1.	CD-ROM is a __________(a) Memory register(b) Magnetic memory(c) Semiconductor memory(d) Non-volatile memoryThe question was posed to me during an interview.Query is from Random Access Memory in chapter Memory Devices of Digital Circuits
Answer» Right answer is (d) Non-volatile MEMORY Easiest explanation: CD-ROM is a non-volatile memory. Once a program is UPLOADED in it then it can’t be ERASABLE. Thus, it stores the data permanently.
