Multi-tasking:it is nothing but a single system with one
processor performs execution of more than one process.
Multi-user:multi-user may be defined as using of same
process or program by no of users at a single unit of
time.EX:when we consider google database it is accessed by
millions of users at a time from different parts of world.
Multi-processing:multi-processsing is a special technique
in which a single system consists of more than one
processors and each process is done by all the processors.
Advantage:Each process is executed in very small amount of
time.
Disadvantage:It is very costly process.
Time-sharing:time-sharing is a process in which if there
exists more than one process each process is executed by
giving certain amount of time after that time control is
switched to next process and vice-versa.
Advantage:all process are executed simultaneously.
Disadvantage:it takes lot of time to execute all processes.

Answer / amitshiknis
Multitasking: The ability of an OS to do more then one
thing at atime. for instance, you can be downloading a
large file and still use another program to do something,
like write a book.
Multiuser: A computer system the can handle more then one
user at a time. Windows is not a multiuser OS. It can
handle only one user at a time.
Multiprocessing: The chip in new computers is able to do
more then one task at a time because there is more then one
processing unit on/in the chip.

Answer / akshita
1. multi-user: it implies that many users can work
simultaneously...every user working thinks that he is the
sole occupant of the computer resources but in reality every
user is alloted cpu time and other resources according to
cpu scheduling techniques ..and hence all computer resources
are shared by users working at same point of time..
2. multi-tasking: it implies that multiple tasks could be
performed simultaneously...for exammple:if u r working in
windows environment u access internet and u r also listening
songs..and u are working on some document also..
3. time sharing: in this method the cpu allocates every
user a very small time slice or time slot in
micromilliseconds...
when the time slot for a particular user
ends..the the cpu allots same time slot to next process..and
so on..in this way every proess is given time slice in a
circular fashion..

Answer / jatin khurana
multiprogramming-more than one program resides in the memory
& they are executed in interleaving fashion.CPU switches from one program to another if any I\O operation occurs, not fixed time allocated to each program
multitasking-logical extension of multiprogramming in which every job is executed for a given time slot & wait for its turn again so this generally uses the round robin scheduling
