What is ROM?
Ans:
ROM: It is called Read Only Memory, is a Permanent or Semi-permanent Memory. The data is permanently stored and cannot be changed, in Permanent ROM. This can only be read from the memory. A write operation cannot be there since the specified data is programmed in the device through the manufacturer or the user. Also in Semi-permanent ROM write operation cannot be here, but the data can be changed, to a limited extent, by particular methods.
