Computer System Concepts

Concept of Computer

The computer is an electronic device that processes the data inputted by the user and provides information as a result, that is, a computer is an electronic machine that follows the instructions given by the user. It has the ability to store, retrieve and process data. You can use the computer to type documents, send emails, play games, and browse the web. You can also use it to create spreadsheets, presentations, and even videos.

Computer System Concept (Concept of Computer)

A computer system is a combination of hardware and software. The physical and tangible parts/components of a computer that can be seen and touched are known as hardware. The hardware consists of the physical components of a computer system such as input devices (keyboard, mouse, scanner, etc.), output devices (monitor, printer, speakers, etc.), processing devices (CPU), and storage devices compact disc, hard disk, DVD, etc.

Software is the set of programs and instructions that control the operation of a computer system. A computer system cannot do anything by itself. The computer does the work that is instructed by the user. The programs written on the computer are written in the language understood by the computer.

A group of units working to achieve one or more objectives is called a "System". For example – Hospital is a system whose units are Doctor, Nurse, Medical, Treatment, Operation, Peasant, etc. Similarly, the computer also acts as a system that has the following parts.

• Hardware
• Software
• User

Hardware

Those parts of the computer which we can touch and see are called Hardware. Like-Keyboard, Mouse, Printer, Scanner, Monitor, CPU, etc.

Software

Those parts of a computer that we cannot touch but can only see are called software. Like- MS Word, MS Excel, MS PowerPoint, Photoshop, PageMaker, etc.

 

 

User

Those people who run the computer, operate it and get the result are called users.

Summary Words

1. A group of units working together to achieve one or more objectives is called a "system".
2. The parts of the computer that we can touch and see are called hardware.
3. Those parts of a computer that we cannot touch but can only see are called software.
4. The person who operates the computer and receives the result is called the user.
5. Hardware, software, and user three are the main parts of the computer system.
