This course offered at SCAAD College will introduce you to modern operating systems. We will focus on common operating systems, including Windows. The course will begin with an overview of the structure of modern operating systems.

An operating system (OS) is an important part of almost every computer system.
Most computer users have had some experience with an operating system, but it is difficult to pin down precisely what an operating system.

An operating system acts as an intermediary between the user of a computer and computer hardware. The purpose of an operating system is to provide an environment in which a user can execute programs in a convenient and efficient manner.

This interface is either command line user interface or Graphical User
Interface. Command Line User interface is used in operating systems like
MSDOS, UNIX, LINUX etc. and GUI is used with most of MS Windows operating
systems like Windows XP , Windows Vista Windows 7 etc.

To provide a grand tour of the major operating systems components

Advantage of Operating System

Allows you to hide details of hardware by creating an abstraction
Easy to use with a GUI
Offers an environment in which a user may execute programs/applications
The operating system must make sure that the computer system convenient to use
Operating System acts as an intermediary among applications and the hardware components
It provides the computer system resources with easy to use format
Acts as an intermediator between all hardware’s and software’s of the system

Disadvantages of Operating System

If any issue occurs in OS, you may lose all the contents which have been stored in your system
Operating system’s software is quite expensive for small size organization which adds burden on them. Example Windows
It is never entirely secure as a threat can occur at any time

What is Kernel in Operating System?

The kernel is the central component of a computer operating systems. The only job performed by the kernel is to the manage the communication between the software and the hardware. A Kernel is at the nucleus of a computer. It makes the communication between the hardware and software possible. While the Kernel is the innermost part of an operating system, a shell is the outermost one.read more
