multitasking: more task execute on sevaral cpumultithreading : sevaral part of one program execution
MULTITASKING!! Multitasking Another technique that helps servers use their system resources more efficiently is multitasking, which is the execution of multiple tasks at one time
walking and eating a ice cream cone is multitasking. if your doing more than one thing at the same time then its called multitasking.

An example of a multitasking operating system is the system at a school. You use many programs and do many tasks at the same time, so you are multitasking on the computer
multitasking
Preemptive Multitasking basically involves the operating system sharing CPU time among many processes. An executing process is terminated when its time slice finished and the the CPU control is given to the next process. All processes get CPU time. In Cooperative Multitasking, however, one process can hold the CPU for as long as it needs it. For the cooperative to work, all programmes must cooperate, hence the name.
Cooperative multitasking is multitasking tohelp someone else, while peemative multitasking is multiaatsking for yourself.
They call this multitasking.
Mike Newton Cooperative Multitasking:- When computer usage evolved from batch mode to interactive mode, multiprogramming was no longer a suitable approach. Each user wanted to see his program running as if it was the only program in the computer. The use of time sharing made this possible, with the qualification that the computer would not seem as fast to any one user as it really would be if it were running only that user's program. Early multitasking systems consisted of suites of related applications that voluntarily ceded time to each other. This approach, which was eventually supported by many computers operating systems, is today known as cooperative multitasking. Although it is rarely used in larger systems, Microsoft Windows prior to Windows 95 and Windows NT, and Mac OS prior to Mac OS X both used cooperative multitasking to enable the running of multiple applications simultaneously. Windows 9x also used cooperative multitasking, but only for 16-bit legacy applications
