Understanding and Caching Functions on a Computer

Gadgetsiana.com - Understanding Cache on the computer. The cache or can also be called by caching may sound unfamiliar to most people, but for people who study computer science, it will most often hear this term.

Cache is a small-sized memory that is temporary in nature. Although the file size is very small, but the speed is very high. In hardware terminology, this term usually refers to a high-speed memory that bridges the flow of data between processors and the main memory (RAM) that usually has a much lower speed.

Understanding Cache on the computer

Cache usage is intended to minimize the occurrence of bottlenecks in data streams between processor and RAM. While in software terminology, the term refers to temporary storage for some frequently accessed files (usually applied in network). Caches are generally divided into several types, such as L1 cache, L2 cache and L3 cache

Cache is a data storage mechanism that has a very high speed that is used to store data or commands/instructions that are often diicari by computer users or smartphone users. Usually the cache will often be encountered in the browser used to access the Internet. We will see such a command or instruction that we have put into the computer so that when we interpret something it will appear options or choices of words or sentences that we have used before. 

Or Cache can also save some files that we have previously accessed so that when we or others in one network that will access the same file or data then the Cache will display the file.

In addition, caching can also be interpreted as a temporary stored data on the internal storage of your computer device or smartphone device. The cache itself will save the activity performed by the user against the use of a computer or smartphone so that when we will re-access the data that has been accessed, the cache will quickly display the data. 

The cache has a small size so that the cache will help accelerate the computer's performance process to open applications or website pages faster. For a network administrator, the settings or configuration of the cache on the router or server device will be very useful because it will save usage bandwidth will also accelerate data access.

Cache function on computer


Basically Cache function is to help speed up your computer device or smartphones to access the data so it will ease the processor performance. In addition to the other functions of the cache are as follows:
  1. With Cache allows users to speed up data access on a computer.
  2. The Cache can also be used to bridge the speed difference between the main memory and the CPU.
  3. Caching will make memory performance faster.
  4. Caching can also improve processor performance because the role of the cache will greatly help the process of data access on the computer.

Cache types


There are several types of cache that are commonly used, including:

Memory Cache


Memory caches are often also called RAM caches. This is a portion of memory created with high speed static RAM (SRAM). This type of cache is more effective as almost all programs can access the same data or commands over and over again. That means that the more information is stored in SRAM, the more often the computer uses this cache rather than using the relatively slower DRAM. 

The memory Cache has three levels. You've certainly seen the L1 Cache, L2 cache or L3 Cache label in your computer's device box or in its specification information pack. L1 is a designation for internal caching, it inhabit parts between the CPU and DRAM. This Cache has the highest access speed. The memory size is growing from 8Kb, 64Kb and 128Kb. 

While L2 is an external cache that has a larger capacity ranging from 256Kb to 2Mb. But the speed, L2 is even slower than L1. Lastly, the L3 Cache is usually found in newer models of computers that have more than one processor unit, such as dual cores or quad cores. L3 serves as a data manager accessed from the L2 cache and each processor core.

Disk Cache


Not much different from Memory Cache, Disk Cache is also on the same principle. But instead of SRAM's high-speed data, the disk cache uses conventional memory, or is called a relatively slower dynamic RAM (DRAM). How it works, when you run an application that requires data from a disk, the application will first check the availability of its data in the memory buffer. Disk Cache is capable of having a significant speed impact on application performance, as this mechanism is much faster than retrieving data from hard drive components. 

These are some of the things you can learn about caching on your computer. Cache has important functions in a computer, as well as web hosting on a website. Now, you can register your website using trusted and cheapest web hosting in Indonesia that is Idwebhost. There are a lot of advantages that Idwebhost has to help develop your business website such as 24-hour support, reliable servers, up to 99.99% uptime and much more. 

That's what the cache and Cache function on computer can be useful and see you at the rest of the discussion.
