Study Notes
Communication Methods
- All communication involves three main elements: Source (sender), Destination (receiver), and Channel (media).
- Protocols are essential for efficient communication, ensuring clarity and understanding between parties.
Importance of Protocols
- Effective communication requires defined protocols, which include:
- Identified sender and receiver
- Common language and grammar
- Speed and timing of message delivery
- Requirements for confirmation or acknowledgment
Network Communication Protocols
- Honeycomb of network protocols includes:
- Message Encoding: Transforming information into acceptable formats for transmission.
-
Message Delivery Options:
- Unicast: One-to-one communication.
- Multicast: One-to-many communication.
- Broadcast: One-to-all communication.
- Message Formatting and Encapsulation: Identifying both sender and receiver.
- Message Timing: Manages access methods and flow control.
- Message Size: Long messages are broken down into smaller parts to meet size restrictions.
Message Encoding Process
- Information is transformed into bits by the sending host.
- Bits are encoded into patterns of sounds, light waves, or electrical impulses based on the network medium.
Message Delivery
- Destination host decodes incoming signals to interpret the message.
- Proper delivery requires standard formats for letters and addressing.
Encapsulation
- The process of enclosing a message in a specifically formatted frame before it is sent over a network.
- A frame functions like an envelope, providing both destination and source addresses.
Handling Long Messages
- Long messages must be segmented into smaller pieces, each sent in its own frame.
- Each frame carries individual addressing information, allowing for proper reassembly by the receiving host.
Access Method
- Indicates when hosts should start sending messages and how to manage collisions that occur during transmission.
Flow Control
- Negotiates timing between source and destination hosts to prevent overwhelming receivers and confirm information receipt.
Response Timeout
- Rules dictate how long hosts should wait for responses and specify actions if a response is not received in the expected timeframe.

Communication Elements
- All communication methods consist of three elements: source (sender), destination (receiver), and channel (media).
- Rules or protocols are essential for effective communication.
Importance of Protocols
- Protocols ensure communication effectiveness through:
- Clearly identified sender and receiver.
- Use of a common language and grammar.
- Defined speed and timing of message delivery.
- Requirements for confirmation or acknowledgment.
Network Communication Protocols
- Network protocols define several key aspects:
- Message Encoding: Converting information into a format suitable for transmission.
- Message Delivery Options: Includes Unicast (one-to-one), Multicast (one-to-many), and Broadcast (one-to-all).
- Message Formatting and Encapsulation: Identifying sender and receiver with specific formats.
- Message Timing: Involves access method and flow control strategies.
- Message Size: Limitations necessitate segmenting long messages into smaller parts.
Message Encoding
- Messages are initially transformed into bits by the sending host.
- Each bit can be encoded through sounds, light waves, or electrical impulses depending on the channel used.
Message Decoding and Encapsulation
- The receiving host decodes signals to interpret the original message.
- Proper addressing is critical for successful delivery, facilitated by encapsulation:
- Encapsulation involves placing the message into a specific format called a frame.
- A frame contains the destination and source addresses, acting as an envelope for the message.
Handling Long Messages
- Just as humans break messages into sentences, network messages are also segmented into smaller frames for travel.
- Each frame is addressed independently, allowing the receiving host to reconstruct the original message from multiple frames.
Access Method and Flow Control
- Access Method: Determines when hosts may send messages and manage potential collision responses.
- Flow Control: Coordinated by source and destination hosts to maintain optimal timing and avoid information overload.
Response Timeout Rules
- Hosts abide by specific rules on waiting for responses, defining actions that follow a response timeout for efficient communication.
