Remote Address

This is the IP address, in this situation, the public IP address, from which you are connecting to this site's HTTP server.

IP addresses are 32-bit binary numbers expressed in dotted decimal notation. "01111111000000000000000000000001" is the binary representation of the IP address of your computer's/device's (etc.) loopback interface. That number in dotted decimal notation is "127.0.0.1".

This is the SSI HTTP environment variable REMOTE_ADDR.

Remote Port

This is the port from which you are connecting to this site's HTTP server.

Ports are 16-bit binary numbers expressed in decimal as unsigned integers. This number will likely be between 1024 and 65535 or between 32768 and 65535 depending on your operating system.

This is the SSI HTTP environment variable REMOTE_PORT.

User Agent

This is the identifier for your browser and its version. It also may include information about the platform (computer/device, etc.) it's running on such as the operating system and version as well as the CPU's architecture family.

CPU: Central Processing Unit. Primary control center of a computer/device (etc.), which in the context of a computer, could refer to the main housing for the main processor/processors or the main processor/processors specifically.
CSV: Comma-Separated Values. A comma delimited text file often used for spreadsheets.
GMT: Greenwich Mean Time. The mean solar time since midnight at the Royal Observatory in London (Greenwich), England. Similar to, but not the same as Universal Coordinated Time (UTC). GMT is a time zone while UTC is a time standard. GMT is the same as UTC±00:00 whereas PST is the same as UTC-08:00.
HTML: Hypertext Markup Language. A markup language used to create webpages.
HTTP: Hypertext Transfer Protocol. The rules and methods that govern the transmission of web content. In both the IP suite and the Open Systems Interconnection (OSI) model, HTTP is in the application layer.
HTTPS: Hypertext Transfer Protocol Secure. Identical to HTTP but served over a secure channel using Secure Sockets Layer (SSL) or Transport Layer Security (TLS). Also known as HTTP over SSL or HTTP over TLS respectively.
IP: Internet Protocol. The rules and methods that govern the transmission of data between computers/devices (etc.). It is the underlying technology upon which the Internet, and by extension the World Wide Web, runs.
JSON: JavaScript Object Notation. Like Extensible Markup Language (XML), but a data format rather than a markup language, a way to share data between various applications, like, but not limited to, browsers or between webpages/websites.
MIME: Multipurpose Internet Mail Extensions. A model for defining types and subtypes of media for displaying or serving content in e-mail, the World Wide Web, and more.
SSI: Server Side Includes. A server-side interpreted scripting language used for webpages.
UTC: Coordinated Universal Time (ask the International Telecommunication Union why the acronym is what it is). A time standard for coordinating time universally, based on International Atomic Time (TAI, ask the International Bureau of Weights and Measures why the acronym is what it is) with adjustment for leap seconds. The GMT time zone isn't the same as, but is similar to, UTC... in a way.
XHTML: Extensible Hypertext Markup Language. Like HTML but with the strict formatting rules of XML.
XML: Extensible Markup Language. Like HTML but with stricter formatting rules. While HTML is intended for browser to display content, XML is meant to be for sharing data between various applications, like, but not limited to, browsers or between webpages/websites.
