What is a CPU core?
A core is an individual processing unit within a CPU that can independently fetch, decode, and execute instructions.
What are the main components of a core?
Instruction logic, Arithmetic Logic Unit (ALU), Control Unit, Registers, Load/Store logic, and L1 cache.
What is a multicore processor?
A single CPU chip that contains two or more independent cores.
How does a core compare to a full CPU?
A single core performs like a CPU; a multicore CPU has multiple cores on one chip working together.
Why use multicore processors?
Improves multitasking, performance, and power efficiency.
How does cache relate to cores?
Each core has its own small, fast L1 cache, often L2 as well, while L3 cache is usually shared between all cores.
Example of a multicore processor?
Intel Core i7/i9 or AMD Ryzen CPUs, with 4, 8, or more cores.
