Question

Difference between fixed length coding and variable length coding

Answer 1

This corresponds to a fixed-to-variable length code that encodes each word of fixed length by a codeword . A variable-to-fixed length code is a code that takes a string in , breaks it into pieces of variable length, and replaces each piece into a word of fixed length.

Answer 2

Fixed length and variable length coding:

• Fixed length means having a set length that never differs.  

• In database systems, a field can have a variable or a fixed length.

• A variable-length field is one whose length can be altered in each record, depending on what data is stored in the field.

• A code in which a fixed number of source symbols are determined into a fixed number of output symbols is called fixed length coding.
