We would like to thank Prof. Devendra Jha, who helped us explore Information Technology. Through this paper, we gained insight into the manufacture of the computers along with the materials used in it and also in the communication equipments.
The group would like to specially thank Mr. Arunav Dey (B.E, Electronics), Mr. Harsh Agarwal (B. Tech, E&I) and Mr. Ankur Gupta (B.E, ECE) for their guidance on certain aspects of the paper.
In the end, we would like to extend special thanks to each other for co-operating at every levels and making this project a success.

The innovation of computer has the most significant impact on human civilization than any other innovation of nineteenth century. In the beginning, computer was introduced mainly as a computing system. Solution of huge numerical problems with large number of variables became possible with the help of computer. Later, people started to use it for automation of process. Industrial production witnessed a huge growth in terms of quantity and quality as well. During the last half of nineteenth century the world discovered the potential of computer as a means of faster communication. Computer made it possible to exchange information in the fraction of a second. However, this advancement in communication would not have been possible by computer alone if there had not been subsequent development in the field of electronics. The basic function of computers in communication system is to process and transmit information in the form of electronic signals. These signals are the result of movement of electrons. Materials which are involved in generation and transmission of this signal are called electronic materials. Photons i.e. the constituent particles of light are also used in signal generation and transmission which is called optical signal. Materials used in producing optical signal are called photonic material. Obviously, photonics has increased the speed of data processing significantly. In this paper some features of the electronic materials and photonic materials have been discussed very briefly.
Semiconductors are materials which have a conductivity between conductors (generally metals) and nonconductors or insulators (such as most ceramics). Semiconductors can be pure elements, such as silicon or germanium,...
