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.
