TCP and UDP are part of the TCP/IP protocol suite, which is what most networks nowadays are built upon (including the Internet). They are sets of rules that govern how data is transported between computers, a language if you will. TCP stands for Transmission Control Protocol and UDP for User Datagram Protocol. TCP requires a connection to transmit data, whereas UDP is not a connection-oriented protocol (requiring less processing overhead).

Basically, A TCP/UDP port is a virtual port that is opened by your operating system on your computer. Ports may be numbered anything between 0 and 65536. A port may be open, closed, or listening for incoming connections. For example, every time you request a webpage, your Internet browser sends a request to the target server on TCP port 80, which is the port most web servers listen on. That web server will then send back information to an ephemeral port on your computer (meaning, semi-randomly allocated). To make this post relevant to Halo, the game listens on UDP 2302 and connects to game hosts on TCP 2303. It also checks for updates on the standard port 80 (http).

If you want to see a list of ports that are open/listening on your computer right now, open a run command (Start button-->Run...) and type "cmd" without the quotes. Once the command prompt is open, type "netstat -a", again, without the quotes. Most personal firewalls will also display a list of open and listening ports.

Much more information can easily be found on TCP/UDP by playing with a search engine. In fact, this is not a subject that can easily be explained. You have to put some effort into learning this stuff for yourself.
