IP Address: An Internet Protocol Address is a numerical label assigned to each device participating in a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: A name indicates what we seek. An address indicates where it is. A route indicates how to get there.
HTTP: The acronym for Hyper Text Transfer Protocol, the underlying protocol used by the World Wide Web. HTTP defines how messages are formatted and transmitted, and what actions web servers and browsers should take in response to various commands. For example, when you enter a URL in your browser, this actually sends an HTTP command to the web server, directing it to fetch and transmit the requested web page.
Latency: Latency is simply defined as the time delay observed as data transmits from one point to another. Usually, to determine network latency the origin and destination points are used. A so-called low-latency network connection is one that generally experiences small delay times, while a high-latency connection generally suffers from long delays. 500-ms latency is widely used as the limit for speech.
SIP: Session Initiation Protocol, a very simple text-based application-layer control protocol. It creates, modifies, and terminates sessions with one or more participants.
UDP: Universal Datagram Protocol, a protocol to transfer sequential data over data networks.
URL: Uniform Resource Locator, the technical name for the address where a specific web page is found.
