      TOSLINK

      TOSLINK or Toshiba – LINK is a connection standard for digital audio streams. It is a standard which uses fiber optic cables. The important feature of fiber optic cables is that they convert audio signals into light impulses as opposed to electric signals. TOSLINK cables usually transmit their signals as the red LED lights.

      Who Invented the Microphone?

      A microphone is a device that converts acoustic power into electric power. Both the acoustic power and the electric power have similar wave characteristics that convert sound waves into electric voltages that eventually convert back into sound waves through speakers. Microphone were used with the first telephones, and then with radio transmitters soon after. Sir

      Multi-Core Technology

      Multi-core technology is the term that describes today's processors that have two or more working processor chips (more commonly referred to as cores) working simultaneously as one system. Dual cores or chips with two processors that work as one system are the first type of multi-core technology applications. How It Works The multi-core processor technology

      EPROM (Erasable Programmable Read Only Memory)

      EPROM or Erasable Programmable Read Only Memory was invented by Engr. Dov Frohman. It is a ROM-type chip that can hold data from 10-20 years. It is different from PROM because it can be programmed more than once. An EPROM programming is erased only through exposure to ultra violet light. The EPROM is configured or
