Things are changing rapidly as the world is progressing. In this modern world people are using advanced machines to do their work. Computer is the most advanced machine that people use to do their work. This particular machine is used in every field of life. Advanced techniques are used with help of computers to diagnose dangerous diseases. Advanced manufacturing techniques are used with the help of computers to manufacture the products. Computers are extensively used in the field of engineering.
In past one machine was used to perform only a single task but now-a-days with the help of computers you can perform different tasks at one time. In modern business environment computers have special importance. A huge amount of time is saved due to multitasking. In business terms time is money, so if you are saving time you are saving money as well. Due to multitasking the costs of businesses have reduced.
What is the meaning of multitasking? It means that running several programs simultaneously. Since modern computers typically execute instructions several orders of magnitude faster than human perception, it may appear that many programs are running at the same time even though only one is ever executing in any given instant. Multitasking may slow down a computer that is running several programs at one time.
Many advanced computers are designed to share their work across many CPUs. This process is called multiprocessing. This technique is generally used in powerful computers such as super computers, mainframe computers and serves.
Thus, the entire world is fully dependent on computers. Due to this factor demand of computers has been increased.
