If you have used a computer before, you know the frustration of having a computer that executes instructions slowly while on the other hand, you appreciate the convenience of a computer that executes instructions with speed. This is the reason why some people end up going to buy high-end computers even if they are very expensive. The secret behind the speed with which the computer you buy executes the instructions given to it has to do with the concept of cache (pronounced cash).

Defining Cache

The word cache is used to describe processes in two broad categories. The first refers to the process by which data can be stored locally in order that the speed of subsequent retrievals is enhanced. In this case, you are talking about web cache and browser cache. Then there are the areas in the computer memory that are dedicated and reserved for speeding up the execution of instruction, the retrieval, and updating of data. In these areas, you are talking about disk caches or memory caches.

In simple terms, think about the idea of cache as a temporary storage area. Take for example the files you request by going on to a web page. They are stored somewhere in a hard disk in a cache which is a subdirectory of the browser directory. When you want to go back to or review a page you looked at recently, the browser does not need to go to the original server to get the files, and it gets them from the cache. This serves you time and also reduces traffic going to the network.  

Memory Cache

The memory cache is sometimes known as the CPU Cache. This acts like a bank whose main purpose is to serve as a connection between the processor and the main memory. The static RAM (SRAM) chips in this memory are much faster than the dynamic RAM (DRAM) chips you find in the main memory. This is the cache that makes it possible for instructions to be executed and data written and read at higher speeds.

Disk Cache

The disk cache has a way of fastening things up. This cache is a section of the main memory that provides a connection between the disk itself and the computer processing unit (CPU). The reason why this makes things faster is that when a disk is read, more data will be read into the cache than the current requirements so that in subsequent reads if the data is needed, it does not have to be retrieved from the disk. This makes things faster.

Why Cache Matters

The cache on your computer matters because it has a bearing on how fast your processes are when you are using your PC. When you have a smaller cache, not much data can be processed at a given moment so you have to wait longer times to get the data you need. The bigger your cache, the less time you need load and scan through files. You always need to remember that you can increase the memory on your computer by using external USB devices and make things real fast. In the event that you decide to go in this directing, you can enhance your experience by using software such as DriverAssist. Apart from providing intelligence to the drivers, it can also help manage USB devices.
