Study Notes

Network Protocols Overview

Network protocols regulate device communication and data exchange over networks.
They establish rules for message format, sequence, and meaning of exchanged data.
Protocols allow for standardized connections, data transmission, and reliable communication across various technologies.

Key Features of Network Protocols

Message Format: Defines the structure and organization of messages, including data element order and control information.
Addressing: Assigns unique addresses to devices, detailing how these addresses are utilized during communication.
Handshaking and Connection Establishment: Involves a negotiation process that verifies both devices are prepared to communicate and agree on session parameters.
Error Detection and Correction: Incorporates algorithms like checksums or parity bits to identify transmission errors and initiate data retransmission if needed.
Flow Control: Manages data transmission rates to prevent the receiving device from being overwhelmed by incoming data.
Routing: Determines the most efficient pathways for data transmission across networks.
Security: Encompasses measures to protect data confidentiality and integrity, including encryption, authentication, and access control mechanisms.
