                 Measuring the Computer’s Memory


                 The basic unit for measuring the memory of a computer is the byte. A byte consists of a
                 group of eight bits   or example  1   1 11  that is  1  yte e uals    its.   group o     its is
                 known as a nibble  hal  a  yte    or example  1  1  that is  1 ni  le e uals    its.

                 Other  units  for measuring the computer’s  memory  are  kilobyte, megabyte,  gigabyte,
                 terabyte, and so on.

                      RAM is a temporary memory.
                      Information stored in ROM is permanent in nature.
                      Secondary memory is permanent in nature and is not directly accessed by the CPU.
                      The basic unit for measuring the memory of a computer is byte.

                       Other units for measuring the computer’s memory are kilobyte, megabyte, gigabyte, terabyte,
                      and so on.
