What is an Operating System?

An Operating System(OS) is a program designed to run other programs on a computer. A computer’s operating system is its most important program. It is considered the backbone of a computer, managing both software and hardware resources. Operating systems are responsible for everything from the control and allocation of memory to recognizing input from external devices and transmitting output to computer displays. They also manage files on computer hard drives and control peripherals, like printers and scanners.

The operating system of a large computer system has even more work to do. Such operating systems monitor different programs and users, making sure everything runs smoothly, without interference, despite the fact that numerous devices and programs are used simultaneously. An operating system also has a vital role to play in security. Its job includes preventing unauthorized users from accessing the computer system.

RIM, which is known for its BlackBerry series of phones, had introduced PlayBook in June in the Indian market.

According to analysts, sales in the tablet PC segment in India are expected to touch one million units over the next 12 months. With 3G (high-speed internet services) being rolled out aggressively, the opportunity has only expanded, they said.

Since the launch of Apple's iPad in the country, the tablet market has been witnessing huge competition, with more and more new contenders launching their devices.
