Question

You are reviewing new RAM to purchase for a gaming computer and find three different RAM modules that are the same except for their CAS Latency. Option A lists the CL as 18 ns, Option B lists the CL as 20 ns, and Option C lists the CL as 15 ns.

Answer 1

Answer:

The review will state that the Option C RAM ( with CAS Latency 15 ) will the most efficient one among the three, Option A list will be moderately efficient and Option B will have least efficient RAM.

Explanation:

CAS Latency is actually Clock Address Strobes that defines the number of clock cycles the RAM takes to make the specified data available to its pins from where the data is than read by the processor for its usage. So, the greater the CAS Latency ( often specified as xyz ns ) the less efficient the RAM is. That's why in the review it will be Option C list Ram with least CAS Latency to be choose as maximum efficient.
