Definition and Types of Operating Systems

Definition and Types of Operating Systems - The operating system functions as a link between hardware and software on the computer.

Some operating systems only allow one application to run at a time such as DOS, but most new operating systems allow several applications to run simultaneously smoothly without any obstacles.

Definition and Types of Operating Systems

If several system applications run simultaneously, the computer operating system will set the right schedule so that as much as possible all processes on the running computer get enough time to use the CPU and not interfere with each other. Operating systems like this are called multi-tasking operating systems such as the UNIX operating system.

Definition of Operating System

An Operating System (operating system; OS) is software or software that is used to manage all resources in a computer that is located in the first layer when booting and is placed on the hard disk memory, without an operating system users cannot run applications programs on their computers except the boot application program.

An operating system generally consists of several parts:

- Boot mechanism, which puts the kernel into memory

- Kernel is the core of an operating system

- Command interpreter or shell, which is in charge of reading input from users by applications.

Libraries provide a collection of basic and standard functions that can be called by other applications. Drivers interact with external hardware, as well as control it.

Types of Operating Systems

Some types of operating systems are as follows

1. Unix Operating System

The Unix Operating System is the oldest operating system created and operated using only Text Mode, meaning that the system does not display graphics mode (images). The UNIX operating system was developed by the AT&T Bell Laboratories company. UNIX is used to run computer networks.

Initially, UNIX was a command-line interface-type operating system. This situation makes it difficult for new users. To facilitate use, UNIX is now also provided in the Graphical User Interface version.

Unix that uses the POSIX operating system interface, such as SCO UNIX, the BSD (Berkeley Software Distribution) family, GNU/Linux, Zeath OS (based on a modified Linux kernel), MacOS/X (based on a modified BSD kernel, known as Darwin) and GNU/Hurd.

2. Mac OS Operating System

Mac OS is short for Macintosh Operating System. This GUI-based Operating System was released by a company called Apple Computer founded by Steve Jobs in 1984, Mac OS is a paid OS that is sold along with the hardware. At that time, Mac OS technology was considered the most advanced.

Unfortunately, this greatness could not be maintained. In the following years, Mac OS lost out to Microsoft Windows. Until now, Mac OS is still being refined in order to compete with Microsoft Windows. Mac OS is a Unix-derived OS, Mac OS versions include Cheetah, Puma, Jaguar, Panther, Tiger, Leopard, Snow Leopard, and Lion.

3. Microsoft Windows Operating System

Microsoft Windows Operating System is an operating system created by a company called Microsoft founded by Bill Gates, windows is an OS that was derived from DOS (Disk Operating System). This operating system is multi-tasking and multi-user. Not surprisingly, the Microsoft Windows operating system is very popular. Here's the Microsoft Windows Version:

- Windows Desktop Environment (version 1.x to version 3.x)

- Windows 9x (Windows 95, 98, and Windows ME), and Windows NT (Windows NT 3.x, Windows NT 4.0, Windows 2000, Windows XP, Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7 (Seven) which was released in 2009, and Windows 8 which was released in October 2012)).

Windows operating system is a licensed operating system that requires the user to buy/pay for the license.

4. LINUX Operating System

The LINUX Operating System is a development of UNIX. This operating system was originally created by Linus Torvalds, a student in Finland. LINUX which was created in 1991 was then developed by programmers in the world.

5. Android Operating System

Android Operating System is an operating system that was derived from Linux originally created by a company called Android Inc. which was eventually bought by Google. Android is an operation that is used on mobile devices such as Smartphones, Tablets, Phablets, etc. Android versions: 1.0, 1.1 Cupcakes, Donut, Eclair, Froyo, Gingerbread, Honey Comb, Ice Cream Sandwich, Jelly Bean, KitKat.
