IP Sec, SSL, TLS
The commonly used protocols are the TCP/IP protocol suite. This is a set of protocols that work together, not a single protocol.
IGRP and RIPv1
Elementary data link protocols must agree at the most rudimentary level. The data frame must be constructed from this level, and all protocols must agree.
As many as you can select/install. You can in theory run all protocols on most modern operating systems, but you generally only need one now a days, and that is TCP/IP.
The Transmission Control Protocol (TCP) provides the most error-handling capabilities among networking protocols.

The two that are most commonly used are called TCP and UDP.
SSL (Secure Socket Layer,) is a protocol. Most Cisco VPNs will use SSL as their security protocol, so there is no difference between Cisco VPN and SSL VPN.
You probably noticed that there are a lot of VPNs available in the market. In fact, there are currently more than 300 VPNs available.

Web browsers and web servers communicate using protocols, the most common of which is the Hypertext Transfer Protocol (HTTP). This set of rules defines how messages are formatted and transmitted over the internet. Other related protocols include HTTPS (HTTP Secure) for secure communication and WebSocket for real-time data exchange. These protocols ensure that data is properly requested, transmitted, and displayed to users.
The most secure method of sending information over the web is to use end-to-end encryption (E2EE), which ensures that only the communicating users can read the messages. Protocols like Signal or WhatsApp utilize E2EE to protect data from interception during transmission. Additionally, using secure protocols such as HTTPS, which encrypts the data between the user and the server, further enhances security. Regular software updates and strong password practices also help maintain overall security.

Distance vector protocols compute their routing tables before sending routing updates; link-state protocols do not.
TCP/IP is a "protocol suite", i.e., a group of related protocols, protocols that work together. It is named after two of the most important protocols, TCP and IP - but the TCP/IP stack is made up of many more protocols, it is not just those two.TCP/IP is a "protocol suite", i.e., a group of related protocols, protocols that work together.

Session Initiation Protocol (SIP) is the most commonly used VoIP signalling protocol. Due to its scalability, cross-compatibility and open nature, SIP has become the protocol of choice for VoIP signalling. H.323 is another commonly used protocol.
