Understanding Network Protocols & Communications

📡 Network protocols and communication are essential in computer networks.

💻 Data communication involves the exchange of data between two nodes.

🔁 There are three types of data flow: simplex, half-duplex, and full duplex.

Half-duplex communication allows for communication in both directions but not at the same time.

Full-duplex communication enables communication in both directions simultaneously.

Simplex communication involves data transmission in only one direction.

💡 Protocols are rules that govern communication and ensure effective data transmission.

🗣️ Human communication requires a common language, grammar, and proper timing for effective delivery.

🤝 Mutual agreement on rules is necessary to avoid chaotic or ineffective communication.

💡 Protocols are essential for effective network communication.

⏱️ Timing and message size play a crucial role in network communication.

📦 Protocols involve message encoding, formatting, encapsulation, and delivery options.

💡 Different mediums require different methods of data transmission.

🌐 Message encoding involves converting data into signals or waves depending on the medium.

📦 Message formatting and encapsulation are used to identify the sender and receiver of the data.

📏 Message sizing is an important factor to consider for effective communication.

⭐ Network protocols break messages into smaller units for transmission.

🔀 Flow control is essential in ensuring effective communication between sender and receiver.

⏱️ Protocols determine the timing for acknowledging received data and retransmitting if needed.
