Laptop is a personal computer. The size of the laptop is very small. The laptop contains all the components like keyboard, mouse, display, web camera, Bluetooth, wireless network etc. The laptop can carry while traveling time. The battery backup was available in laptop up to 3 hours. The first laptop was introduced by the IBM in the year 1973. It is like desktop computers all the desktop parts are in laptop but in small size. There are many advantages are available in laptop comparing to desktop. The main advantage it’s usable in the traveling time. Nowadays laptop plays an important role in many organizations. The sale of laptop is widely increased in all over the world. There are many laptop providers available such as HP, SONY, COMPAQ, APPLE, ACER, DELL, SAMSUNG etc.

Modern world invented so many useful things with difficulties. A computer is an example for the kind of device. It is used for so many applications and number of scientific research centres. Which is very essential one but also it has difficulties too. A virus is most dangerous one in the computer. It is small program coding which is created by programmers. A virus has different forms like malware, adware, and spyware programs. Most of the hackers creating malware programs and they are spread in some applications. Virus has reproductive ability so it will spread in computer files and destroy the all files. It cannot easily detect by computer suddenly. We have to install the antivirus software in computer. This Software can detect the virus and remove from the computer.

The wireless keypad was the most successful version because without wire it can connect computer directly. The wireless keypad works up to 3 meters radius of the base station that is computer. The wireless keypad was contained the two connections such as USB and PS/2 connection. The wireless keypad contains ordinary keys and multimedia keys. The wireless mouse also same as wireless keypad. It can directly connect to the computer without wire. The Gamepad was designed for the game lovers. There are different types of games are available for playing. The main advantage of the gamepad is it is more comfortable for playing game in computer. Most of the children’s like to play computers game through gamepad. The above three things are more popular comparing to the other.

With the advent of mobile technology in place, one has to think the very possibility of doing things on the move. You can’t imagine how fast the technology has developed in the means of mobile technology support. One can very well imagine how tough the scientists have worked to reach the peak level of mobile computer technology which we enjoy today. One can easily find a best way to cash your cheque. Many find this above said thing a very difficult one to manage because of their hectic work schedule. The Cheque deposit can be accomplished just by having a camera mobile in hand. The application will be able to send them image to the particular bank branch if they allow the service.

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.

The most important type of system software is the operating system. An operating system is an integrated set of specialized programs that is used to manage the overall operations of a computer. It acts like an interface between the user, computer hardware and software. Every computer must have an operating system to run other programs. DOS (Disk Operating System), UNIX, Linux and Windows are some of the common operating systems. The compiler software translates the source program (user written program) into an object program (binary form). Specific compilers are available for computer programming languages like FORTRAN, COBOL, C, and C++ etc. The utility programs support the computer for specific tasks like file copying, sorting, linking an object program, etc. the operating system is the important one for all computers.
