- 3. ASSIGMENT#1 processor:- Cpu stand for central processing unit. Central processing unit is like the brain of the computer. The central processing unit (CPU) of a computer is a piece of hardware that carries out the instructions of a computer program. It performs the basic arithmetical, logical, and input/output operations of a computer system. 5/5/2018INFORMATION TECNOLOGY
- 5. ASSIGMENT#1 Component of cpu:- Control unit (CU). Arithmetic logic unit (ALU) . A number of register. 5/5/2018INFORMATION TECNOLOGY
- 6. ASSIGMENT#1 Control unit:- The control unit (CU) is a component of a computer's central processing unit(CPU) that directs the operation of the processor. It tells the computer's memory, arithmetic/logic unit and input and output devices how to respond to a program's instructions. 5/5/2018INFORMATION TECNOLOGY
- 7. ASSIGMENT#1 Arithmetic logic unit:- Abbreviation of arithmetic logic unit, the part of a computer that performs all arithmetic computations, such as addition and multiplication, and all comparison and logical decisions. 5/5/2018INFORMATION TECNOLOGY
- 8. ASSIGMENT#1 Register:- Processor register (CPU register) is one of a small set of data holding places that are part of the computer processor. A register may hold an instruction, a storage address, or any kind of data (such as a bit sequence or individual characters). Some instructions specify registers as part of the instruction. 5/5/2018INFORMATION TECNOLOGY
- 9. ASSIGMENT#1 How cpu works? The cpu is centrally located on the motherboard. Since the cpu carries out a large share of the work in the computer data pass continually through it. The data come from the ram and the units(keyboard, drives ,etc) after processing the data is sent back to the ram and the units. The cpu continually receives instructions to be executed. Each instruction is a data processing order. 5/5/2018INFORMATION TECNOLOGY
- 10. ASSIGMENT#1 Function of cpu:- For every instruction a processor repeats a set of four basic operations which are given following:- Decoding Fetching Executing Storing 5/5/2018INFORMATION TECNOLOGY
- 11. ASSIGMENT#1 Fetching:- Fetching is the process of obtaining a program or an application instruction or data from memory Decoding:- Decoding refers to the process of translating the instructions into signals the computer can execute. 5/5/2018INFORMATION TECNOLOGY
- 12. ASSIGMENT#1 Executing:- Execute calculation move data and jump to different addresses. Storing:- CPU dive some data after executing the instruction and store data being instructed. 5/5/2018INFORMATION TECNOLOGY
