The processor (CPU) is the main chip in a computer that performs all calculations and runs instructions.

These are important features that decide how fast a processor is.

A core is like a separate processing unit inside the CPU.

The difference is mainly in how much data the CPU can handle at once and how much RAM it supports.

Ask students to check the processor brand on their home computer.

Cache is very fast memory inside the CPU.

Cache stores frequently used instructions so the CPU does not waste time going to RAM.

F. Relationship between CPU, RAM, and Cache

RAM is much faster than SSD/HDD, but slower than cache.

Ask students to check CPU information on their computers:

Cache is very fast memory inside the CPU. There are three levels:
