(1) To replace pages or segments of data in memory. Swapping is a useful technique that enables a computer to execute programs and manipulate data files larger than main memory. The operating system copies as much data as possible into main memory, and leaves the rest on the disk. When the operating system needs data from the disk, it exchanges a portion of data (called a page or segment ) in main memory with a portion of data on the disk.
DOS does not perform swapping, but most other operating systems, including OS/2, Windows, and UNIX, do.
Swapping is often called paging.
(2) In UNIX systems, swapping refers to moving entire processes in and out of main memory.

Swaping is a good concept in Operating system.
Using swapping u can execute more bytes in less proccessor memorry
Actually there will be a temporary memorry space and a main processor. Now u have to execute a programand the program is bis than the processor memorry. even then u can execute the program. it can be done this way. Some modules or part of the program will be stored in the procesor memory and some in temporary memory. whenever the processor need the data which is in the temporary space then it would send some data or part of the program to that tempoary space and take the required data from temporary space. THIS CONCEPT OF EXCHENGING IS SWAPPING.

The strategy for swapping bytes depends on the format of the data; there is no universal routine that can take care of all byte ordering differences. Any program that needs to swap data must know the data type, the source data endian order, and the host endian order.

Swapping algorithm:
To swap two variables of similar type: say a and b
Use another variable c of same type.
Copy contents of a or b into c
Copy contents of b or a into a or b
Copy contents of c into b or a

It type of shifting working shifts
For Eg: If you want holiday on Tuesday but your holiday is on Friday and one of your friend is having holiday on tuesday and want leave on friday you both can exchange.
This normally happens in Call Centers, and Big software companies which work 365 days issusing holidays to some of them in week days.
