The notion and the types of operating systems
Pojęcie i rodzaje systemów operacyjnych
about various operating systems,
about the function of the computer operating systemoperating system,
to identify various operating systems and to use English vocabulary related to operating systems.
An operating systemoperating system is an integral and inseparable part of the computer system, without which the computer cannot be used.

is a softwaresoftware which manages the computer system and creates an environment for executing and controlling the user’s tasks.
First computers allowed to run only one programme. Punch cards or magnetic tapes were used in order to enter the programme and data into the system. The role of the computer system at that time was limited to the use of the defined programming language – and that is why the programmes written in that specific language could be executed.

Relatively low speed of the input/output devices (card reading, printing) in comparison to the time of executing the programme by the computer resulted in low effectiveness of using the then very expensive computer.

The way to avoid this problem was to permanently upload to the computer memory the softwaresoftware that manages hardware and the communication between the hardware and the user. Therefore, repeating these operations was not necessary while executing any user programme.
Another important thing was to notice that while performing input / output operations, the computer is significantly less loaded than during the execution of the programme itself. Hence the idea to use the computer processor for the execution of another programme, while executing the input/output operations. Such a feature of the concurrent execution of multiple tasks is called multitaskingmultitasking. The operating systemoperating system gained the ability to manage the processor and memory so that multiple processes could use them simultaneously.
With the arrival of floppy disk drives and hard disks the operating systemoperating system also began to manage the storage mediastorage media and the data stored in them.
The next revolution in the design of operating systems was to enable several users to work on the same computer at the same time, which is called multiple accessmultiple access. User accounts, which allowed multiple users to conveniently use one computer, were introduced to desktop computers.
When first computer networks were launched, it was necessary to equip the operating system with network functionsnetwork functions. In the initial stage all operating systems were text systems. It required knowing the commands entered by the user with the keyboard.
In order to make computers easier to operate for „computer laymen”, along the enhancement of computing powercomputing power of the available computers, a graphical environment (GUI, i.e. graphical user interfaceinterface) was introduced, which increased the efficiency and easiness of its use. With time basic applications were introduced to graphical operating systems, which enabled to carry out simple operations, e.g. a calculator, a text editor or a simple graphics programme.
