Explain the difference between direct-mapped and fully associative cache.
Direct-mapped cache is faster than fully associative cache due to its complex mapping system.
Direct-mapped cache has a one-to-one mapping of memory blocks to cache lines, while fully associative cache allows any memory block to be placed in any cache line.
Direct-mapped cache can store multiple memory blocks in one cache line, while fully associative cache has fixed mapping.
Direct-mapped cache allows any memory block to be placed in any cache line, while fully associative cache has a one-to-one mapping.
What is cache memory mapping?
Cache memory mapping is the technique of linking main memory addresses to cache memory locations.
Cache memory mapping is the process of storing data in secondary storage.
Cache memory mapping is the method of compressing files for faster access.
Cache memory mapping refers to the organization of data in hard drives.
What role does cache memory play in computer architecture?
Cache memory is used solely for graphics processing tasks.
Cache memory improves processing speed by storing frequently accessed data and instructions for quick retrieval.
Cache memory stores all data permanently for future use.
Cache memory reduces the overall memory size of a computer system.
How does cache mapping affect system performance?
Cache mapping is irrelevant to data storage efficiency.
Cache mapping has no impact on system performance.
Cache mapping affects system performance by influencing hit rates and data access speed.
Cache mapping only affects power consumption.
Describe the concept of cache hit and cache miss.
Cache hit: data found in cache; Cache miss: data not found in cache.
Cache hit: data stored in memory; Cache miss: data retrieved from disk.
Cache hit: data accessed quickly; Cache miss: data lost during retrieval.
Cache hit: data processed successfully; Cache miss: data corrupted during transfer.
What is the purpose of a cache line?
The purpose of a cache line is to compress data for storage efficiency.
The purpose of a cache line is to store data permanently in memory.
The purpose of a cache line is to manage network traffic between devices.
The purpose of a cache line is to optimize data access speed by storing blocks of data in the cache.
How does the size of cache memory impact data retrieval speed?
A smaller cache size increases data retrieval speed by storing more data.
A larger cache size improves data retrieval speed by reducing access time to frequently used data.
Increasing cache size slows down data retrieval due to more data to sift through.
Cache memory size has no effect on data retrieval speed at all.
What are the advantages of using cache memory?
The advantages of using cache memory include faster data access, reduced latency, improved overall system performance, and efficient use of CPU resources.
Limited storage capacity and accessibility
Increased power consumption and heat generation
Slower data retrieval and processing times
The effectiveness of cache memory is primarily based on which property of programs?
Locality of reference
memory localisation
random access nature
memory size
Which type of locality aims at designing a cache to store recently referenced data, assuming that the same data will be requested frequently again soon?
Only Spatial Locality
Only Temporal Locality
Both Temporal & Spatial
none of the above
