Central Processing Unit (CPU)
A central processing unit (CPU), also known as the central processor, main processor, or simply processor, is the electronic circuit that executes the instructions composing a computer program.
Types of RAM
Examples of RAM include DRAM, SDRAM, DIMM, SO-DIMM, VRAM, and terms like DDR3 and GDDR5.
Components of a CPU
The CPU can be divided into three main components:
- Arithmetic Logic Unit (ALU)
- Control Unit (CU)
- Registers
The CPU comprises the RAM, registers, buses, ALU, and controller.
CPU Functions
The CPU executes the instructions of a computer program, performing basic math, logic, and input/output tasks for a computer system.
CPU Architectural Diagram
The computer system consists of blocks: Central Processing Unit (CPU), input devices, and output devices. The CPU is further divided into the Arithmetic Logic Unit (ALU) and the Control Unit (CU).
Types of CPUs
There are various types of CPUs available, including single-core, dual-core, quad-core, six-core, eight-core, and ten-core CPUs used in different devices like desktops, laptops, and cellphones.
