In the late 1940's scientists developed the first machines that could store and use encoded instructions or programs. In the beginning the users performing a variety of computations had to rewrite the basic hardware of the computers. Later on the innovations dramatically changed and increased the flexibility and usefulness of computers. Instead, they could simply direct the computer to perform one of the functions that it had stored in its memory.



As computers grew more powerful and the tasks they performed grew more complex, computer experts and scientists developed more complex sets of instructions that are executed automatically by the computers.

Advances in computer technology have made greater efficiencies of processing possible with out the need of manual operators. Most modern computers, particularly the personal computers are made and developed in a manner that they serve general purpose and that feature a high degree of programming flexibility.

As the computer technology has many diversified sub fields there are different roles defined for different sets of action and activities which cover the core technology of computing. The task of adapting an application program designed to run on one operating system to another computer system is often technically complex, and costly.

In recent years, software developers have developed programs to allow users to move files from one application program to another. Still the problem of compatibility between applications, programs and operating systems remains a major concern in the computer technology and software industry.

The major boost to the Information technology was due to the ever growing popularity of internet utility, which with the help of interactive support of web browsing really encompasses every aspect of toady's life. Internet has gained such a positive boost and response in the modern day living that almost every thing seems related to it. The new television services and high dimension video, audio facilities are giving it more popularity with the common people.

The computer technology is proving as a necessity in the coming years and surely is one of the great means of entertainment; a single magical box which has almost every available communication service contained in it.

The web has become a mass media phenomenon. With the development of web browsers the personal computers have gained the ability to access a sea of information on the web from the millions of websites. Internet has become a transaction medium for most electronic commerce and it is one emerging field which has lot of potential. It gives the users a lot of freedom and convenience in making transactions with various vendors from the safety of their homes or offices.

Computer technology has created a lot of job openings for professionals as well as non technical people; free lance web portals are also very well known and active contributors in providing experts and required workforce to the relevant fields from across the globe.

The technological change in the field of computers is helping the mankind in many ways; starting from the basic household to the technical levels of expertise, the computer technology is really covering all the aspects. The prompt access to information pertaining to any field or subject is now in the reach of average person due to the popularity and the user friendly nature of the internet.
