Introduction:
Operating systems have been an essential part of modern computing since the earliest days of computers. They are the software that controls and manages computer hardware and software resources, making it easier for users to interact with their devices. Operating systems have undergone significant changes since the first ones were developed.
In this blog, we will take a look at the evolution of operating systems.
The earliest operating systems:
The earliest computers were large, room-sized machines that were programmed using punch cards or paper tape. These early machines did not have an operating system in the modern sense of the term. Instead, each program had to be loaded and executed manually. However, as computers became more sophisticated, it became clear that an operating system was needed to manage their resources and make them easier to use.
Batch processing systems:
The first operating systems were developed in the 1950s and 1960s. These early operating systems were known as batch processing systems because they processed data in batches rather than in real-time. Batch processing systems allowed users to submit jobs to the computer, which would then be executed one after the other. The first operating system to use batch processing was the GM-NAA I/O, developed by General Motors and IBM in the late 1950s.
Time-sharing systems:
In the 1960s, a new type of operating system was developed known as time-sharing systems. Time-sharing systems allowed multiple users to access a computer simultaneously, with each user having their own terminal. Time-sharing systems were much faster than batch processing systems because they allowed users to interact with the computer in real-time. The first time-sharing system was the Compatible Time-Sharing System (CTSS), developed at MIT in the early 1960s.
Multi-programming systems:
In the 1960s and 1970s, a new type of operating system was developed known as multi-programming systems. Multi-programming systems allowed multiple programs to run at the same time, with the operating system dividing the computer's resources among them. This made it possible to run several programs simultaneously, which greatly increased the efficiency of computer systems. The first multi-programming operating system was the Atlas Supervisor, developed at the University of Manchester in the mid-1960s.
Network operating systems:
In the 1980s and 1990s, the use of computer networks became more widespread. Network operating systems were developed to manage and control networks of computers. These operating systems allowed users to access resources on remote computers and share data and resources with other users on the network. Examples of network operating systems include Novell NetWare and Microsoft Windows NT.
Graphical user interfaces:
In the 1980s and 1990s, graphical user interfaces (GUIs) were developed, making it easier for users to interact with their computers. GUIs use icons, menus, and windows to represent computer programs and files, making it easier for users to navigate and interact with their devices. Examples of operating systems that use GUIs include Microsoft Windows, Apple macOS, and Linux.
Mobile operating systems:
In the 2000s and 2010s, mobile devices such as smartphones and tablets became increasingly popular. Mobile operating systems were developed to run on these devices, providing users with a touch-based interface and access to mobile-specific features such as GPS and cellular connectivity. Examples of mobile operating systems include Apple iOS, Google Android, and Microsoft Windows Mobile.
Cloud operating systems:
In the 2010s, cloud computing became increasingly popular. Cloud operating systems were developed to manage and control cloud-based resources. These operating systems allow users to access resources on remote servers and manage their applications and data in the cloud. Examples of cloud operating systems include Amazon Web Services and Microsoft Azure.
