The cache memory is divided into levels. Their number in modern processors can reach up to 3. The memory of the first level L1 is the fastest. To optimize information processing, the L1 cache may be divided into data cache L1 D-Cache and cache instructions (commands) L1 I-Cache.
Second level cache the L2 has lower performance and greater volume. In older computers it is a separate chip on the motherboard. The cache memory of the third level is the slowest, although it is much faster operational memory. The volume of L3 can be 24 Mb.
To see the properties of the cache can also use the program Everest. Run the program and expand the "motherboard". Double-click on "CPU". In the right part of the window under "CPU Properties" you will see the options of different levels of cache memory.
