Chapter II – Computer Organisation&"M:

• In ra$ we are using both rea! an! write o'erations because we can $o!i&y the errors easily

• It is a volatile

• I2 is a 2e$'orary "e$ory because &ro$ I/P to O/P we can 'er&or$ in 3"

• It is the "ain "e$ory or Pri$ary "e$ory because the 3" is closely relate! to +P1(Processor)

&OM:

• It is a Storage area

• In 3O" we are using only rea! o'eration because we nee! an in&or$ation at that ti$e we can retrieve

the !ata &ro$ 3O" to 3"



• It is a 6on-volatile

• It is a 'er$anent $e$ory because a&ter eecution all the 'rogra$s are store! 'er$anently

• I2 is secon!ary $e$ory because we are using &or storing the 'rogra$s only
