Lenovo ThinkPad T420SI Ram
The RAM speed is dictated by the specs of the motherboard, while the actual storage size is guided by the OS. RAM is necessary in order for the Lenovo ThinkPad T420SI to run correctly. RAM is considered volatile memory as the data it holds is removed when the system shuts down. The RAM in your computer stores random bits of information for the CPU to use for programs. Because RAM is only temporary storage for the processor, it does not have the ability to store files such as picture or movies. But, it has a positive impact on the speed of your Lenovo ThinkPad T420SI. If there is ever a doubt, just know that it is impossible to have too much RAM!
