Introduction of processor ۩ Integrated circuit ۩ Controls all of the system components ۩ Execute computer programs ۩ Processor is also called brain of the computer ۩ Operation and Instruction in processor

Use of heat sink and fan in processor  Silver metal strips on the side of the processor  Draw heat away from the processor  Prevent processor from overheating and melting

Registers and its type Local memory location where data is temporarily stored. Overall number of registers can vary depending upon the types of processor. The main registers:- 1) Accumulator register: Stores the result of arithmetic and logical operations 2) Status register: Holds system status indicator 3) Instruction register: Contains the current instruction being processed

4) Ordinal counter: Contains the address of the next instruction to process 5) Buffer register: Temporarily stores data from the memory

Functional Units Processor is made up of group of interrelated units. Types of units:- 1) Control unit: Controls the flow of data. Gets its instruction in the form of code. Translate the code. 2) Arithmetic and logical unit: Handles all the mathematical calculations. Performs logical comparisons. Takes command from control unit. Performs them and store in the memory.

Cache Memory Reduces waiting times for information stored in the RAM. Have greatly increased cost. Temporarily store the primary data to be processed. Types of Cache memory:- 1)Level one cache memory 2)Level two cache memory 3)Level three cache memory

Technology Improvements 1) Parallel Processing: Simultaneous use of more than one processor. Makes program run faster. 2) Multi Processing: Simultaneous use of more than one processor or computer. Computers are joined by high speed channel to share the workload. 3) Hyper Threading: Placing of two logic processor with a physical processor. Multitasking system.

Factors affecting the performance of processor Θ Clock Speed Θ Speed of internal bus, address bus, data bus Θ Amount of RAM Θ Cache memory Θ Multi Processing

Conclusion Thus, it is one of the most important and amazing parts of the PC, and also the most amazing devices in the world of technology. All work that we do on our computer is performed directly or indirectly by the processor.
