Essential Protocols in Information Technology: Understanding Key Terminology

Essential Protocols In Information Technology

In the vast field of information technology, it is important to have a solid understanding of key protocols and terminology. This post provides a list of essential protocols and their descriptions, including WEP, SSH, FTP, HTTP, VLAN, VOIP, and more.

In the world of information technology, there are countless protocols and terminology to understand. However, not all of them are essential to know. This post will provide a comprehensive list of essential protocols and their descriptions, which will serve as a foundation for understanding other modules and expanding your knowledge in the field.

Understanding Key Terminology

The list includes well-known protocols such as Wired Equivalent Privacy (WEP), Secure Shell (SSH), File Transfer Protocol (FTP), Hypertext Transfer Protocol (HTTP), Server Message Block (SMB), Network File System (NFS), Simple Network Management Protocol (SNMP), Wi-Fi Protected Access (WPA), and more. Additionally, the list covers several advanced protocols, including Virtual Local Area Network (VLAN), Voice Over IP (VOIP), Extensible Authentication Protocol (EAP), and Internet Key Exchange (IKE).

By understanding these protocols and their functions, you can improve your knowledge and skills in the field of information technology, and specialize in one or two areas. Whether you’re a beginner or an experienced IT professional, this list will serve as a valuable resource in your career.

Network News Transfer ProtocolNNTPNNTP is a protocol used for distributing and retrieving messages in newsgroups across the internet.
Cisco Discovery ProtocolCDPIt is a proprietary protocol developed by Cisco Systems that allows network administrators to discover and manage Cisco devices connected to the network.
Hot Standby Router ProtocolHSRPHSRP is a protocol used in Cisco routers to provide redundancy in the event of a router or other network device failure.
Virtual Router Redundancy ProtocolVRRPIt is a protocol used to provide automatic assignment of available Internet Protocol (IP) routers to participating hosts.
Spanning Tree ProtocolSTPSTP is a network protocol used to ensure a loop-free topology in Layer 2 Ethernet networks.
Terminal Access Controller Access-Control SystemTACACSTACACS is a protocol that provides centralized authentication, authorization, and accounting for network access.
Session Initiation ProtocolSIPIt is a signaling protocol used for establishing and terminating real-time voice, video and multimedia sessions over an IP network.
Voice Over IPVOIPVOIP is a technology that allows for telephone calls to be made over the internet.
Extensible Authentication ProtocolEAPEAP is a framework for authentication that supports multiple authentication methods, such as passwords, digital certificates, one-time passwords, and public-key authentication.
Lightweight Extensible Authentication ProtocolLEAPLEAP is a proprietary wireless authentication protocol developed by Cisco Systems. It is based on the Extensible Authentication Protocol (EAP) used in the Point-to-Point Protocol (PPP).
Protected Extensible Authentication ProtocolPEAPPEAP is a security protocol that provides an encrypted tunnel for wireless networks and other types of networks.

Microsoft Baseline Security AnalyzerMBSAIt is a free security tool from Microsoft that is used to detect potential security vulnerabilities in Windows computers, networks, and systems.
Supervisory Control and Data AcquisitionSCADAIt is a type of industrial control system that is used to monitor and control industrial processes, such as those in manufacturing, power generation, and water and waste treatment.
Virtual Private NetworkVPNVPN is a technology that allows users to create a secure, encrypted connection to another network over the internet.
Internet Protocol SecurityIPsecIPsec is a protocol used to provide secure, encrypted communication over a network. It is commonly used in VPNs, or Virtual Private Networks, to create a secure tunnel between two devices.
Point-to-Point Tunneling ProtocolPPTPIt is a protocol used to create a secure, encrypted tunnel for remote access.
Network Address TranslationNATNAT is a technology that allows multiple devices on a private network to connect to the internet using a single public IP address. NAT works by translating the private IP addresses of devices on the network into a single public IP address, which is then used to connect to the internet.
Carriage Return Line FeedCRLFCombines two control characters to indicate the end of a line and a start of a new one for certain text file formats.
Asynchronous JavaScript and XMLAJAXWeb development technique that allows creating dynamic web pages using JavaScript and XML/JSON.
