The short answer is for speed. There is no point in storing data in a cache if there is no way to index the data to make it usable. Nor would there be any advantage if this data were stored in conventional DRAM.

which memory is used to hold the address of the data stored in a cache?
The memory used to hold the address of the data stored in a cache is typically referred to as the "tag" memory. Each cache line has an associated tag that identifies the specific block of main memory that the data corresponds to. When the processor checks the cache for data, it compares the requested address against the tags in the cache to determine if the data is present (cache hit) or not (cache miss).
What is the function of the tag field in a cache?
The tag field in a cache is used to identify which block of main memory is currently stored in a particular cache line. When the CPU requests data, the cache checks the tag field to determine if the requested data is present (a cache hit) or absent (a cache miss). Each cache line's tag holds the address of the corresponding memory block, allowing for efficient data retrieval while minimizing access times. This mechanism is crucial for maintaining data integrity and optimizing performance in memory access operations.
What is the purpose of the direct mapped cache tag in a computer system's memory management?
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.
How do you view cache file contents?
Cache files are stored in the same directory as Chrome. You also need to enable hidden files to view them.
What type of data is stored in cache memory?
Cache memory normally stored instructions and data that the processor likely to use frequently.
Where is information temporarily stored before it is sent to the CPU?
It is stored in the cache.
What is the difference between internal and external cache?
Internal cache is stored in a reserved area of the RAM of your computer. External cache is also called secondary cache or level 2 cache memory. It is external to the microprocessor and is stored on a separate chip.
What is stored in cache memory?
The data that are frequently used goes in the cache memory...
What does cache of food mean?
A stored food supply.
What do you call a place were weapons are stored?
a weapon cache
What is a Web Cache?
A Web cache is a temporary memory in your browser where temporary information about the web site you are visiting are stored. Information like login id, password, previous history of pages you visited etc would be stored in the cache...
Can you provide an example of how the tag index offset cache works?
The tag index offset cache is a memory structure used in computer systems to store frequently accessed data. An example of how it works is when a computer needs to access a specific piece of data, it first checks the cache using the tag (which identifies the data) and the index (which points to the location in the cache). If the data is found in the cache, it is retrieved quickly, saving time compared to accessing it from the main memory. This helps improve the overall performance of the system.
