Operating System An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. It is a program designed to run other programs on a computer. The operating system is an essential component of the system software in a computer system. Application programs usually require an operating system to function. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software

1 INTRODUCTION The hard disk is a magnetic disk used typically to record and store information‚ whenever we save data or install a program on a computer. The information stored in the hard disk does not get deleted when the computer is turned off. Disk partitioning is the process of dividing the hard disk data storage space into separate areas called partitions. Disk partitions will usually take place or get created the first time the hard disk is prepared for usage. After the disk has been

However‚ many operating systems—such as Windows XP and Solaris—treat processes and threads differently. Typically‚ such systems use a notation wherein the data structure for a process contains pointers to the
