Intro to Cache Memory
Cache is not a term friendly to most people. In fact, it sounds more like a technical term to the general public. However, Cache Memory is essential in everyday component, and without it, the performance level of PC will decrease dramatically.
What is Cache
The CPU of a PC process Data and governs the general intelligence level of the computer. To open websites and run applications, the CPU needs to access the “Short-Term Memory” of a Computer, which is the RAM. What most people don’t know is, numerous Data can be stored in very tiny storage space and in such cases, sending Data to RAM would actually decrease the performance speed of a Computer.
This is where Cache Memory comes in. Cache Memories are basically smaller forms of Random Access Memory, used to store trace amounts of Data for optimum CPU performance. The Central Processors can access Cache Memory faster than the Random Access Memory and therefore, it is a better type of short-term storage than RAM in certain cases.
Types of Cache
There are two types of Cache used frequently at this point: L1 and L2 Cache.
L1 – Integrated into CPU, (usually) the smallest and the fastest form of Cache
L2 – Cache Memory between L1 and Random Access Memory. Slower than L1 but faster than RAM to access.
Premium Gaming Computers come with 6MB (Megabyte) or more incorporated Cache.
That is a simple explanation of the role of Cache in PC. I hope my short article helped.
