    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.
