The CPU bits are determined by the bit-size of the processor registers, address buses and data buses. 64-bit CPUs provide better performance than 32-bit ones, which on their part perform better than 16-bit processors.
The instruction set architecture (ISA) is a set of commands used by the software to manage the CPU’s work. Information about the set of instructions the processor can execute.
The cache memory is used by the processor in order to shorten the time needed to access data and instructions that a frequently used. The L1 (level 1) cache memory has a small volume, but operates faster than the RAM and the rest cache memory levels. If the processor does not find the data needed in L1, it continues to look for it in the L2 cache memory. In some processors the search in L1 and L2 is simultaneous.
The L2 (level 2) cache memory is slower than L1, but has a larger capacity, instead, which allows it to cache more data. Just like L1, it is much faster than the system memory (RAM). If the CPU does not find the data needed in L2, it proceeds to look for them in the L3 cache memory (if there is such) or in the RAM.
