What are the differences among direct mapping associative mapping and set associative mapping?

The differences among direct mapping and set-associative mapping :Direct mapping : Each line in main memory maps onto a single cache line.Set-associative : Each line in main memory maps onto a small (collection) set of cache line.Direct mapping : A memory block is mapped into a unique cache line, depending on the memory address of the respective block.Set-associative : A memory block is mapped into any of the line of a set. The set is determined by the memory address, but the line inside the set can be any one.dont knowyet

What is assosciative mapped cache?

An associative cache is a cache that has 1 or more extra slots for each place in memory. So if two pieces of memory map to the same place in cache, you can write both entries. In this case, you will need a cache replacement policy to determine which gets evicted first when it's full and new data arrives.

What are the advantages and diadvantages of a buffer cache?

A cache allows one to retrieve commonly used information very quickly (if it is still in the cache) rather than trying to find it on the system (which takes much longer). The disadvantage is that is takes away memory from the system to implement the cache.
