Access method RAM is random access ROM is not Volatility RAM

       Access method (RAM is random access, ROM is not)
       Volatility (RAM is volatile, ROM is not)
       Construction material (RAM is semiconductor, ROM is not)
       All of the above
       None of the above

Solution

RAM is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes.Most personal computers have a small amount of ROM (a few thousand bytes). Both types of memory (ROM and RAM) allow random access.

RAM is volatile, ROM is not.RAM is referred to as volatile memory and is lost when the power is turned off whereas ROM in non-volatile and the contents are retained even after the power is switched off.

Construction material:Both RAM and ROM are semiconductor
