My sincere advice is to use any pocket computer to enjoy the benefits of handy computing. The advent of pocket computing has become very much useful in the recent times. The very example of comfort one can get from the handy computing is that you will get the advantage of taking your virtual world with you. For example, the advent of recent technology is to such an extent that you can take a photo of a real world entity even with the gestures of your hand. Just by framing the particular picture with your hand, you can simply get the picture from the real world. The most important thing to be noted here is that you can change the particular picture which you took on that particular day and edit it accordingly.

Any Operating system should be easy to use. Now-a-days people are hard pressed for time, so they cannot undergo any training for making use of the Operating System. The idea of using facilities available in the Operating System should be intuitive. The Operating System should allow developing application programs easier. Otherwise people cannot concentrate on the application development; instead, they have to spend lot of time in concentrating on the peculiarities of the Operating System. The Operating System should be portable. That is, the Operating System should run in almost all hardware platforms. There is a new version of the Operating System available. The Operating System acts as the manager of resources such as CPU time, memory space, file storage, I/O devices. Since there may be many conflicting requests, Operating System allocates resources in an optimal manner. That is, Operating System allocates resources in such a manner so as to achieve the maximum best possible result.

The Operating System also provides the means for the proper use of hardware, software and data in the operation of the computer system. The Operating System is like a supervisor in a company providing an excellent environment in which the other people can perform useful work. Operating System assumes yet another responsibility, that of serving as a control program. A control program controls the execution of user programs to prevent errors and improper use of the computer. It is especially concerned with the operation and control I/O devices. It is hard to define Operating System. There are several definitions for Operating System. One of the definitions is that Operating System is one program running at all times on the computer. The somewhat more widely accepted definition is that an Operating System is an interface between the user and hardware. The Operating System’s goals are to
1) Execute user programs in a user-friendly atmosphere.
2) Make the computer system convenient to use.
3) Optimize computer hardware.

If an average person is asked to explain the activities that happen inside the brain, he/she will not dare to even open his eyes. The brain provides a convenient highly sophisticated abstraction. It merely provides the image of an object without letting people know about the activities that happen inside the brain. In this case eye is an interface between the object and the part of the brain that processes visual data. In a similar fashion the Operating System hides from a person know the complexity of the hardware and allow the user to use the name of the files for reading and writing. The Operating System adds extended capabilities to a machine with which it is easier to program than the underlying hardware. The Operating System manages the resource. Modern computers are highly complex machines. They get more complex day by day. So it is very difficult to manage such a complex system but the Operating System manages the complex system in an efficient way.

The Operating System comes under the System Software category. The actual work is undertaken only by the hardware. In order to do useful work on a computer, one has to access the hardware, but one can access the hardware directly, only in the first generation computers. In the subsequent generations of computers direct access is denied. The architecture of the computers at the machine level is primitive and very hard to program. What is the reason for the denial of the access? If the access is not denied, unless the user is hard working, one of the two alternatives can happen.

1) The user may be forced to conclude that computer is not for him/her.

2) The user may damage the computer hardware.
