  1. Which of the following is in the ascending order of Data hierarchy?
    1. Byte–Bit–File–Record–Database–Field
    2. Field–Byte–Bit–Record–File– Database
    3. Bit–Byte–Record–Field–Database–File
    4. Bit–Byte–Field–Record–File– Database
Correct Option: D

Data is organized in a data storage hierarchy of increasingly complex levels: bits, bytes (characters), fields, records, files, and databases. Data are logically organized into: l Bits (characters): - a bit is the smallest unit of data representation (0 or 1); l Byte: a unit of digital information that most commonly consists of 8 bits; l Field: a field consists of a grouping of characters; l Record: record consists of fields, with each field describing an attribute of the entity; l File: a group of related records; l Database: an integrated collection of logically related records or files.
