What are TCP, UDP, Proxy, port, local host, ip address?

TCP and UDP are simply put two ways of sending data from one place to another.\nTCP ensures that the data you get is always right, so it does a lot of checks for you. That makes TCP connections a bit slow.\nUDP tried to make the data reach you as fast as possible. It sometimes makes small mistakes because of being in such a hurry\nI would suggest that if you are downloading text documents like ebooks etc. use TCP\nIf you are listening to songs, use UDP (you will not even notice the difference of sloppy delivery)\n\nProxy (Server) is a large computer that does the surfing for you. So assume that you want to go to yahoo.com, yahoo will find it very hard to handle all the people who want to see yahoo.com at the same time. A proxy server can then visit it for say 100 people and next time, if you ask for yahoo.com, it can send you the page all by itself (so yahoo is not overloaded) and you think the service is faster. \n\nIP address is a way all the computers connected in the internet identify themselves. Each computer is given 1 unique IP address (much like we all have postal addresses). So if you know the IP address of each computer, its easier to reach that computer, rather than meander arounding asking people whether they know where this computer is connected. An IP address looks like 192.168.12.234\n\nPort is like an electric socket at your home. Assume that you hv two TVs at your place, and both are tuned to different channels. So even if the channels knew that they are broadcasting the stuff to the same house (or IP address), they know that eventually it goes to two different sockets (or ports). Your computer has one IP address, but multiple ports. These port are numbers like 80, 3012 etc\n\nI am simplifying all these terms for you to understand. I will recommend that you talk to your ISP or a local "computer-expert" to help you identify the exact proxy, IP address, port etc for you.\n\nAll the best!

What you are looking for are the environment variables.  These are most often collected when a form is submitted and can be logged or emailed.\n\nAn example:\nREMOTE_ADDR contains the user IP address

Well if you are sitting at the computer then entering ipconfig /all at the command prompt will tell you what you want to know.  The link below will tell you your public IP address if you are using some sort of address translation.

The application layer of TCP/IP is the layer where applications gain access. There are many standards TCP/IP utilities and services at the Applications layer such as FTP, Telnet, SNMP and DNS. \nMicrosoft TCP/IP provides two interfaces for network applications. Windows sockets-standard application programming interface (API) under Microsoft Windows for transport protocols such as TCP/IP and IPX.

Network Connections>(your wireless network)>Properties\nIt should be listed right there, otherwise it is the routers IP address mentioned in the manual.

proxy server is a computer that offers a computer network service to allow clients to make indirect network connections to other network services. A client connects to the proxy server, then requests a connection, file, or other resource available on a different server.\n\nIn other words its more or less like a BARRIER between the end computer and the internet.\nExample-> Your PC -> PROXY SERVER -> Internet\nThe proxy server has the ability to monitor every request, incoming and outgoing.

Just go to the command prompt (on windows XP just type CMD on the START > RUN) and type ping website.com . you will get the IP address. or You can go to dnsstuff.com which can do a whole lot of other things than just getting the IP address.

check your network/proxy settings

ok, all you do is go onto command prompt and type in "ping xxx.xxx.xxx", wer xxx.xxx.xxx is watever your friend's ip address is. Then, it will come up with a whole bunch of info and stuff.\n\nalso, if you type in "ping/exe", it gives you a key to some of the acronymes

You can use Ethereal to capture the packets from just before the game starts up to a bit into the game.  Then look at the capture.  It'll tell you what is running on what port, the protocols, etc.

Check your IP settings. click start, run, control panel and select network connections.  right click on  local area connection.  find internet protocol in the list and double click it.  you should be using DHCP (Obtain IP address Automatically and Obtain DNS server address automatically)

the first group of four x's are the IP address itself; the four x's after the ip address are the port number.\n\n127.0.0.1:80 would be the localhost Web server default port;\n\n127.0.0.1:21 would be the localhost default FTP port;\n\netc.

ARP - \n\nAddress Resolution Protocol. A TCP/IP protocol used to convert an IP address into a physical address, such as an Ethernet address. A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP network. The host on the network that has the address in the request then replies with its physical hardware address. Precidia's products support ARP.\n\nUDP -\n\nUser Datagram Protocol. A communications protocol for the Internet network layer, transport layer, and session layer, which makes it possible to send a datagram message from one computer to an application running in another computer. Like TCP (Transmission Control Protocol), UDP is used with IP (the Internet Protocol). Unlike TCP, UDP is connectionless and does not guarantee reliable communication; the application itself must process any errors and check for reliable delivery

If you are on a LAN and u know the hostname,\nyou can type\n\nping  (hostname)\n\nYou'll get response as\n\nReply from <IP address>

You don't need instructions for TCP/IP. TCP/IP is the communication method your computer uses to talk on the Internet. Don't mess with it at all.

a proxy goes between your computer and the internet, or your network, and an ip address is the number given to identify your computer online, by your isp.\n\nSo a proxy ip address is like using someone elses address for your time online instead of your own...
