Operating System (OS): The most important program that runs on a computer is operating system. OS is the term that acts as an interface between the hardware and the user. OS does basic operations such as getting input from the keyboard, displaying output in the monitor and monitoring the files. It is responsible for the management to co-ordinate the activities on a computer system. The responsibilities of OS are bound to get higher when it comes to security, because it provides the access rights for users. Windows: Windows is one of the operating systems that develop new versions frequently. It is an aggregation of operating systems developed by Microsoft. It includes Graphical User Interface (GUI) that helps in displaying the required data on the desktop or monitor. It includes various features like hardware adaptability and interdependence, memory management, task management, access security and many others.

Program Plan Intro

Operating System (OS):

The most important program that runs on a computer is operating system.

OS is the term that acts as an interface between the hardware and the user.

OS does basic operations such as getting input from the keyboard, displaying output in the monitor and monitoring the files.

It is responsible for the management to co-ordinate the activities on a computer system.

The responsibilities of OS are bound to get higher when it comes to security, because it provides the access rights for users.

Windows:

Windows is one of the operating systems that develop new versions frequently.

It is an aggregation of operating systems developed by Microsoft.

It includes Graphical User Interface (GUI) that helps in displaying the required data on the desktop or monitor.

It includes various features like hardware adaptability and interdependence, memory management, task management, access security and many others.
