Difference Between Encoding and Decoding

Encoding and decoding are two very important concepts in communication systems and data transmission. Encoding is the process of transforming information from one form to another so that it can be sent or stored more efficiently. Decoding is the reverse process, converting the encoded information back into its original form. While encoding and decoding are two distinct processes, they are closely related and are often performed together in the same communication system.

What is Encoding?

Encoding is the process of transforming data from its original form into a different form. It is a process of converting information from one representation to another. This process makes it easier to transmit and store the data. For example, when you type a text message on your phone, the message is encoded into a digital format which can be sent as an SMS. Encoding is also used to compress data, making it more efficient to transmit and store.

Types of Encoding

There are many different types of encoding, such as ASCII, Unicode, Base64, and Base128. Each type of encoding has its own advantages and disadvantages. ASCII is a common encoding used for text files, while Unicode is used for international characters. Base64 is an efficient way of compressing data, while Base128 is used for compressing large amounts of data.
