Advantages And Disadvantages Of Primary Memory

Decent Essays

Random-Access Memory (RAM), Cache, Hard Disk, Read-Only Memory (ROM)

(i) The main disadvantages of primary memory are that it has a relatively smaller storage capacity and is volatile which means data stored in the primary memory is temporary and is lost when the computer or laptop is shut down and is no longer powered. Primary memory devices are also relatively more costly to purchase and install in the computer.

(ii) The main disadvantages of secondary memory are that it is located further away from the Central Processing Unit (CPU) and therefore, the speed at which data stored in secondary memory can be accessed is slower.

Combining the two types of memory into one single memory device is not likely to be feasible as the two memory devices (primary and secondary) are designed to form a memory hierarchy in the …show more content…

Thus, the hierarchical system of accessing data in the primary and secondary memory devices at different speeds will not work. This may result in an overall reduction in the speed at which data in the memory device is accessed by the
CPU, thus decreasing the performance of the CPU.

A single memory device may also result in overheating and a higher energy consumption. Also, a single memory device that incorporates the features of both the primary and secondary memory devices may be costly to manufacture and thus, may not be affordable for all users.
