An Abbreviated History of Operating Systems

Operational system is a set of software tools that perform the functions to provide the user with a software interface with hardware and improve the functioning of a computer system through the rational management of its resources.

Computer technology has recently made a significant leap forward, and soon it will be impossible to imagine our life without a PC. But a computer without an operating system is only a set of chips. All the programs that we use work on the basis of the operating system (OS). OS influences the speed and performance of our work on the computer.

We know that the computer was invented by English mathematician Charles Babbage in the late 18th century. It is also known that that computer didn’t have an operating system.

Some progress in the creation of digital computers occurred after World War II. In the mid-1940s, the first tube computing devices have been created. At the time one group of people was involved in the design, operation, and programming of the computer. Programming was carried out exclusively in machine language. Nobody talked about operating systems.

Since the mid-1950s, a new period in the development of computer technology began, coupled with the emergence of a new technical base – semiconductor elements. The second-generation computers were more reliable; they were now able to operate continuously for long time and solved real problems of practical importance. There was a division of staff into programmers and operators, system owners and developers of computers. In those years, the first algorithmic languages appeared and, consequently, the first software system – compilers.

The next important period in the development of computers refers to the years of 1965-1980. Software compatibility required operating system compatibility. These operating systems would have to work on large and small computer systems, with a large and small amount of a variety of peripherals, in the commercial field and in the field of scientific research. This was also a period when a new type of operating system appeared – the system of separation of time, which was aimed to create the illusion of using a sole computer for each individual user.

The next period in the evolution of operating systems is associated with the emergence of large-scale integrated circuits (LSIs). In those years there was a sharp increase in the degree of integration and cheaper chips. The computer was now available to every individual, and the era of personal computers began. There were two systems that dominated the market: MS-DOS and UNIX.

Operational system is a set of software tools that perform the functions to provide the user with a software interface with hardware and improve the functioning of a computer system through the rational management of its resources.

Computer technology has recently made a significant leap forward, and soon it will be impossible to imagine our life without a PC.
