WRITTEN BY: SHAFAT TAHIR 23 MAY 2010

Today, the term information has blown up to include many aspects of computing and skill, and the term has become very identifiable. IT professionals perform a range of duties that range from installing applications to designing multifarious computer networks and information databases. A small number of the duties that IT professionals perform may include data management, networking, engineering computer hardware, database and software design, as well as the management and administration of entire systems. Information technology is opening to spread farther than the predictable personal computer and network technology, and more into integrations of other technologies such as the use of mobiles, televisions, automobiles, and much more, which is rising the demand for such jobs.

When computer and communications technologies are united, the result is information technology, or ?InfoTech?. Information technology is a common term that describes any technology that helps to produce, direct, store, communicate, and/or disseminate information.

In fresh days ABET and the ACM have collaborated to form certification and curriculum standards for degrees in Information Technology as a discrete field of study separate from both Computer Science and Information Systems. SIGITE is the ACM working group for defining these values. The Worldwide IT services revenue is $ 763 billion in 2009.COMPUTERSIt is playing an important role in the field of information and technology. As it is consider the most important & useful machine of 20th century. It computer is a programmable machine that receives input, stores and manipulates data, and provides output in a useful set-up.

HISTORYAlthough automatic examples of computers have existed through much of recorded human history, the first electronic computers were developed in the mid-20th century. These were the size of a large room, and were called 1st generation computers.They consuming as much power as several hundred modern personal computers (PCs). Modern computers or 4th generation computers are based on integrated circuits which are in millions to billions of times more capable than the early machines, and occupy a fraction of the space. Simple computers are small fit into small pocket devices, and can be powered by a small battery. Personal computers in their variety of forms are icons of the Information Age and are what most people think of as ?computers?. However, the entrenched computers found in many devices from MP3 players to fighter aircraft and from toys to industrial robots are the most numerous. MOBILE PHONESA mobile phone is an electronic device used for mobile telecommunications over a cellular system of base stations known as cell sites. Mobile phones vary from freestyle telephones, which only offer telephone service within partial range through a single base station attached to a set line, for example within a home or an office. Low-end mobile phones are often referred to as feature phones, whereas high-end mobile phones that offer more advanced computing capability are referred to as smart phones.

A mobile phone allows its users to make and receive telephone calls to and from the public telephone network which includes other mobiles and fixed line phones crosswise the world. A key feature of the cellular network is that it enables seamless telephone calls even when the user is moving around wide areas via a process known as handoff or handover.

In addition to being a telephone, modern mobile phones also support many additional services, and accessories, such as SMS (or text) messages, email, Internet access, gaming, Bluetooth, infrared, camera, MMS messaging, MP3 player, radio and GPS.
