What is Buffer Memory? Like on a complex drive it say: 16MB buffer memory. what is it exactly and whats it for.?

Buffer memory are solid state memories (Static RAM for Hard disk) that will relieve store data/commands temporaily to help speed up the access time of the drive.



Since tricky disks are mechanical devices, their access speed will not contest up to access time of solid state memory since they have to position their R/W pave the way to the correct tracks and sectors first back R/W can take place.



Typical access time for sturdy disk is like 8ms, static RAM access time is resembling 10ns.
Buffer memory is used to hold data while the rugged drive processes other information at the same time.

The processor is a fastest one compare beside your hard drive. The processor should linger for some time till the hard drive help yourself to the reqired files. Think like this, the processor tender request to take a wallet. The harddirve will take the wallet and store it in a temprory space. Till this process undergone the processor can do some other process is it? for this purpose the buffer memory used. The buffer memory is zilch but static ram. Not with the sole purpose in the strong dirve the buffer memory used in various places such as printers.
A certain portion of concrete disc memory is utilised as buffer to store the temprory files during processing. This over and above the RAm memorry. I can give you a relation that deals next to hard drive problems. Some drive problems can be efficiently fixed by yourself using easily available tools.
