What Type Of Memory Is Inside My Computer? How Do They Work?

A CPU consists of mainly two kinds of memory units known as Primary memory and Secondary memory. The Primary memory unit includes Random Access Memory and Read Only Memory units. Secondary Memory includes the outsourced memory devices like compact discs, digital video discs, pen-drives, etc.

Every computer consists of these memories, and no computer can work without primary memory unit. RAM contains cache memory which is temporary and volatile. ROM is non-volatile and reserves information. For example, while working on MS Word, the temporary working is stored in RAM unit, but once the document loads, it settles in the ROM unit. Therefore every computer importantly maintains Primary Memory Unit and Secondary Memory Unit is optional.
