Study Notes
Computer Communication
- Computer communication is the process of transferring data, instructions, and information between computers or devices.
Evolution of Computer Communication
- Earlier, only large computers had communication capabilities.
- Today, even smaller computers and devices can communicate directly with each other.
Methods of Computer Communication
- Communication can be done through cables and wires.
- Communication can be done wirelessly through the air.
Components of Computer Communication
- 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.
Importance of Protocol
- 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.
