Memory is one of the most important thing, which is built into computers, notebooks whether or PC. Some types of computer memory that is installed according to the actual functionality and specifications required by the system. A computer connected to the memory of most devices and components that are responsible for storing data and applications for temporary or permanent basis. This allows the person to keep information stored on your computer. Otherwise, the processor can not find a place to store the necessary calculations and processes. Different types of computer memory that has many functions for data storage. Each specific features and capabilities.
The main types of computer memory Explanation
Random Access Memory (RAM)
RAM space for a computer system that is responsible for each other's data on a temporary basis, it is immediately accessible to the processor. The data stored in memory, as a rule, completed a computer hard disk, and includes data pertaining to the operating system and some applications. When the system is turned off, RAM loses its stored information. The data is still stored and must be preserved if the system works.
If the memory is full, the computer system is slower than it should. Data can be obtained in any particular order. In general, two types of memory, namely, static RAM (SRAM) and dynamic RAM (DRAM). If your computer is running many programs at the same time, virtual memory allows the computer to look for RAM memory elements that are not used recently and copy it to your hard drive. This process frees the memory space and allows the system to load different programs.
Read Only Memory (ROM)
This type of memory is active, regardless of whether the system is turned on or off. This is a kind of permanent memory storage. As the name implies "read only" offers, the contents can not be changed or modified. This integrated circuit, pre-programmed data must play an important role in the computer performs the usual functions.
Cache
Cache is a kind of memory your computer for access to more responsible than conventional RAM. The central processing unit is in the cache memory, main memory before searching a container to determine the required information. This eliminates the need for a retrieval system, more and more memory, storage space, which leads to faster retrieval of data.
Hard drive
These tools are important components for data storage that are installed on the processor. Wide range of memory and the user can select the memory function of the data required for the storage and access. Currently, hard drives, which are memory capacity of 120 GB and 500 GB are generally used.
Flash memory
This type of non-volatile memory, which is intended to contribute to the portable storage and convenient data from one computer to another. Data can be erased and reprogrammed in accordance with user needs. This is only a certain number of write cycles to remove and to be able to resist, and then creates a tendency to loss of stored information. Memory cards and USB flash drives are a few ways this type of memory storage.
This is only general types of memory and a central computer, which contribute to memory and storage. There are many subtypes, which can be sorted depending on the memory-related functions they perform, as well as requirements that they serve.
