All About Computers -For the layman

On this post,let me explain how a computer works from whatever I have learned. If you own a computer, you must see a display or a monitor, a tower-like cabinet called the CPU or Central Processing Unit,a keyboard and a little device called the mouse. You may also probably own a printer or a scanner. The tower-like structure called the CPU is the most important part of your computer. It has the necessary parts to perform all the operations. All these parts are just hardware and we need something which performs the operation. That is called software, which is essentially a set of programs which perform the tasks. Operating system is the mother of all this software which sends commands to various devices and monitors the control.You must have noticed something like "Windows" or "Mac", when you start your computer. That is called the Operating system. Inside the CPU, there are many parts like the motherboard which houses all the chips,memory and other devices. Suppose you are trying to add two numbers and want the result. The Operating system will reserve some memory space for the numbers, send necessary commands to the processing unit and finally displays the result on the monitor.
