                      Identify the following and write their names:


                      1.                                                 2.

                 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, for example, 10001011, that is, 1 byte equals 8 bits. A group of 4 bits is
                 known as a nibble (half a byte), for example, 1001, that is, 1 nibble equals 4 bits.

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

                     1024 Megabytes          1 Gigabyte (GB)           1024 Kilobytes         1 Megabyte (MB)




                     1024 Gigabytes          1 Terabyte (TB)           1024 Terabytes          1 Petabyte (PB)



                     1024 Exabytes          1 Zettabyte (ZB)            1024 Petabytes          1 Exabyte (EB)




                    1024 Zettabytes          1 Yottabyte (YB)           1024 Yottabytes          1 Brontobyte



                                                1024 Brontobytes           1 Geopbyte


                       Let's REFRESH


                      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.
