The difference between RAM, DDR and DIMM

-There are many different types of computer memory. For someone who has not spent years studying, it may seem like a lot of information that goes directly on the head. To be sure, the computer memory is complicated, but the knowledge is not as inaccessible as most people think.

RAM

RAM stands for Random Access Memory. It was invented in 1949, but he looked very different back then. Even in 1949, when the computer screen was an ideal of science fiction, the RAM has played a role in the functioning of a computer. RAM allows data to be stored in any order, and the computer to be accessed in any order. Before RAM was popularized, computers had to follow a chain of unrelated data whenever they wanted access to anything. RAM is used in modern computers as a short-term memory and data storage. This is a flash memory, so that it can be rewritten many times as necessary. Because it is a volatile form of data storage, it requires a constant power supply. But this means that a constant power access time much faster than the non-volatile memory such as hard disks, and it stores the programs and files that are in use.

DDR

Another type of RAM is DDR RAM. DDR stands for Double Data Rate. DDR RAM is twice faster than the older versions of RAM. What most people think of you today is that RAM DDR RAM, which was first published in June 2000. And in 2003 it was even better with DDR2 RAM, faster than even that is DDR RAM.

DIMM

All DIMMs are RAM (or more precisely DDR2 RAM these days), but not all RAM is DIMM. Means DIMM Dual Inline Memory Module. A DIMM is essential that a stick of RAM. This circuit is long, thin and narrow with tabs on one edge. These tabs are studded with flat metal pins. The pins are responsible for the transfer of data between the DIMM and the computer. If you watch a DIMM stick, two main things will stick out, the metal green and black squares that out. The black squares are the RAM. The green part, the part that makes DIMM, connecting the squares of a timely and effective manner.

the difference

In terms of what is available today, the only difference that matters is that the compatibility of the computer are specific. And IBM computer must have a DIMM or equivalent 5913-8202. HP must have a DIMM HP, so on and so forth. Other than speed capabilities and computer compatibility, there really is no différence entre RAM, DDR RAM and DIMM. Because essentially they integrate all aspects of each other anyway.
