|"Types of RAM
If you have started looking at upgrading your RAM you will almost certainly have discovered that there are many different types of RAM. RAM can differ in the actual hardware specifications, that is how the RAM chip actually works, but also the same type of RAM chip can have many different varieties, differentiated by their storage capacities - for example 128MB or 512MB.
Some of the more common types of RAM are: "
|Types of RAM
Dynamic RAM (DRAM) is perhaps one of the most common types of RAM available. DRAM is used to store information that is being passed around a computer and between peripherals. The information is not actually saved, it is temporarily stored in memory until the curent process has finished.
DRAM needs a way to remember the information it is storing, and the process by which it achieves this is a large contributor to it being known as dynamic RAM. DRAM must be constantly refreshed, not just every now and then, but repeatedly each second. If this process did not take place DRAM would not be able to hang on to the information it is storing.
The reason DRAM needs to be refreshed in this way is because in effect it stores information via electrical charges. These electrical charges weaken, similarly to a normal battery, if the electrical charge becomes too weak then the information will be lost from memory.
|Types of RAM
EDO DRAM is an abbreviation for Extended Data Out Dynamic Random Access Memory, EDO RAM is therefore a type of DRAM. So what on earth does that mean?? Well the name gives us a little clue, albeit kind of cryptic - the Extended Data Out name relates to the fact that EDO RAM does not have to finish processing the first bit before continuing to the next one. Remember that a bit is actually a Binary Digit and this is how information is stored in memory.
EDO RAM is faster than its standard counterpart DRAM. The improvement comes from the fact that as soon as the location of the first cell is discovered, EDO RAM will begin looking for the next address. EDO represented an improvement in performance, however, it now has a superior successor in the form of SDRAM.
|Types of RAM
SDRAM is an abbreviation for Synchronous Dynamic Random Access Memory. SDRAM can be considered a replacement for the earlier EDO DRAM. SDRAM is actually synchronised with the computers system clock> It is able to increase performance by taking advantage of interleaving, which is the process whereby the SDRAM module is able to access a cell at the same time as finishing one.
SDRAM also works on the assumption that most of the time the data required by the CPU will actually be in sequence - rather than a totally random distribution. Therefore SDRAM will stay on its current row (bits are addressed through rows and columns) and move across each column reading each bit along the way.

Productivity software can be any application that helps the user accomplish a specific task, whether the task involves generating text or graphics, working with numbers, searching for data, or preparing a presentation.
