1.Reason 1: caches are useful when two or more components need toexchange data, and the components perform transfers at different speeds. E.g., the CU registers and the disk are wo such components. Caches solve this problem byproviding a buffer of intermediate speed to store part of the data

1. Message passing models (Erlang, for example) do not have any shared state; all synchronization and communication is done by exchanging messages. Shared memory models communicate by reading/writing to shared memory blocks, which are protected by semaphores or similar. Message passing's pro
