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
Multiprogramming is a rudimentary form of parallel processing in which several programs are run at the same time on a uniprocessor.Since there is only one processor, there can be no true simultaneous execution of different programs. Instead, the operating system executes part of one program, then part of another, and so on. To the user it appears that all programs are executing at the same time. Multitasking, in an operating system, is allowing a user to perform more than one computer task (such as the operation of an application program) at a time. The operating system is able to keep track of where you are in these tasks and go from one to the other without losing information Multithreading is the ability of a program or an operating system process to manage its use by more than one user at a time and to even manage multiple requests by the same user without having to have multiple copies of the program running in the computer
The two concepts build upon each other. A single tasking (ST) operating system is necessarily a single user (SU) operating system, but a single user operating system may be a multi-tasking (MT) operating system. For example, MS-DOS is a SU, ST operating system (there was only one "user" and only one program could run at a time), Microsoft Windows 3.1 was a SU, MT operating system (only one user could be logged in at a time, but multiple tasks could run at once), and Windows XP is a multiple user (MU), MT system, as multiple users could be logged in at once, and multiple tasks could be run at once. There is no known example of a MU, ST operating system.
A multithreaded program is one that has multiple threads in execution. They may execute parallel to one another or totally without relation to one another. In Java you can create multithreaded programs using Java threads.
Only one user is allowed to work on this type of operating systems.
Doing more than one thing at once. For instance: washing some dishes while your food is in the oven.
Multitasking is the word used for the execution of multiple tasks at one time.
In computing this would be called "parallel processing" or "multithreading."
Serial execution is when tasks are completed consecutively (one after the other), as opposed to concurrently (at the same time, in parallel).
It means to have ability to do multiple tasks at one time, meaning running various tasks or operations in parallel with each other at same time.
Yes, the execution of a task can be reduced by using multiple processors. Using more than one processor helps speed up a task.

First of all there is difference between program and a task. There may be multiple tasks running related to one program at the same time. so if the processor is busy in multiple tasks related to one program then it is multitasking. But if the multiple tasks which the processor is executing concurrently are related to different independent programs then the concept is know as multiprogramming.

Concurrent Execution in DBMSDatabase Management systems usually allow multiple transaction to run concurrently even though it causes a lot of complications with consistency of data. Ensuring consistency when multiple transactions execute concurrently, requires extra effort. It is much simpler to allow only one transaction to run at a time but concurrent execution of transactions has its own advantages: Improved throughput and resource utilization :Concurrent execution means that CPU doesn't have to be idle while it is waiting for I/O activity to complete. This is because transactions can run in parallel on CPU along with I/O activities. This means that resources can be utilized effectively by having multiple transaction run concurrently.Less waiting time : Without concurrency, a short transaction might need to wait for a long transaction to finish causing delay in its execution. With multiple transactions running on the system, new transactions have to wait for less time before getting executed.
Time management has several objectives. One is to reduce the amount of time one spends on trivial tasks. Another is to increase the effectiveness of time spent on essential tasks. A third is to balance one's time so that one does not undergo burnout.
Super computers are complex machines generally consisting of multiple computers or processor subsystems clustered or connected together to perform super computing tasks which need execution of many billions of instructions in a second. These are too complex for any one to be a able to draw a circuit or schematic of a super computer.
