The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations. As long as most memory accesses are cached memory locations, the average latency of memory accesses will be closer to the cache latency than to the latency of main memory.
Thus Cache memory is not main memory of computer system.

Answer:- The Cache memory is placed between the CPU and the main memory. It is a fast speed memory and is expensive and faster than the main memory. Cache memory is used to store the frequently accessed data of main memory. The instructions that are frequently used by the CPU are stored in the cache memory. It is used to reduce the average access time for address, instructions or data, which are normally stored in the main memory. Cache memory increases the operating speed of the system. But is much costlier than main memory. From economic considerations, the capacity of the cache memory is much less as compared to main memory..
cache memory is neither main memory nor second memory. DDR's are Main memory and Disk is second memory.
Catch memory is internal memory to do the work it can stores the given input to the system
The purpose of the direct mapped cache tag in a computer system's memory management is to quickly determine if a requested memory address is stored in the cache memory. This helps improve the system's performance by reducing the time it takes to access data from the main memory.
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..
To calculate the cache miss rate in a computer system, you divide the number of cache misses by the total number of memory accesses. This gives you a percentage that represents how often the CPU needs to fetch data from main memory instead of the cache.
because cache memory is costlier than main memory and physical size of cache memory also matters.ignoring the cost , if we use large cache memory, it will take larger physical space.so mother board won't be able to accomodate it
A cache miss occurs when the CPU cannot find the needed data in the cache memory and has to retrieve it from the slower main memory. This impacts performance by causing a delay in processing instructions, as accessing main memory is slower than accessing the cache. This can lead to decreased overall system performance and efficiency.
The cache memory is used to store the frequently used data in the main memory in order to avoid the elapse of the seek time taken to read that data in the main memory.. So, to improve the performance of a PC, its necessary to have cache memory.
as the cache memory is mory faster than RAM or hard disk ,but the main reason is that the cache memory has comparator and storage medium at the same time, the comparator checks if the address of the value being accessed is in the associative memory(a part of cache)or not, and the ordinary memory(another part of cache)has the data....
If we took size of cache as large as size of main memory then the main purpose of cache(take less time) would come to end, as larger the cache slower would be it's processing speed.
The miss penalty in cache is calculated by determining the time it takes to access data from the main memory when a cache miss occurs. This time includes the latency of fetching the data from the main memory and loading it into the cache. The miss penalty is the additional time required when data is not found in the cache and needs to be retrieved from the main memory.
