WHAT IS A MICROPROCESSOR

A microprocessor is an integrated circuit on a tiny silicon chip that contains thousands or millions of tiny on/off switches, known as transistors. The transistors are laid out along microscopic lines made of superfine traces of aluminum that store or manipulate data. These circuits manipulate data in certain patterns, patterns that can be programmed by software to make machines do many useful tasks.

THIS IS A MICROPROCESSOR!

how does it work

A microprocessor is the central processing unit in a computer. It receives, transmits and coordinates every command and process carried out by the system. Electrical currents, moving through wires and transistors, are converted into usable messages through the use of a Boolean logic language. Based on the "on/off" frequency of current moving through transistor circuits, this Boolean logic communicates system commands to and from receiving devices within the computer. The microprocessor communicates within two primary capacities: logic and the processing of information. These processes are handled by two components within the chip:
*Arithmetic logic unit (ALU), responsible for all commands requiring an arithmetic or logic function
* Control unit (CU), which handles the information processing from the computer's memory

Speed of Microprocessor

The speed of microprocessor depends on various factors, such as the number of instructions it processes, the bandwidth, and the clock speed. An instruction is a command that the Microprocessor executes. The bandwidth identifies the number of binary digits that the Microprocessor can proceed in a on its own order. The clock speed identifies the speed at which the microprocessor processes an instruction

in November, 1971, a company called intel publicly introduced the world's first single chip microprocessor, the Intel 4004.
