What Is Cache Memory?

The memory is the main working area of the computer. A computer does all the work in the memory. Data is transferred from memory to processor for processing. The operating system manages this process.

The cache memory is also a random access memory but it works faster than the traditional RAM. The data which is going to be processed by the processor is already presented in the cache memory. The operating system uses the cache memory to reduce the time for searching of data. The required data is always provided in the cache for processing. The cache is very effective. The reason is most programs share same data and instruction again and again.

In some processors the cache memory is built in. Some processors don't have the cache memory. The main difference between Intel Celeron and Intel original technology was of cache memory. The cache memory is also costly then the traditional RAM.

The web browsers also used cache memory to store the visited pages of different websites. These stored pages are used to for quick access when we want them again or want to get them offline. The browsers store images, sounds, URLs and other objects.
