Qn #610
Which of the following is the smallest unit of data in a computer ?
Qn #424
In computer architecture, which of the following correctly matches the fundamental unit used in the CPU, cache, and main memory respectively?
Qn #418
Which of the following secondary storage devices has the fastest access time: Optical Drive, Magnetic Tape Drive, Hard Disk Drive (HDD), Solid State Drive (SDD)?
Qn #413
Dynamic RAM (DRAM) stores each bit of data in a separate capacitor. Due to leakage, the stored charge tends to dissipate over time and needs to be refreshed periodically. Consider the following statements:
P: DRAM requires refreshing because it uses capacitors to store bits. 
Q: SRAM does not require refreshing because it uses flip-flops instead of capacitors.
R: DRAM is faster than SRAM because it needs less frequent access.
S: DRAM is more suitable for main memory than SRAM due to its density.
