What is a processor?

Processor is to interpret and implement directives features. ADD STORE
LOAD.
Each processor has a unique, such as ADD, STORE or LOAD operation of such sets, this operation is to set the processor instruction set.
Computer systems designers used to the computer as the machine, so the instruction is sometimes referred to as the machine instruction set, and write their language is called the binary machine language.BASIC PASCAL Note, do not command processor system and BASIC or PASCAL such advanced programming language in the instructions confused. Instruction from the operation code and operand of the operation code specified in the operation to complete the function of the operands that the object of the operation. For example, a number of instructions to complete the sum of the two operations, it must know: (1) What is the number of these two? (2) Where the number of these two? When both the number stored in the computer memory when should have specified the location of the address, so that if the operands are the data in computer memory, the operand address is called. Processor's job is to find from the memory instructions and operands and to implement each operation, the completion of these tasks after the notice sent under an instruction memory. Processor at an alarming rate over again and again to repeat this step by step operation. A clock timer, called the issue of accurate timing signals, the signal processor to provide a regular pulse. (MHz) Measuring the speed of computer terminology from the field of electronic engineering, called megahertz (MHz), MHz means one million cycles per second. 8MHz8 For example, a common clock ticks per second, while at 8MHz processor, the computer's clock is ticking by 8 million. Processors by the two functional components (control logic components and parts count) and a group known as the register space composed of the special job.
