Pronounced "Cash" this usually comes in two forms, either disk cache or memory cache, the former being a space normally on a hard disk set aside by the computer/software to store information it thinks it will need again, for instance browsers use disk cache to store information from websites such as pictures and alike, this reduces the need for the modem to keep downloading the same data each time you visit a webpage. The latter can either utilise normal memory or special memory which has a faster access time that is used by the system to store information that is used frequently, it can also 'guess' what information the user may require next and loads this into the cache memory for faster access.
