If a cache can be made as large as the device for which it is caching for instance a cache as large as a disk why not make it that large and eliminate the device?
Though the size of a cache has increased over time, so too has the size of hard disk. An economical comparison of cache versus hard disk space in a cost per MB analsysis will show that a cache would be significantly more expensive. Furthermore, cache in general is considered "temporary" or volatile storage which means that the contents of the storage device is lost when the system is powered off. A hard disk, on the other hand, is "long term" or non-volatile storage; when the system is powered off, the hard disk still safely holds the data stored on it.
What is memory allocation?
Memory allocation is the act of reserving a chunk of memory for some set of data. In programming terms, this is normally done by declaring a variable. Large arrays of data will require large blocks of contiguous memory, which the programmer must request from the operating system.
