Processor
- the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the computer's functions.
- it is also called as the brain of the computer
- it is also called as the brain of the computer
Basic Parts of the Processor
1. ALU (Arithmetic and Logical unit) - unit of the CPU is responsible for performing arithmetic and logical operations. This unit of the CPU gets data from the computer memory and perform arithmetic and logical operations on it. The arithmetic unit of ALU performs arithmetic operations like addition, multiplication, subtraction and division. The Logical unit of ALU performs logical operations such as comparison of two numbers. It tells us which number is greater and which is smaller. The common comparisons such as less than, equal to, or greater than are performed by the logical unit.
2. Memory Unit: A processor has its own memory inside it in the shape of small cells. Each memory cell is called a "Register". Registers are used to carry data temporarily for performing operations. There are total 13 registers in a processor. ALU gets data from registers and stores it in registers to perform arithmetic and logical operations. And data comes in registers from main memory of the computer.
3. Control Unit: This unit of the processor controls all the activities of the processor and also controls the input and output devices of the computer. It acts just like a police inspector who controls the traffic on a road. The control unit controls the whole traffic of the computer. It tells the input device that it is now his turn to feed data in the computer and show result of data after execution on the output units. This unit also controls the flow of instructions, which are given to a computer. It obtains instructions from the program stored in main memory, interprets (translation of instructions into computer language) the instructions, and issues signals that cause other units of the computer to execute them.

Types of Processor According to Socket
1. Land Grid Array (LGA) -a type of processor which do not have pins. It is a type of processor that was released by Intel . They first released the LGA 775 and few years they released the LGA 1156, LGA 1366 and the latest Intel Sandy Bridge processors which has the socket of LGA 1155.
2. Pin Grid Array (PGA) - a type of processor which usually has pins. It is used by older Intel processor and AMD processors.
Processor Manufactures
1. INTEL - (Integrated Electronics) -a multinational semiconductor company which was founded in 1968 . They are the one who created the world's first commercial microprocessor chip in 1971.
Intel was originally known primarily to engineers and technologists, its "Intel Inside" advertising campaign of the 1990s made it and its Pentium processor household names.
