Which of the following types of memory cannot be changed after its written?

A.
RAM (Random Access Memory)

B.
Cache

C.
WORM (Write Once Read Many)

D.
EPROM (Erasable and Programmable Read Only Memory)

Explanation:
Write Once Read Many (WORM) can only be written to once. Random Access
Memory (RAM) and Erasable and Programmable Read Only Memory (EPROM) can both be
erased and rewritten. Cache can also be rewritten, and is used to optimize data
access performance by creating a temporary memory space used to access data already
requested or related data that has the likelihood of being needed soon. Access to
data in cache will be much faster than if the computer had to hunt up and write the
data to memory from the hard disk.
