is a form of used in computers. Taken in the form of integrated circuits which represents primary or temporary storage, it allows data which is stored to be accessed in any order, which is why it’s called random.

How do you explain memory?

Memory is

the sum total of what we remember

and gives us the capability to learn and adapt from previous experiences as well as to build relationships. It is the ability to remember past experiences, and the power or process of recalling to mind previously learned facts, experiences, impressions, skills and habits.

Is ROM main memory?

is of two basic type – 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

. It is also called as read write memory or the main memory or the primary memory.

RAM is faster than

ROM just because writing data to a ROM chip is a slow process
