Sony VGN-UX390N Ram

Random Access Memory, RAM, stores small bits of information that the central processing unit uses for programs. The speed of the RAM is imposed within the specifications from the motherboard, while the actual storage size is guided by the operating system. Random Access Memory is considered volatile memory as its storage is removed every time your turn the computer off. Your laptop will do nothing at all without having the RAM installed. Because RAM is only temporary storage for the CPU, it does not have the ability to store files such as documents or pictures. Instead, it will affect the speed of the computer. If you are ever in doubt, just know that it is impossible to have too much RAM!
