Introduction
The world now becomes a global village, a number of things are now changed as they were in past decades. Computer and information technology has bought a number of changes in the computer field. Due to rapid growth in information technology, there is a need to educate students about this field. ICT is a subject in education countries like the Philippines has also ICT as an educational subject in the United States, the ICT program is linked and sponsored by Becta, and a recent scheme of online education has been introduced in order to educate students in schools. A number of schools also uses ICT to enhance capabilities and skills of learning and teaching.
Moore’s law
Moore’s law describes the historical trend in computer hardware. This law was first published in 1965 by Gordon E.Moore. Moore’s law deals with capabilities and features of almost every component of computer hardware, i.e. processing speed, memory capacities and pixel arrangements in digital cameras. The trend of using digital devices for the betterment of the economy has become very common, Moore’s law deals with the driving force of computer technology in the late 20& 21 centuries. Moore’s Law deals with a number of transistors in a most complex chip, density at minimum cost per transistor, performance per unit cost, power consumption, Ram storage capacity etc. The computer industry believes that Moore’s law is the most successful observation till now, and it will work for centuries by doubling the time used in calculations. There are some limitations of Moore’s law about transistor size and speed. Moore’s law uses an integration of digital components in wireless, optical technology and sensor-based systems.
Metcalfe’s law
Metcalfe’s technology links computer systems and uses a mathematical formula for calculating the value of communication networks. It deals with communication between networks; it states the value of a communication network is directly proportional to the square of the number of connected users on the system. This law deals with the values and network effects of the internet, social networking and the World Wide Web. Mathematically it is expressed as n (n-1)/2. The best example of this law is a fax machine, a single fax machine is useless, but the addition of every single fax machine in the network adds value to the network and also increases its capabilities.
Communication
Communication is a trend of transmitting messages, documents from sender to receiver. Computer hardware plays an important role in communication. Over recent years, the need for communication over the network has increased a lot, and the number of hardware is specially designed keeping in mind communication and network needs.
Historical
The history of ICT has faced a number of challenges and unique trends in past decades. Martin Collins and Janet Abate retraced the historical context of the development of ICT in different dimensions in the post-war era (Jannet, 1978). In the early period, nobody knew the processing speed, cost over the unit, performance issues which created a lot of problems; with the passage of time number of scholars endorsed efforts in this domain and now its fast-growing field in the world.
Present Situation
In the UK, computer simulation systems based on ICT are working in different fields (Dera, 2001). In Malaysia, the online business portal is one of the best inventions based on ICT; in Australia, a number of monitoring systems are specially designed, keeping in mind the basics of ICT and Moors law. In underdeveloped countries, a number of applications based on ICT and Moore’s law (1965) are working in different domains. Anecdotal evidence proves that there is a wide room for improvement in ICT, education and communication.
Future
At a glance, ICT has now become an important aspect of communication over the network. In 2028, this field will grow a lot and will reduce long distances via networks. Considering the future of ICT, there is no shortage of information and material. In upcoming years, wireless will become more important with the mobility of services, devices and people. Devices will evolve from independent and analogue to connected digital devices; there will be a tremendous increase of ICT in medicine, increase in the use of artificial intelligence, use of nanotechnology will increase, use of more robust and renewable materials will increase. ICT has a very bright growth in upcoming years, and it will change the shape of the world in 21 century.
