Answer:
Register-it contains all the instructions that are present in the processor.
Memory location- it is the particular memory address where the data is stored.
Explanation: Difference between register and memory location are as follows :-
- Register are the found in the CPU internal storage and memory location is present on the RAM.
- Registers are faster in movement as compared to the memory location.
- Register has the capacity of holding of less data as compared to the memory location which can store data in large amount .
Disk access is way slower than
memory access. Caching is a technique to improve the disk access time. Block cache is a caching technique which
reduces disk accesses time. Here a
portion of disk is bought to cache for reading and a modified blocks are first
changed in cache but reflected in the disk at one go. On the other hand with write through caching
each modified block is written to cache and at the same time it is written to
the disk. Write- through caching
requires more disk I/O so they can have a negative effect on the performance.
