Arithmetic logic unit, ALU: Within the central processing unit, the ALU performs arithmetic and logical operations.
Control unit, CU
: The Control Unit elements of the central processing unit extracts instructions from memory and decodes and executes them, and it uses the ALU where necessary.
What extracts instructions from memory and decodes and execute them?
- The arithmetic logic unit (ALU), which performs arithmetic and logical operations.
- The control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
What part of the CPU gets instructions from the memory?
The control unit fetches (gets)
the instruction from memory. The control unit decodes the instruction (decides what it means) and directs that the necessary data be moved from memory to the arithmetic/logic unit.
Which extracts instructions from memory and decodes and executes them calling on the ALU when necessary?
Two typical components of a CPU are: 1) the arithmetic logic unit (ALU), which performs arithmetic and logical operations, and 2)
the control unit
, which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
What computer component processes and executes instructions?
A central processing unit (CPU), also called a central processor, main processor or just processor
, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program.
What is Ram in memory?
Random access memory
(RAM) is a computer’s short-term memory, which it uses to handle all active tasks and apps.
What are the three basic steps in the instruction execution cycle?
It is composed of three main stages:
the fetch stage, the decode stage, and the execute stage
.
What are the 3 types of CPU?

- Dual-core CPU. …
- Quad-core CPU. …
- Hexa Core processors. …
- Octa-core processors. …
- Deca-core processor.
What is CPU explain with diagram?
A central processing unit (CPU) is the
electronic circuitry
within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.
What 3 things affect the speed of the CPU?
- clock speed.
- cache size.
- number of cores.
What are the two main components of computer?
- hardware includes the Physical features, which are every part that you can either see or touch, for example: monitor, case, keyboard, mouse, and printer.
- The part which activates the physical components cs alled software.
Which of the following are two main components of the CPU?
- Control unit and ALU are the two main components of the CPU.
- The two typical components of a CPU include the following: The arithmetic logic unit (ALU), which performs arithmetic and logical operations. …
- The Central Processing Unit (CPU) is also known as the microprocessor or processor.
What are the two parts of the CPU?
There are 2 parts of the CPU:
The ALU and Control Unit
. The Arithmetic Logic Unit (ALU) performs arithmetic operations (such as addition and subtraction) and logical operations (such as comparing two values). The Control Unit deciphers and carries out instructions.
Which is not included as main component of CPU?
Answer:
Primary Storage (RAM)
is not a part of CPU. CPU consists of Register (Memory Location), ALU and Control Unit.
What are the 4 components of a CPU?
- Arithmetic logic unit. The arithmetic logic unit (ALU) performs the arithmetic and logical functions that are the work of the computer. …
- Instruction register and pointer. …
- Cache. …
- Memory management unit. …
- CPU clock and control unit. …
- Random access memory (RAM) …
- Supercharging the instruction cycle. …
- Hyperthreading.
What are the two important components of CPU that help in processing the input into output?
Central processing units have two primary components:
the control unit that regulates the processor’s operation and the arithmetic logic unit
that actually crunches numbers and compares values.
