Operating System: This The Definition, Functions, and Types

Operating System – In general, the operating system is the first layer of software that is placed in a computer’s memory when it boots up. While other software is run after the system program and will perform core services for the software.

Before there was an operating system, computers only used analog signal systems and digital signals. Along with the development of knowledge and technology, at this time there are various operating systems with their respective advantages.

The system program has a systematic schedule that includes calculating memory usage, data processing, data storage, and other resources. Examples of modern operating systems are Linux, Android, iOS, Mac OS X, and Microsoft Windows.

According to the Experts

In addition to understanding operating systems in general, campus IT will also explain the definition of operating systems according to experts

According to Lim Rusyamsi

A software that can perform the task of controlling and managing hardware as well as other basic system operations and can also run application programs.

According to MCLEOD (PEARSON)

Operating systems are computer programs that manage our computer’s hardware and software resources


All application programs/software on a computer require a system to run.

According to M. Suyanto

A system consists of several software components or software that has a function to control all activities that have been carried out by the computer.


The software in the first stage is entered into the computer’s memory when the computer is turned on

Operating System Functions

1. Computer Resource Management

The operating system can set the time applications are running, share CPU usage when applications are running concurrently, grant disk access, and so on.

2. Acts As A Basic Application Of A Device

The operating system is the basis of the formation of existing programs on a device. You could say this is a vital part that regulates all the things needed to carry out the functions of a device.

3. Connecting Hardware

The operating system plays a role in coordinating all the devices that are connected to each other at the same time, such as internal storage, mouse, speakers, and CPU.

In this case, the operating system acts as a bridge that connects the hardware with the software. It will then in turn perform basic computer operations.

4. Optimizing the Functions of a Device

The operating system is able to optimize the performance of both hardware and software, the system regulates and controls the relationship between hardware and software so that they can work together well.

5. Setting Device Work System

The operating system regulates and controls all the functions of the hardware used, from the CPU, hard disk, memory, and so on. Of course, with the system program, all devices can synergize with each other and form a unity to maximize the function of a device.

Types of Computer Operating Systems

The following are some of the types of operating systems that run on the computer:

1. Stand-Alone Operating System

The Stand-Alone can be used by single users or multi-users, this operating system also has features that are quite complete and can stand alone. Examples of stand-alone operating systems are Microsoft Windows, Linux, and Mac OS

2. Live CD Operating System

Live CD only requires a CD/DVD room device without the need to permanently install it on the computer to run it. This system program is very light because of its small size. But the live CD does not have many features compared to a stand-alone system program. Here are examples of live CD operating systems, namely Knoppix, Centos, Linux Mint, Win XP live CD, and others.

3. Embedded

This system is directly on the computer and cannot stand alone, it has special functions and specifications. Examples of Embedded Systems programs are eCOS, LynxOS, JavaOS, and Embedded Linux.

4. Network

Operating SystemSome examples of network operating systems are Red Hat, Centos Server, Cloud Linux, and so on.

Hopefully useful information about the operating system, both the definition, function, and type. Waiting for other interesting information, BSI Today will provide other information.
