Which of the following is a type of memory that is directly connected to the CPU without a bus?
A. RAM
B. Registers
C. Hard disk
D. Cache
Answer: Option B
Solution (By JKSSB Mock Tests)
Registers are internal to the CPU and are directly connected to the execution units, providing the fastest access. Cache is on-chip but may have a bus; RAM and HDD are external.
