Which of the following is a typical latency value for DDR4 RAM?
A. CL18-CL22
B. CL14-CL16
C. CL9-CL11
D. CL30-CL36
Answer: Option B
Solution (By JKSSB Mock Tests)
DDR4 common CAS latencies are around 14-16, though higher speeds may have CL18-22. DDR3 had CL9-11. DDR5 is higher (CL30+). So A is correct for typical DDR4.
Explanation:
Magnetic tape systems lack addressable coordinate sectors, forcing the drive mechanism to advance or rewind linearly through the tape roll to reach a specific block.
