How is the hardware cache different from a software cache?
it means that you have to look it up because hardware cache is easy. software cache is hard and never easy. so look it up and you will find them both
Is Buffer cache is hardware entity?
I think No. Because buffer cache is a part of kernel and kernel is a software entity thats why buffer cache is also a software entity. However the buffer and the cache both are hardware entity separatly.
What is miss latency?
miss latency is the time (in cycles) the CPU waits when a miss happen in the cache. (the time needed to bring the data from the main memory to the cache).
Why is cache memory needed?
Cache Memory is needed because Hardware implements cache as a block of memory for temporary storage likely to be used again.
What is cache hit and cache miss?
Type your answer here... in cache memory when the CPU refer to the memory and find the word in cache it is said to be hit or produced....... if the word is not found in cache it is in main memory it counts as a miss
What is the objective of cache only memory architecture?
Cache memory is the high speed memories which are repeatedly requested by the Cache client (CPU). Whenever the requested data from the cpu is present in the cache, it directly supply the data and is known as cache hit(fast) and when the data is not accessible in cache then cache access the block of the main memory and feed to the CPU and it is termed as cache miss (slow).
What is cache miss penalty?
Additional time required because of a miss it is generally the 30~40 cycles for Main Memory.
What is the difference between cache vs cold cache vs hot cache vs warm cache vs cache hit vs cache miss?
Firstly, it sounds like you are asking for general definitions, rather than differential definitions, which is problematic when the definitions are differential and context specific. Cache miss: not in cache, must be loaded from the original source Cache hit: was loaded from cache (no implication of what "type" of cache was hit). cold cache: The slowest cache hit possible. The actual loading mechanism depends on the type of cache (CPU cache could refer to an L2 (or L3) hit, disk cache could refer to a RAM hit on the drive, web cache could refer to a drive cache hit) hot cache: The fastest cache hit possible. Depends on mechanism described (CPU could be L1 cache, disk could be OS cache hit, web cache could be RAM hit in cache device) Warm cache: Anything between, like L2 when L1 is hot and L3 is cold. It is a less precise term and often used to imply "hot" when the performance is closer to "cold."
Where you can buy a wooden handled junior hacksaw?
Any carpentry or hardware store
Where can you buy Flashdrives if you do not have a credit card?
Cannot be a problem if you have enough cache: go to the nearest hardware store.
Is cache memory a removable memory?
No, a cache memory is often used to store data that has been needed recently on grounds that it will be faster to access when/if it is needed again. When data that is requested is contained in the cache you have a cache hit, and when you have to retrieve it from the hard drive (or where ever its original storage was) again it is called a cache miss. Retrieving data from the hard drive is slower than retrieving it from the cache.
What will happen next if a cache miss occurs in the level 1 cache in a system with a level 1 and level 2 cache where will the required data be requested from next?
Cache misses move up the chain (or down the chain, if you want to think of it that way). If the information required is not in your L1 cache, then it checks for it in the L2 cache. If it isn't there either, then you need to go out and grab it from main memory.
