Study Notes

Computer communication is the process of transferring data, instructions, and information between computers or devices.

Earlier, only large computers had communication capabilities.
Today, even smaller computers and devices can communicate directly with each other.

SENDER: The device that initiates sending data, instructions, or information (e.g., computer or mobile device).
COMMUNICATION CHANNEL OR TRANSMISSION MEDIA: The medium through which data travels (e.g., cables, microwave stations, or satellites).
RECEIVER: The device that accepts the transmission of data, instructions, or information (e.g., computer or mobile device).
PROTOCOL: A set of rules that outlines how devices communicate, including data format, coding schemes, and sequence of data transfer.

Without protocol, devices cannot transfer or exchange data.
Protocol is necessary for successful communication between devices.
Example: A person who knows only English cannot communicate with someone who knows only Hindi, illustrating the need for a common language (protocol) for communication.
