Computer System:

A computer system is a basic or complete functional computer including all the hardware and software required to make the computer functional for the end user.

The computer system should have the ability to receive the user input and process the user data and create information for storing the data or generate the output of the processed data.

A computer system is the interconnected computers that share a central storage system and various peripheral devices such as printers, scanners, routers.

Each computer is connected to the system can operate independently, but has the ability to communicate with other devices and computers.

A computer system allows users to input, manipulate and store data.

Computer systems typically include a computer, monitor, keyboard, mouse and other optional components.

All of these components can be integrated into all-in-one unit such as a laptop computers.

Parts of the Computer:

Computer consists of three different types of categories 1. input 2. processing 3. output

1. input components are keyboard, mouse, touch screen, scanner, mic etc. 2. processing components are micro processor, ram, rom, cache. 3. output components are monitor, printer, speaker, projector etc.

Along with these components we are using connectivity component s like bus cables.

Computer Memory:

Memory is divided into two types will be available in the following devices: 1. Primary Storage Devices (RAM, ROM, CACHE) 2. Secondary Storage Devices (CD, DVD, Hard Disk, Pen drive, etc.)

How the computer works:

Computer works on the basis of I-P-O principle (input processing output). Computer will accepts the input through the input devices and process that input(information or data) and finally generates the output. Here the end user sends the input/information to the computer through the input devices and this information will sent to the operating system where the information will be converted into the computer understandable format(binary format). Now the information will be getting processed by microprocessor and generates the output in the computer understandable format only. Now once again operating system reconverts the output which is available in the computer understandable to user understandable format.
