The CPU is one of the most important parts on any computer. Consider it the computer's brain. You would not function very well without a brain and neither does your PC. This component does all of the computations and jobs that are requested whenever a user pushes a button or hits return.
"The CPU has 2 main parts, the Arithmetic/Logic Unit and the Control Unit. These two components control the flow of information through the CPU.

"Control Unit translates programming language into the machine language or binary code (0s and 1s) that the ALU uses for its work. "Just like the name says, this controls all of the CPUs activities. It's the boss. It runs the instructions through the CPU."

"Arithmetic/Logic Unit (ALU): Since the computer is a calculator this part handles the math associated with running a computer. It does addition, subtraction, division, multiplication and logical comparisons lie greater than, less than or equal to"

___________ such as phones, tablet computers, and mp3 players are different from desktop and laptop computers, so they run operating systems that are designed specifically for _____________. Examples of these operating systems include Apple iOS, Windows Phone, and Google Android.
Operating systems for ___________ generally aren't as fully featured as those made for desktop or laptop computers, and they aren't able to run all of the same software. However, you can still do a lot of things with them, like watch movies, browse the Web, manage your calendar, and play games.

An operating system is the most important software that runs on a computer. It manages the computer's memory, processes, and all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer's "language." Without an operating system, a computer is useless.

Step 1

After unpacking the computer and peripherals
Unpack the monitor and computer case from the box. Remove any plastic covering or protective tape. Place the monitor and computer case where you want on a desk or work area.

Think about where you want your desk or work area to be located, and where you want your monitor, computer case, and other hardware to be. Be sure to place your computer case in an area that is well ventilated and that has good air flow. This will help to prevent overheating.

Step 2

Locate the monitor cable. There are several types of monitor cables, so the one on your computer may not look like the one in the image at the left. If you're having trouble finding your monitor cable, refer to the instruction manual for your computer. (If you have an all-in-one computer that's built into the monitor, you can skip to Step 4).

Step 3

Connecting the monitor cable to the VGA port
Connect one end of the cable to the monitor port on the back of the computer case and the other end to the monitor. Hand tighten the plastic-covered screws on the monitor cable to secure it.

Step 4

Unpack the keyboard and determine whether it uses a USB (rectangular) connector or a PS/2 (round) connector. If it uses a USB connector, plug it into any of the USB ports on the back of the computer. If it uses a PS/2 connector, plug it into the purple keyboard port on the back of the computer.

Step 5

Plugging the mouse into a USB port
Unpack the mouse and determine whether it uses a USB (rectangular) connector or a PS/2 (round) connector. If it uses a USB connector, plug it into any of the USB ports on the back of the computer. If it uses a PS/2 connector, plug it into the green mouse port on the back of the computer.

Step 6

If you have external speakers or headphones, you can connect them to your computer's audio port (either on the front or the back of the computer case). Many computers have color-coded ports. Speakers or headphones connect to the green port, and a microphone connects to the pink port. The blue port is the line in, which can be used with other types of devices.

Some speakers, headphones, and microphones have USB connectors instead of the usual audio plug. These can be connected to any USB port. In addition, many computers have speakers or microphones built into the monitor.

Step 7

Plugging the power cable into a surge protector
Locate the two power supply cables that came with your computer. Plug the first power supply cable into the back of the computer case, and then into a surge protector. Then, using the other cable, connect the monitor to the surge protector.

Step 8

Plugging the surge protector into a wall outlet
Finally, plug the surge protector into a wall outlet. You may also need to turn on the surge protector if it has a power switch.
