What do you mean by CACHE?
If there is an augmentation of a remote file access protocol, each client maintains a cache which caches translations from the file names that corresponds the file of the handlers.
What should be the issue which will be considered in implementing the name cache?
Please explain it in detail for more appropriate information.
Thank you.
The cache is a small amount of high-speed memory, usually with a memory cycle time compared to the time required by the CPU to fetch one instruction. The cache is usually filled from main memory when instructions or data are fetched into the CPU.
Often the main memory will supply a wider data word to the cache than the CPU requires, filling the cache more rapidly. This type of memory is very expensive, because each memory location must have both a comparator and a storage element. Data words are loaded into the cache at one time, providing a kind of perfecting for instructions or data.
CACHE(pronounced cash)is defined as 'the block of RAM whose function is to store data temporarily is likely to be used again. When you request a file by looking at a Web page that are stored on your hard disk in a CACHE subdirectory under the directory for your browser (for example:Internet Explorer).
When you return back to a page you have recently visited at, the browser can get it from the CACHE rather than the original server.
Cache (Pronounced as CASH not CASHEY) is a temporary place to keep a copy of information for faster retrieval on the second request for said information. The original data may take time to be brought because of the difference in access time between components. Thus, a cache can act as a temporary storage where data which are most frequently accessed are stored so fast processing. In future processing, the CPU may just access the duplicated copy instead of getting it from the physical disk storage which is slower and performance can suffer. Therefore, Caching increases the speed at which your computer pulls bits and bytes from memory.
I don't' think that there would be any issues in implementing name cache.
Dear Chikki,
Cache memory is very fast speed memory. Cache memory is available on two locations in a computer.
On motherboard as L1 cache.
In microprocessor or CPU as L2 cache.
Cache memory I placed on very nearest location to processor. So that it has a very high speed than RAM.
Cache memory is used to store recent commands.
When we open a file by double clicking, the file will take some seconds to open. But when we close the file and open it again then it opens rashly.
Why? Because now the open command of that file is stored in Cache memory and processor picks this command from there. He will not check the Hard Disk and RAM to get command.
We cannot store files manually in cache memory. It stores just commands only.
I hope you got your answer.
Thanks
