Optical Fiber Optical fiber is a type of dielectric (insulating) material, such as glass or plastic, capable of transporting light. High-speed data can be transmitted through optical fibers by total internal reflection of light. The biggest feature of optical fiber is that it transmits light signals instead of electrical signals. Currently available optical fibers have …

Use of integrated circuits (IC) started the third generation of computer. IC reduced the size, price, use of electricity etc. IC also facilitates speed and reliability of computers. Development of IC enabled organizing the whole central processing unit in single chip. Use of monitor also started in this generation. Operating system was improved to a new level and high speed line printers were in use. Followings are some of the characteristics of third generation.
Data communication systems enable transfer of data using one of the three transmission modes. Data communication systems has 4 fundamental characteristics; which are delivery, accuracy, timeliness and jitter.
Computer became very popular and more important part, unavoidable device of today’s world because of its characteristic like correct and dependable outputs, high speed, accuracy etc.
