Have you ever wondered what latency means and why it the most crucial word of our times.
Latency in simple terms mean wasted time.
The less the latency, the better the communication between the two nodes in any unit.
Latency greatly affects how usable and enjoyable electronic and mechanical devices as well as communications are.
As you would expect,latencyis important, very important.
As programmers, you must be knowing the fact that reading from disk takes longer than reading from memory.
Another interesting fact about computers is that L1 cache is faster than the L2 cache.
But do you know the orders of magnitude by which these aspects are faster/slower compared to others?
The table below presents the latency for the most common hardware operations.
These data are only approximations and will vary with the hardware and the execution environment of your code.
