Transcript of Copy of Computer Parts: Explained
Parts of the Computer Heat Sink Random Access Memory Hard Drive Power Supply Unit Power Button Computer Case Tower Case Desktop Case Monitor Keyboard Mouse Central Processing Unit Power Button The Computer Case holds the motherboard, CPU, power supply, and many other essential parts to a computer. Some computers, called "all-in-one computers," do not have a computer case because all its essential parts are built into the monitor itself. There are two types of computer cases, they serve the same purpose but in different forms. A Desktop Case is a small Computer Case. It usually lays under the Monitor. The tower case sits on the floor next to the monitor of a computer. It usually has ports and many other features on the front of the case. A monitor is the screen which most people call the computer. Monitors come in a variety of models. Some monitors are just a screen with either LED or LCD back lighting. But other monitors have USB ports, volume adjusters, and many other different tools. Power Cord The power cord is the tool which brings energy (or power) to a computer. If the power cord is not connected to an outlet the computer will not turn on. With the technology available there are many different kinds of keyboards. There are wireless keyboards and keyboards that plug into the monitor or case. There are kenesis keyboards, flexible keyboards, and even projecting keyboards. But, all of these different types of keyboards basically do the same thing. They use letters and numbers to communicate with your computer and insert data. As with the keyboard, there are also many different types of computer mice. Again, there are corded and non-corded, optical and mechanical, track pads, and a plethora of other types of a mice. The computer mouse is the pointer, clicker, and mover that allows you to operate on your computer screen. The power button is the button that, when pressed, turns on the computer. The energy that is coming from the power cord is sent to the power supply unit when the power button is pressed. Also the power button turns on the computer's BIOS. While all this is loading one is usually looking at the "start-up" screen. Motherboard The Motherboard is the main circuit board that holds all of a computer's essential parts. These parts include the Central Processing Unit, the Hardware, the Random Access Memory, and many other things. The Motherboard is involved in every operation of a computer. The Central Processing Unit (CPU) is the brain of a computer. Whenever you are typing or using the mouse the CPU is reacting to and completing every command. The CPU fits inside of the Motherboard. The Heat Sink fits around the CPU. The Heat Sink's main job is to absorb the heat that the CPU produces. The Random Access Memory (RAM) is also held inside of the Motherboard. RAM is a short-term storage held on a computer. Every time a computer is turned off the RAM is shut down. Long-term storage can be found in the Hard drive. The Hard drive is the long-term storage of a computer. When you save a file it save to the Hard drive. Opposed to RAM, the Hard drive is what stores documents for long term use. Universal Serial Bus The Universal Serial Bus (USB) is used to connect many things like thumb drives, a computer mouse, keyboards, cameras and many other things. The USB connects to the Motherboard of a computer. Graphical User Interface Graphical User Interface (GUI) combines graphics and text to make a screen that the mouse can click and interact with. Before GUI was invented all data had to be entered using text only. The power supply unit transfers the energy from the outlet to a type of power that the computer can use and sends this new energy to all the parts of the computer that require energy. Audio Ports An audio out port is the place where headphones or speakers should be plugged into, this is the way to get noise out of the computer. The audio in port is where audio is put into the computer via microphone or headset. Optical Disc Drive The optical disc drive processes CDs and DVDs. They are usually incorporated into the computer case. However all-in-one computers have the drive on the side of the monitor. Operating Systems Web Camera Basic Input/Output System When you turn on the computer, the BIOS runs tests to make sure that everything is working right. The BIOS also makes sure that all the components are working together. It performs many other crucial tasks. Modem and Router The modem is the tool which a computer uses to connect with the internet. The modem only connects one computer to the internet. But with a router the internet can be used by several computers or mobile devices at one time. A Web Camera takes images directly on the computer. It can also be used for Skype and Face Time. These cameras are built-into some computers, but if web camera are also available for purchase. The Operating System (OS) controls the hardware and software on a computer. All parts of a computer need to access the CPU; the OS makes sure that all the components wait their turn to access the CPU. Many types of OS are offered, these include OS X (made by Mac) and the Windows 7 (PC). Sources:Full transcript
