Understanding Latency and Throughput
Latency refers to the delay between a remist and te response, typically measured id nanosomns or clock cycles. Throughput indicates the concentt of data processed in a given time, often expressed in bytes pes second. Both metrics are riciadel inrecating memory y system performe.

Összhangban a memory system with a latency of 50 nanosomns and a data transfer rate of 1 gigabyte pez second. To evaluate performance, calculate the number of data units transferred persond:
- Data transferred- per second: 1 GB = 1,000,000,000 bytes

- Data pel latency: (1,000,000,000 bájt) x (50 x 10)
A tiss calculation azt mutatja, hogy a jelen esetben a caplately 50 bytes cen be transferred during the latency period, illusztrating the relationship between latency and throutput in system design.
