Study Notes

Rules of Communication

Effective communication requires an identified sender and receiver.
An agreed-upon method (e.g., face-to-face, phone, letter) is essential for clarity.
A common language and grammar must be used for understanding.
Proper speed and timing aid in effective message delivery.
Confirmation or acknowledgment of receipt may be necessary for some communications.

Message Encoding and Decoding

The encoder converts a message (text, images, audio) into a transmittable signal.
The decoder reverses this process to retrieve the original message.
Proper encoding and decoding are crucial for message transmission in networks.

Message Formatting and Encapsulation

Each message format must include identifiers for sender and recipient locations, greetings, and end indicators.
Following the personal letter analogy, components of the message are encapsulated, similar to packaging within an envelope.

Segmenting Messages for Packet Switched Networks

Messages cannot be arbitrarily large; they must be segmented to comply with frame size restrictions.
Each segment is encapsulated in its own frame with address information.
At the destination, frames are de-encapsulated, reassembled, and processed.

Timing in Communication

Message timing involves managing when devices can send and receive messages.
Access methods define sending timelines to prevent message collisions.
Flow control regulates the data transfer rate to avoid overflow.
Response timeout establishes limits on waiting times for replies to maintain timely communication.

Message Delivery Options

Unicast: Sends a message to a single specific recipient (one-to-one communication).
Multicast: Targets a specific group of recipients (one-to-many communication).
Broadcast: Distributes a message to all devices in the network (one-to-all communication).

Network Protocols and Standards

Network protocols consist of established rules governing how communications occur in a network.
Protocols ensure that different devices can communicate effectively and consistently across a network.
