How does CPU cache memory increase the overall performance of your computer?
A) Increases the number of CPU cores
B) Moves twice as much data in a single cycle as a CPU without a cache
C) Increases the overall clock rate of the CPU
D) Provides faster access to information in memory
E) Uses fuel with a higher octane rating
The answer: D) Provides faster access to information in memory
A CPU cache is very fast memory that stores the data from frequently used memory locations. Because this information is in the fast cache, access to the data is much faster than requesting the data from slower memory locations.

Want to know more? Watch “CPU Technologies.” CPUs are extremely complex components, and their inner-workings can contain a mix of memory caches, multiple processor cores, and advanced queuing mechanisms. In this video, you’ll learn how these technologies work together to create today’s modern central processing units. |
