Lenovo ThinkCentre 8155 Ram

RAM is considered volatile memory as the data it holds is removed when you shut down your system. Your desktop cannot run without having the RAM installed. The RAM in your computer stores random bits of information that the central processing unit uses for programs. The speed of the RAM is prescribed within the specs of the motherboard, while the actual storage size is determined by the OS. Due to the fact that RAM is temporary storage for the CPU, it does not have the ability to store files such as picture or movies. Instead, it will affect the overall speed and quickness of your Lenovo. If you are unsure about the size of the RAM to buy, just know that it is impossible to have too much RAM!
