CPU (Central Processing Unit)
The brain of the computer responsible for fetching, decoding, and executing instructions.
CPU Functionality: Fetching, Decoding, Executing
(a) Fetching: Retrieves instructions from RAM. (b) Decoding: Interprets the instruction. (c) Executing: Carries out the operation.
Processor Cores
Cores are units within the CPU that execute instructions. Multi-core processors can handle multiple tasks at once, improving performance.
Single-Core vs. Multi-Core Processors
(a) Single-core: Handles one task at a time. (b) Multi-core: Handles multiple tasks simultaneously
CPU Architecture: 32-bit (x86) vs. 64-bit (x64)
(a) 32-bit (x86): Manages data in 32-bit chunks. (b) 64-bit (x64): Handles data in 64-bit chunks for better performance.
x86 and x64 Names
(a) x86: Originates from Intel’s 8086 processor, which evolved to 32-bit. (b) x64: Refers to 64-bit processors, capable of handling more data at once.
Operating System Compatibility
The OS must match the CPU architecture (32-bit or 64-bit) and have compatible drivers to function properly.
Advanced RISC Machine (ARM)
A CPU architecture known for efficiency in power consumption and heat generation. Ideal for mobile devices like smartphones and wearables.
Multithreading
A process where a CPU handles multiple threads (tasks) at once, improving performance in multitasking, gaming, and video editing.
Benefits of Multithreading
Improves responsiveness and efficiency by allowing the CPU to work on multiple tasks simultaneously, especially in multi-core CPUs.
Summary of CPU Architecture
The CPU's architecture affects performance and compatibility with operating systems and drivers. x86 (32-bit) and x64 (64-bit) are common, with ARM used for energy-efficient devices.
