MICROPROCESSORS
The computer you are using to read this page uses a microprocessor to do its work. The microprocessor is the heart of any normal computer, whether it is a desktop machine, a server or a laptop. The microprocessor you are using might be a Pentium, a K6, a PowerPC, a Sparc or any of the many other brands and types of microprocessors, but they all do approximately the same thing in approximately the same way.
A microprocessor -- also known as a CPU or central processing unit -- is a complete computation engine that is fabricated on a single chip. The first microprocessor was the Intel 4004, introduced in 1971. The 4004 was not very powerful -- all it could do was add and subtract, and it could only do that 4 bitsat a time. But it was amazing that everything was on one chip. Prior to the 4004, engineers built computers either from collections of chips or from discrete components (transistors wired one at a time). The 4004 powered one of the first portable electronic calculators.
Microprocessor is a controlling unit of a micro-computer, fabricated on a small chip capable of performing ALU (Arithmetic Logical Unit) operations and communicating with the other devices connected to it.
Microprocessor consists of an ALU, register array, and a control unit. ALU performs arithmetical and logical operations on the data received from the memory or an input device. Register array consists of registers identified by letters like B, C, D, E, H, L and accumulator. The control unit controls the flow of data and instructions within the computer.

Features of a Microprocessor
Here is a list of some of the most prominent features of any microprocessor −
Here is a list of some of the most prominent features of any microprocessor −
- Cost-effective − The microprocessor chips are available at low prices and results its low cost.
- Size − The microprocessor is of small size chip, hence is portable.
- Low Power Consumption − Microprocessors are manufactured by using metaloxide semiconductor technology, which has low power consumption.
- Versatility − The microprocessors are versatile as we can use the same chip in a number of applications by configuring the software program.
- Reliability − The failure rate of an IC in microprocessors is very low, hence it is reliable.
