Top 5 Operating Systems for Computers

Top 5 Operating Systems for Computers

The operating system is the most significant system software which manages the software resources, computer hardware, provides common services for computer programs, and acts as an interface between the hardware and the user. Let’s take a look at the top 5 operating systems for computers.

Each computer system must have at least one operating system to run the other software applications, program management, and for day-to-day operations. Without an operating system, a computer cannot perform any task. Applications like ms word, notepad, chrome browser, Photoshop etc, need some environment to run and perform their functions. You can’t even play any kind of computer game without an operating system.

  • The first operating system was developed in the early 1950’s. It was also called a single-stream batch processing system because it presented data in groups.
  • The first operating system used for real work was GM-NAA I/O, produced in 1956 by General Motors’ Research division for its IBM 704.
  • The IBM systems/360 is the first operating system sold along with a computer which was invented by IBM in1964 to operate its mainframe computer.          
  • Gary Arlen Kildall, an American computer scientist and microcomputer entrepreneur who created the CP/M operating system and founded Digital Research, Inc., is known as the Father of Operating System.

The Most Popular Operating Systems of this period are Windows OS, Mac OS, LINUX OS, UNIX, iOS, Android, VMS, AIX, z/OS, Fedora, Chrome OS, KALI LINUX OS, Ubuntu, Solaris etc.

Here we are going to discuss about Top 5 Operating Systems for Computers and their features with full information.

1. Microsoft Windows

Bill Gates and Paul G. Allen founded Microsoft in 1975. The name was derived from the words microcomputer and software. Windows is the most popular and user-friendly operating system on this list. Bill Gates the co-founder of Microsoft Corporation introduced the first version of the windows (Windows 1.0) operating system in 1985. Unlike MS-DOS, windows used the Graphical User Interface (GUI) system and allowed users to run multiple applications at the same time using multitasking features. Over the past three decades, Windows has become one of the most popular operating systems for personal computers.

Windows OS
Windows Operating System

The first version was windows 1.0 which was released on November 20, 1985. Since then, the Windows OS has gone through several major updates.

Some of the most notable windows versions are – Windows 3.1 (1992), Windows 95 (1995), Windows XP (2001), Windows 7 (2009), Windows 10 (2015), and Windows 11 (Will be released between October and November 2021). Windows Operating System held the number one position for their market demand among the ‘top 5 Operating Systems for computers’.


  • Windows uses the Graphical User Interface (GUI) technology. It makes the system easier for a new user to learn and use because there is no need to memorize the command.
  • The Task View feature lets the users switch between multiple workspaces at once, by displaying all the open Windows.
  • Windows can run programs with size greater than 640 kb.
  • It automatically compresses system files to reduce storage footprint.
  • OLE (Object Linking and Embedding) helps to embed the output of an application into another application with automatic updates.


  • The user interface of windows is simple and also easy to use than UNIX and Mac OS.
  •  Windows platform is best suited for software and game developers.

Apple was founded by Steve Jobs, Steve Wozniak, and Ronald Wayne in 1976 to develop and sell Wozniak’s Apple I personal computer. Apple and Macintosh computers run on the proprietary Mac OS and OS X system, the first of which launched 20 years ago. There are also previous or updated versions available, which include – Kodiak (OS X 10 Beta), Lion (OS X 10.7), Mountain Lion (OS X 10.8), Mavericks (OS X 10.9), Yosemite (OS X 10.10), El Capitan (OS X 10.11), Sierra (Mac OS 10.12), High Sierra (Mac OS 10.13), Mojave (Mac OS 10.14) and Catalina (Mac OS 10.15).
