Fiber optic cable is a communication medium made of glass or plastic that can transmite signals in the form of light. In optics there is a principle which states that when a beam of light travels from denser medium to rerer medium then it deviates away from the normal drawn at the point of incidence at the junction of the two media. If the angle of incidence is such that the angle of refraction is…"Fiber Optics cable used in Guided Media of transmission."
Bus is an electrical way through which the processor communicates with the internal and external devices. Buses are assemble with the computer. Bus transfer data between the computer sub-system. It sends instructions and commands to and from the processor. It connects all internal computer peripherals devices which can easily communicate with the CPU. There are mainly three types of buses. 1. Address bus …"Buses and Activities of Bus or Buses in Computer System"
