Basic Computer Parts and Functions
Monitor
The computer monitor is the screen on the computer on which we can see what we are doing. The monitor is an output device which shows us how the computer is interpreting our inputs through various input devices. The monitor is our way of knowing whether the computer has understood our commands or not. The simplest example of this is typing. When we type a word on the keyboard, it comes up on the monitor. By this we know that the computer is able to understand what we are typing.
Keyboard
The second most basic computer part is the computer keyboard. The keyboard is an input device which we use to enter data. Keyboard helps us tell the computer what we want it to do. So whether we want to type some numbers or some letters, we tell the computer what it is we want to type by 'keying' in the corresponding letters on our keyboard.
Mouse
The computer mouse is a device which helps us navigate through different programs. The mouse is a kind of facilitator on the computer and helps us give the computer commands which the keyboard cannot. Or commands which would otherwise take a longer time to give on the keyboard. For instance, if you want to start Internet Explorer on your computer, you can press a succession of keys and get there, or simply double-click the Internet Explorer icon with the mouse. The mouse makes a lot of things simpler.
CPU
The Central Processing Unit (CPU) is known as the brain of the computer. The CPU helps the computer receive, analyze and make sense of the input. The CPU also, based on the input, helps computer generate the output. CPU helps coordinate all the inputs and outputs of the computer.
Like a brain has one sense-and-respond wing and a memory wing, so does the CPU. While CPU helps the computer give the outputs based on the inputs, it also helps 'save' important stuff. It has a computer memory area which can help in data storage and hence when you save a file, it is saved into the memory of the computer.
CD Drive
The CD Drive is an appendage to the CPU. A lot of times, we need to bring data from another computer to our computer. We bring it in the form of an external memory device known as a CD (Compact Disc). Now in order to transfer the information and data on the CD to the computer, we need to have a device which will help you 'read' what's written on the CD. This is where the CD drive comes in. The CD drive helps the computer read information off the CD.
