Fujitsu LIFEBOOK S4545 Ram

Having the RAM installed is mandatory for your laptop to boot up. The RAM speed is governed by the specs of the motherboard, while the size is dictated by the OS. RAM is considered volatile memory as all the information held gets deleted when you shut down your system. Random Access Memory, RAM, stores random bits of information that the central processing unit uses for executing commands. Because RAM is only temporary storage for the CPU, it does not have the ability to store files such as picture or movies. Instead, it will affect the speed of your laptop. If you are ever in doubt, remember that you can never have too much RAM.
