Memory is one of the most critical system components in any computer. It is RAM that has allowed computers in the past and present to operate at such snappy speeds. You can picture RAM as one big buffer used to store any data temporarily for ultra fast access from the CPU (Central Processing Unit) or other components, allowing such component to go about its business with minimal delay.
