Memory units:The amount of data that can be stored in a storage unit is known as a memory unit. A binary digit or 'bit' is the representation of '0' and '1' is considered the smallest unit of memory. A group of binary digits (8-bit) is called bytes. The table below is showing the memory units and their equivalents:Unit MeasurementEquivalent1 bit0 or 10 or 11 nibble4 bit4 bit1 byte8 bit8 bit1 KB (kilobyte)1024 byte103 byte1 MB (megabyte)1024 kb106 byte1 GB (gigabyte)1024 MB109 byte1 TB (terabyte)1024 GB1012 byte1 PB (petabyte)1024 TB1015 byte1 EB (exabyte)1024 PB1018 byte1 ZB (zettabyte)1024 EB1021 byte1 YB (yottabyte)1024 ZB1024 byte1 BB (Brontobyte)1024 YB1027 byte1 Geopbyte1024 BB1030 byte Confusion Points2 TB is equivalent to 2048 GB1GB is equivalent to 1024 MBSo, 1500 MB is greater than 1 GB or 1024 MBTherefore, the correct sequence is 2 TBytes > 1500 M Bytes > 1 G Bytes > 5 K Bytes Hence, the correct sequence is (D), (A), (C), (B).
