Computer system



Computer system = hardware + software, and it becomes a computer system that can perform the desired processing only when both are available.

What is software?

 Software is a term that has been used for computer hardware, and means soft work (ware), which means a computer program. However, there are subtle differences between software and programs. In other words, when we talk about a program, we simply indicate the processing procedure (a sequence of instructions) that causes a computer to do a certain task, whereas when we see that a program is overlaid on hardware to create a new computer, software May be called differently.

Software that prepares the program development environment and the computer execution environment is necessary to operate the computer. It is called basic software because it provides basic functions. On the other hand, software that is directly used by general users is called application software. Application software includes programs created by users themselves and programs (application packages) created for specific purposes and sold as packages. The application package is also equipped with various tools so that general users can easily use the computer. For example, seven tools for personal computers include word processors, drawing tools, presentation tools, spreadsheet tools, simple databases, email, and browsers.

Types of software

System software

System software is a series of software that is the minimum required to perform basic control and management of electronic devices, and is a name often used in televisions, video recorders, and home video game consoles. Positioned as basic software, OS will be added to some parts. It is very important because it is software that defines the basic operations of a personal computer, but since the purpose is usually to use applications, it may be rare to be aware of the operating system itself. However, when I move the mouse, the pointer moves on the screen, and when I save what I made, I use the operating system when I am using the computer without being aware of it.

Application software

Software created for a certain purpose (document creation, spreadsheets, etc.) and is also called application software. As a type of application software

Ø  What is produced for a specific company or organization

Ø  Some of them are provided for a fee or free of charge via the Internet.



Hardware

The term hardware (English for “hardware”) covers all the physical components of a computer or smartphone, basically everything that can be touched. The main components, the so-called computer hardware, include:

Ø  Main board (motherboard) to the CPU socket and the card slots

Ø  Processor (CPU), which determines the speed at which your computer works

Ø  Main memory / RAM, which temporarily stores running applications and processes

Ø  Hard drive on which you put your files and programs

Ø  Graphics card that translates your PC's processes into understandable graphics and characters

Ø  Input devices such as a mouse and keyboard that you use to communicate with your computer.

In addition, the hardware also includes all components that react to mechanical or electrical impulses, such as the screen, printer and fax machines, USB sticks or other peripherals. They are also known as " external hardware ". An explanation of the structure of a PC and other interesting information on the individual hardware components can also be found in this article.
