Difference between DDR and flash drives

There are various forms of computer memory available in the market area of ​​equipment and every memory has its own specific role to play. Flash memory and DDR MEM two large computer memory that come with desktops and laptops. If you already buy member upgrade information technology, it is very important that you know the difference between flash memory and the members of the GDR.

Flash memory is a special type of memory that can be programmed and can be erased and reprogrammed electronically. A member of the non-volatile flash memory is the best computer and user-friendly nature of memory, the effective use of game consoles and memory cards makes. Flash memory in USB flash drives are used to easily fix the USB ports and users can easily store data on them. The area where it's extensive use of flash memory includes portable computers, PDAs, digital cameras, music players and telephones. FLASH MEM is non-volatile memories are not lost all data when they are not removed or stored in the RAM mem. FLASH MEM comes in two forms, namely NAND and NOR. NI can easily make fully accessible to all members with the location data and address bus. However, NAND has written more quickly and the deletion of the time, but not random access. NAND Flash is used for members of memory cards, but is not intended to be used as a replacement for ROM chips. However, there are limits to the flash memory and most important is that the flash can be erased and rewritten, only a finite number of times. But although flash memory can be erased and rewritten for a finite number of times, is regarded as the most popular memory, that the difference may be on your computer and add the laptop and run efficiently.

Then the members of the GDR. This type of membership is quite common in desktop computers. MEM DDR Double Data Rate SDRAM as well known is twice as fast as SDRAM developed. MEM DDR can be easily to2133MB data / s, and the best part is that less energy than standard SD RAM memory consumed. There are several variants in the market for DDR RAM. DDR1, DDR2 and DDR3 are the most common species, and make sure that you will be MEM DDR compatible with your computer system.

If Dell or HP or Sony or any other brand, the only thing, if you buy memory upgrade is compatible affairs. Dell Memory upgrade option is to make a right, if your computer's memory to be increased. For exactly the kind of memory that is with your Dell desktop or laptop, you should opt for the selection of the memory. The role of the Memory Selector is to find adequate support for DDR1, DDR2 or DDR3 memory with improvements in desktop or laptop.
