Operating System:

A program that is initially loaded into the computer memory and manages all the other programs and resources of a computer is called Operating system.

The operating system manages the applications and the hardware, such as disk drive, memory, and peripheral devices.

The users interact with the operating system by using the command language or shell, and the graphical user interface.

An application makes the service request by the application programming interface to use the operating system.

Operating system performs different type of services

Determining the running application and its order

Time allotment to each application

Expert Solution & Answer

Explanation of Solution

Main objective of early operating systems:

In early days, computer system has no Operating system at all, and is characterized as serial processing. By using a serial processing technique the programs are executed.
Earlier, the cost of computer systems were high and because of that computer time was used efficiently without any wastage of time.
The time slots are reserved by the users in advance, and during the allotted period, they occupy the computer exclusively.
A card is used to represent the program and with the help of card readers, the programs are loaded into memory.
Before loading the program, the user has to load the compiler to compile the program. The user has to find errors if any and should re-punch all cards from beginning.
In given time, if the user failed to complete the task, then the user has to wait for long time to execute again. This was a waste of time for the user.
