Question

Computers invariably use RAM for __________

(a) High complexity

(b) High resolution

(c) High speed main memory

(d) High flexibility

I got this question during an interview for a job.

Query is from Random Access Memory topic in section Memory Devices of Digital Circuits

Answer 1

Right option is (c) High speed main memory

To explain: RAM is a volatile memory, therefore it stores data as long as power is on. RAM is also known as RWM (i.e. Read Write Memory). Computers invariably use RAM for their high high-speed main memory and then use backup or slower-speed memories to hold auxiliary data.
