Question

Compare and contrast Web caching design and cache design in computer memory hierarchy. Select all correct answers.

a. Both designs deal with software design only.
b. Both designs use temporary locality.
c. Web caching data are always stored in the secondary memory (disk).
d. Computer memory hierarchy supports Web caching and automatically place Web caching data in cache, in main memory, or in the secondary memory (disk).

Answer 1

Web caching design and cache design in computer memory hierarchy are two different approaches, with differences in the type of data and storage locations. They both employ temporary locality to optimize data retrieval.

Step-by-step explanation:

Comparison of Web Caching Design and Cache Design in Computer Memory Hierarchy

In web caching design, data from the internet is temporarily stored in a cache to reduce the time it takes to retrieve information. This data can be stored in either the cache or the secondary memory (disk). On the other hand, cache design in computer memory hierarchy involves storing frequently used data in a cache located closer to the processor, such as the main memory or cache memory.

Differences:

1. Web caching design deals with data from the internet, while cache design in memory hierarchy deals with data within the computer system.
2. Web caching data can be stored in the secondary memory (disk), while cache design focuses on storing data in the cache or main memory.

Similarities:

• Both designs utilize the concept of temporary locality, where frequently accessed data is stored in a cache for faster retrieval.
