Windows OS – Introduction

It is called as windows because each program runs inside a separate window on the screen. A window is a box or frame on the screen. Many number of windows can be run on the screen simultaneously, each containing its own program. The window which appears on the top is called the foreground window. The other windows are called background windows. The
importance to each of these windows can be controlled by the program manager. Any window can be made foreground or background by switching between windows using
the input device (mouse /keyboard). With certain limitations windows allows copying material from one to another.
