Question

What is the difference between fixed length and variable length according schemes.

Answer 1

Explanation:

In a fixed-length code each codeword has the same length. In a variable-length code codewords may have different lengths. Here are examples of fixed and vari- able legth codes for our problem.

Answer 2

A fixed length variable is one whose length never varies, whereas a variable one is whose length varies with changes in inputs.

• The fixed length ensures the fixed length is never variable.
• A variable-length is one in which the length of each record can vary, depending on what data is stored in the field.
• While the fixed length,  leads to wastage of memory, the variable length is a memory efficient variable.
