Info about RAM
All about RAM
Term of memory RAM may have different meanings when it comes to computers with memory data retention mechanism that can be used by electronic equipment. A computer memory can be divided into two categories: internal memory or external memory or primary and secondary. Internal memory is the memory which can be accessed directly by the microprocessor and any amount of data to be processed before the CPU must first pass through the internal memory of the computer. External memory consists of different storage devices that hold information long term. Everything must go first to the internal memory size and operating speed of RAM directly influence the performance of a computer. This is one of the reasons that internal memory is brought into question every time when you must assess perfomance computer. Internal memory is composed almost entirely of RAM memory.
RAM means Random Access Memory that is random access memory. Random access means that no information contained in this type of memory are accessed at random, and random access feature refers to the possibility to make storing and accessing data in a non-sequential, which means that any quantity data can be accessed directly.
RAM is in the form of modules that can be purchased from local shops and mounted on the motherboard of the computer, either for its own or with help of specialists. RAM is where data arrive before being processed by the microprocessor and the memory of the computer desktop. Because everything passes through RAM, storage capacity and speed of RAM it directly affects PC performance.
Any software is designed to work in the presence of a certain minimum amount of RAM. If a computer is no minimum RAM required for a program that will refuse to start or will function improperly.
More RAM means better performance of your computer, or at least, like this they see things many good personal computer users. Do not try to resist the general opinions in some cases even doubling the amount of memory will not see practically no difference. RAM can provide data quickly because the microprocessor is an electronic component and do not have moving parts and most common storage devices.
If now a normal disk microprocessor can give approximately one hundred Mb / s of data per second, and RAM can provide data at speeds of over nine thousand MB / s for DDR3 technology. Random Access Memory chips fall in the current SDRAM technology type acronym coming from synchronous dynamic random-access memory and although all types of memory use SDRAM technology in everyday speech by SDRAM memory refers to memories old and for other types of memory uses only the name short. You must know that every generation of memory differs electrically and physically over the previous generation. In practice this means that we can not simultaneously use two types of RAM from different generations, and the key is a cavity in the memory module positioned differently from one generation to another which allows the introduction of a memory module just in the right position and only in a memory slot compatible.
