Types of Cache momery

1: It is the primary degree of reserve memory, which is called Level 1 store or L1 store. In this sort of store memory, a limited quantity of memory is available inside the computer processor itself. On the off chance that a computer processor has four centers (quad center computer chip), each center will have its own level 1 store. As this memory is available in the computer processor, it can work at a similar speed as of the computer processor. The size of this memory goes from 2KB to 64 KB. The L1 reserve further has two kinds of stores: Guidance reserve, which stores directions expected by the central processor, and the information store that stores the information expected by the computer chip.

2: This reserve is known as Level 2 store or L2 reserve. This level 2 store might be inside the central processor or outside the computer chip. Every one of the centers of a computer processor can have their own different level 2 reserve, or they can share one L2 store among themselves. On the off chance that it is outside the computer processor, it is associated with the computer processor with an exceptionally fast transport. The memory size of this reserve is in the scope of 256 KB to the 512 KB. As far as speed, they are more slow than the L1 store.

3: It is known as Level 3 reserve or L3 store. This store is absent in every one of the processors; some very good quality processors might have this sort of reserve. This store is utilized to upgrade the presentation of Level 1 and Level 2 reserve. It is situated external the computer chip and is shared by every one of the centers of a central processor. Its memory size goes from 1 MB to 8 MB. In spite of the fact that it is more slow than L1 and L2 reserve, it is quicker than Arbitrary Access Memory (Smash).
