: The main memory of computer is RAM and ROM. ROM Mother Bird has built-in. There are many pots in Motherbird for planting radam. The unit of measurement of RAM is gigabyte ( GB) . The more RAM you use, the faster the work. At least 1 GB of RAM is enough for normal work. More RAM needed for graphics to work. Radam is available in different modules in the market. For example: 1GB, 2GB etc. Radam can be from different companies. In the case of Radam, the company is not so much a consideration. The main issue is what kind of RAM is used. The current two types of RAM are more common. EDO (Extended Data Out) and SD (Synchronous Dynamic) RAM . SD is faster than EDO . Because SD has a bust counter inside that speeds up memory access. Double Data Rate Synchronous Dynamic Access Memory or DDR SDRAM ( Double Data Rate Synchronous Dynamic RAM - DDR SDRAM) is the same as SDRAM . However, it has higher bandwidth which means greater speed.
