What is processor in computer?
Computer processor is commonly known as central processing unit (CPU). It is the electronic motherboard or circuitry within a PC that transfers out the commands of a computer program by execution of some basic arithmetic, control, logical, control and input/output (I/O) operations stated by the commands. The term processor is used since from 1960s in the computer technology and generally the Central processing unit deals with the control unit and processing unit. CPU is unique with these core elements of the system from other components like input/output circuitry and main memory.
The design, form, and implementation of processors have been changed before the course of its history, but their important part of its operation rests almost unaffected. The main part of the CPU that include the arithmetic logic unit (ALU) which can does arithmetic and logic operations, that can support operands to the Arithmetic Logical Unit and can save the results of ALU operations. The control unit can allows to fetches commands from memory and implements them by important and coordinated with the registers, ALU, and other components of the computer.
Types of Processor:
The bandwidth of the light-based microprocessor which connects with predictable electronic circuitry whereas the optical computing is totally a new idea that is implemented by the researchers at University of Colorado-Boulder, California. Light based processor consists of in built photonic transmissions with single chip which can fit into traditional electronics, so this could be the theory work of standard electronic components and participate into present manufacturing processes. It is the initial processor which can be used to communicate with other device. And no other microprocessor or computer processor contain photonic input/output in the chip.
Light based on Processor:
The great benefit of light-based processor is that it is faster in sharing or transferring information within the given space, with the new chip hyping a thickness of 300 gigabits per second/square millimeter. That means 10 to 50 times much improved than any outdated electrical microprocessors. Light-based processors assured to be high energy efficient, as they can easily transfer information/data up to longer distances deprived of having more power.
The lab processor are not particularly powerful, as it designed with only two computing cores, but most of the processor researchers are eager it could be improved for networking chips, and can prove it is faster than any other processor. Therefore, at present light-based processor is the effective CPU for computers.
