What are the components of main memory?

Computer memory is of two basic types – Primary memory(RAM and ROM) and Secondary memory (hard drive, CD, etc). Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory.

What is the purpose of the main memory component?

RAM is measured by its speed ( MHz ) and by its size (megabytes or gigabytes). For example you could have DDR RAM (name) 400mhz (speed of the RAM) 256mb (RAM size). The most common RAM sizes are, 16mb, 32mb,64mb, 128mb, 512mb, 1Gb and 2Gb.

What are the characteristics of computer main memory?

What is Primary Memory’s Characteristics: The primary memory of computer is also called main memory, temporary memory, or prime memory. It is a volatile memory. This memory is made of semiconductors technology. Data is automatically deleted in the event of power failure. Thie processing speed is faster than secondary memory. This is the main working memory of the computer.
