Hypertext Transfer Protocol Secure (HTTPS) is a widely used communications protocol for secure communication over a computer network, with especially wide deployment on the Internet. Technically, it is not a protocol in itself; rather, it is the result of simply layering the Hypertext Transfer Protocol (HTTP) on top of the SSL/TLS protocol, thus adding the security capabilities of SSL/TLS to standard HTTP communications. The Secure Socket Layer (SSL) and Transport Layer Security (TLS) is the most widely deployed security protocol used today. It is essentially a protocol that provides a secure channel between two machines operating over the Internet or an internal network. In today's Internet focused world, the SSL protocol is typically used when a web browser needs to securely connect to a web server over the inherently insecure Internet.
The most popular example of UDP protocol usage is video streaming such as Youtube, Twitch, etc.
Take a look at any definition for TCP protocol. Most are also written in C.
TCP
A hypertext protocol is a protocol relating to hypertext. The most well-known hypertext-related protocol would be the Hypertext Transfer Protocol, which is used to transfer hypertext from one machine to another.
The most common two are TCP (transmission control protocol) and UDP (user datagram protocol)
TCP and UDP Correct: UDP (User Data-gram Protocol) is a communications protocol that offers a limited amount of service when messages are exchanged between computers in a network that uses the Internet Protocol. UDP provides two services not provided by the IP layer. It provides port numbers to help distinguish different user requests and, optionally, a checksum capability to verify that the data arrived intact. TCP (Transmission Control Protocol) is a set of rules (protocol) used along with the Internet Protocol (IP) to send data in the form of message units between computers over the Internet. While IP takes care of handling the actual delivery of the data, TCP takes care of keeping track of the individual units of data (called packets) that a message is divided into for efficient routing through the Internet. (TCP/IP) is the know definition by most.

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.
Most modern operating systems (Windows, Linux, Unix, mainframes) support SSH and SSL.
IP, the Internet Protocol. It handles routing and package transfer between internet participants. The http- hyper text transfer protocol may be used to view websites. This part of the internet is called the "world wide web" or "www".
