Message Encoding

Message encoding means turning a message or information into a specific format so it can be sent or understood by another person or device. When two computers are connected by a cable and need to communicate, message encoding is the process of turning the data into a format that can travel through the cable and be understood by both computers.

Steps of Message Encoding Between Two Computers:

1. Creating the Message: Suppose Computer A wants to send a message to Computer B (e.g., "Hello"). The message is initially in a human-readable form, like text.

2. Encoding the Message:

• Computer A doesn't send the text "Hello" directly through the cable. Instead, it encodes the message into a format that can travel over the network.
• This encoding translates the text into binary code (a series of 0s and 1s), since computers only understand binary. For example, "Hello" might be turned into a binary string like:
• H = 01001000
• e = 01100101
• l = 01101100
• l = 01101100
• o = 01101111

3. Sending the Message: The encoded binary message is then converted into electrical signals (in the case of a wired connection, like Ethernet). These electrical signals represent the binary 1s and 0s. The signals travel through the cable from Computer A to Computer B.

4. Receiving the Message: Computer B receives the electrical signals through the cable. It decodes the signals back into binary code (the series of 1s and 0s).

5. Decoding the Message: Computer B then takes this binary code and decodes it back into the original message (in this case, "Hello"), which is shown on the screen or used by a program.
