Evolution of OS : All You Need To Know

Rashid Khan Avatar


An Evolution of OS (operating system) is a vital software program that acts as the primary interface between the user and the hardware components of a computer system. It serves as a crucial link by facilitating communication and coordination between various software programs, computer resources, and hardware devices.

Without an operating system, a computer would be nothing more than a collection of hardware components without any means of interaction or functionality.

The Evolution of OS plays a pivotal role in managing and controlling all software and hardware resources, such as file storage, memory allocation, input/output operations, and peripheral devices like printers and disc drives.

Over the years, operating systems have evolved significantly to meet the changing demands of technology.

From simple command-line interfaces to user-friendly graphical user interfaces (GUIs), they have undergone numerous advancements to enhance their usability and performance. These developments have been driven by the increasing complexity of computer systems and the need for efficient management of resources.

What is Evolution of OS (Operating Systems)?

The evolution of operating systems is like a journey through the technological ages. It started with the simplest of commands, evolving into sophisticated interfaces we have today. Think of it as a story of how our computers went from basic binary operations to multitasking, user-friendly environments.

Each stage brought new features, improved efficiency, and user convenience. From punch cards to graphical user interfaces, the OS evolution mirrors the rapid progress in computer technology. It’s a fascinating tale of adaptation and innovation.

The Evolution of OS can be traced through four distinct generations, each reflecting significant advancements and innovations in computing technology and functionality.

The first generation of Evolution of OS emerged in the 1950s with the advent of electronic computers. These early systems were primarily designed for batch processing, using punch cards or paper tape as input and producing output on printers.

They had limited capabilities and were mainly used for scientific and military applications.

The second generation, which emerged in the 1960s, introduced the concept of time-sharing, allowing multiple users to access a single computer simultaneously.

This era also saw the development of high-level programming languages such as COBOL and FORTRAN, making it easier to write programs for computers.

In the 1970s, the third generation of operating systems saw further advancements in hardware technology, with the introduction of integrated circuits and microprocessors. This led to faster processing speeds and increased memory capacity, allowing for more complex operations and multitasking capabilities.

First Generation Evolution of OS (1945-1955)

The Evolution of OS dates back to the early days of computing, when serial processing was the predominant method. This marked a significant shift from mechanical computers to electronic computing systems, as it offered a more efficient and reliable alternative.

In contrast to mechanical devices which were prone to flaws and human error due to their limited speed and capabilities, electronic computers had the potential for faster processing and greater accuracy.

However, one major drawback of this early generation of computers was the lack of an operating system. This meant that instructions had to be executed immediately, without any buffering or scheduling by a central program.

As a result, the computer’s performance was solely dependent on the speed at which instructions were given and processed.

Second Generation Evolution of OS (1955-1965)

The second generation of Evolution of OS, known as batched systems, marked a significant step in the evolution of computer technology.

This era saw the implementation of batch processing, a method that allowed for tasks to be completed sequentially and in a series. Unlike the first generation of computers, which did not have an operating system, this generation introduced various operating system functionalities such as FMS and IBSYS.

The primary goal of batch processing was to improve computer utilization and application by efficiently managing jobs.

To achieve this, jobs were scheduled and submitted on cards and tapes. These jobs were then executed successively on the monitors using Job Control Language. The first computers used in this method created a continuous stream of jobs without any pauses or stops. The software was typically written on punch cards and then transferred to the tape processing unit.

One significant drawback of this system was its inconvenience for users. However, it was designed to keep the expensive computers as busy as possible by running a leveraged stream of operations.

Third Generation Evolution of OS (1965-1980)

As technology advanced and computer systems became more sophisticated, the evolution of operating systems entered its third generation.

This phase marked a significant shift from single-tasking to multi-programming. With the introduction of multi-programmed batched systems, the operating system was now capable of serving multiple users at once.

This major development allowed for interactive users to communicate with the computer through online terminals, making it a multi-user system. This enabled different individuals to access and use the computer simultaneously, greatly increasing efficiency and productivity.

One of the key features of third-generation operating systems was their ability to perform multiprogramming. This meant that multiple jobs could be executed concurrently by being stored in the main memory. This was a major improvement from earlier generations where only one job could be run at a time.

To manage and prioritize these multiple jobs, third-generation operating systems utilized job scheduling algorithms. These algorithms determined which program should be run by the processor at any given moment based on various factors such as priority level and resource availability.

Fourth Generation Evolution of OS (1980-Now)

During the age of networked computing, the operating system played a crucial role in connecting computers to one another.

This era was characterized by the widespread use of graphical user interfaces (GUIs), providing users with a comfortable and visually pleasing way to interact with their computers. In the fourth generation, two new operating systems emerged – the time-sharing operating system and the Macintosh operating system.

The introduction of time-sharing operating systems had a significant impact on the evolution of operating systems. It allowed multiple users to access a single computer simultaneously through individual terminals, while also dividing the processor’s time among them.

To interact with these systems, users needed printing ports which utilized a command-line interface where responses and commands were written out on a roll of paper.

This type of interaction was previously used in batch processing systems, where users communicated directly with the computer through printing ports similar to electric teletypes.
