the front of your case. Don’t worry — your computer case isn’t defective; it’s supposed to have them. These holes, called drive bays, enable you to add components, such as a DVD-ROM drive. An unused drive bay is usually covered by a plastic insert. Or the front of your case might have a door that swings open for access to the bays. Gamers and PC techno-jocks swear by unique cases, just like how owners of custom cars love fancy paint jobs and flames galore. This case has additional air vents at the front and room for more fans at the back, as well as colorful paint and chrome accents.

You can get computer cases in various sizes. The size that you choose depends on how many toys (usually called peripherals) you want to add to your computer.

The big kahuna
A number of different circuit boards are inside a recover deleted photos on Mac computer, but only one is big enough, complicated enough, and important enough to be called your computer’s motherboard. Your computer motherboard holds

  The CPU chip: This acts as the brain of your PC.
  The RAM modules: These act as your computer’s memory while it’s turned on.
  All sorts of connectors: You connect lots of things to your motherboard, such as hard drives, a DVD drive, and power cables.

In fact, the motherboard holds just about everything.

Tip:If you enjoy acronyms and abbreviations, you’ll be happy to know that CPU stands for central processing unit, and RAM stands for random access memory.

Computer CPUs come in different speeds, measured in gigahertz (GHz), such as 3 GHz. Sometimes, the CPU speed is mentioned after the processor name, such as Pentium 4 3.06 GHz. In general, the faster the CPU speed, the faster your computer.

The most popular brand of CPU these days is the Intel Core 2 series, which includes the Core 2 Duo and Core 2 Extreme Edition, but you can also find processors from Advanced Micro Devices, which everyone calls AMD. AMD’s alternative CPUs are usually less expensive and often run as fast and efficiently as the Core 2 series. I discuss the most popular processors and their advantages later.other links:recover deleted files
