What does L1 and L2 cache mean?
L1 is “level-1” cache memory, usually built onto the microprocessor chip itself. For example, the Intel MMX microprocessor comes with 32 thousand bytes of L1. L2 (that is, level-2) cache memory is on a separate chip (possibly on an expansion card) that can be accessed more quickly than the larger “main” memory.
What does L1 L2 and L3 cache mean?
The main difference between L1 L2 and L3 cache is that L1 cache is the fastest cache memory and L3 cache is the slowest cache memory while L2 cache is slower than L1 cache but faster than L3 cache. Cache is a fast memory in the computer. It holds frequently used data by the CPU.
