Introduction to Operating Systems
Computer software can be divided into two main categories: Application software and system software. Application software consists of the programs for performing tasks particular to the machine‘s utilisation.
On the other hand system software provides a general programming environment in which programmer can create specific applications to suit their needs. System software acts as an interface between the hardware of the computer and the application software that users need to run on the computer. The most important type of the system software is the operating system.
Operating System:
An operating system is a program that acts as an interface between a user of a computer and the computer hardware. The purpose of an operating system is to provide an environment in which a user may execute programs. The primary goal of an operating system is to make the computer convenient to use, and the secondary goal is to use the hardware in an efficient manner.
In these tutorials we briefly described about the history, the types and the functions of operating systems. In the next tutorials we introduce the topic of operating systems by discussing the several key parts of operating systems such as processes, memory and file managers. The basic concepts of Operating Systems are processes, memory management, I/O management, the file systems, and security.
We provide operating system concepts tutorials for the educational purposes only. We do not responsiable for the correctness of its contents. the risk of using it lies entirely with the user.
