Computer Systems are generally comprised of several component parts that include a Microprocessor, Hard Disk, Computer Memory, Data Buses and other Peripheral Devices and components. Computer Memories are semiconductor storage devices for holding programs or data. Although computer memory can refer to many types of memory within the computer, typically it refers to Random Access Memory (RAM). RAMs are used for the short term storage of program instructions and data during the execution of a program. If the CPU had to constantly access the hard drive to retrieve data, it would operate very slowly. Every time a program is loaded or opened, it’s placed into RAM. The CPU requests the data it needs from RAM, processes it and writes new data back into RAM. The amount of memory that a computer system must possess depends on the type of computer, the types of programs that are run on it and the number of programs opened at a given time. ...
