Direct mappingA given Main Memory block can be mapped to one and only one Cache Memory line.It is Simple, Inexpensive, fastIt lacks mapping flexibilityAssociative mappingA block in the Main Memory can be mapped to any line in the Cache Memory available (not already occupied)It is slow, expensiveIt has mapping flexibility
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

There are different type of cache memory: processor cache memory, cache memory ram,1 cache memory l2, cache memory, CPU cache memory, disk cache memory, hard disk cache, cache memory motherboard.
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.
Yes. Now do your assignment yourself like everyone else.

Three types of mapping procedures are there? (1) Associative Mapping-The fastest and most flexible cache organizations uses associative mapping. The associative memory stores both the address and content of memory word. This permits any location in catche to store word in main memory. (2) Direct Mapping-Associative memories are expesive compared to RAM's because of added logic associated with each cell. (3) Set Associative Mapping-It is a more general method that includes pure associative and direct mapping as special case. It is an improvement over the direct mapping organization in that each word of cache can store two or more words of memory under the same index address. Each data word is stored together with its tag and the number of tag data items in one word of cache is said to form a set. With Regards Veer Thakur Chandigarh
Register memory are smaller in size than cache memory and registers are faster than cache..Cache memory store the frequently used data from main memory..
