Study Notes

Email Protocols

Simple Mail Transfer Protocol (SMTP) facilitates email message exchange between computers and servers over a network, commonly used by Gmail and Outlook.
Post Office Protocol (POP3) enables one-way email synchronization, allowing users to download emails to a single device.
Internet Message Access Protocol (IMAP) allows multi-device email retrieval via TCP/IP, enabling more dynamic email management.

Network Management

Simple Network Management Protocol (SNMP) is an application-layer protocol for managing network devices like routers and printers, part of TCP/IP suite.
SNMP collects and organizes information from network devices, allowing modifications to device behavior.

Domain Name System (DNS)

DNS operates through generic, country, and inverse domains for internet resource identification.
Country domains use two-character country codes (e.g., "us" for the United States), while generic domains use three-character organization labels.
Inverse domain mapping is used to associate IP addresses with domain names.

File Transfer Protocol (FTP)

FTP facilitates file transfers over the internet, allowing uploads, downloads, and cloud storage.
Internet connection is required for FTP operations, widely used by individuals and businesses for website maintenance.
Common FTP clients include FileZilla, Core FTP, and WinSCP.

Network Security

Kerberos is a network authentication protocol developed by MIT to ensure secure client/server communication through secret-key cryptography.
Key components of Kerberos include User/Client, Key Distribution Center (KDC), Authentication Server (AS), and Ticket-Granting Server (TGS).
Kerberos mitigates security issues within networks, authenticating users and servers throughout the process.

General Networking Protocols

User Datagram Protocol (UDP) is a transport layer protocol utilized for fast communication without connection establishment.
Request for Comments (RFC) documents, published by the Internet Engineering Task Force (IETF), specify technical standards for internet protocols and services.
Reverse Address Resolution Protocol (RARP) assists devices in local area networks (LAN) in acquiring their IP addresses based on physical addresses.
