How is your computer connected to another computer on the internet?

Answer 1

The switch itself. It sounds like the switch may be having a conflict between any two given NICs. And as for plugging the modem directly into computer #2, did you use a cross-over cable or just a straight cat5? Because if you are connecting anything (two computers, one computer to a modem etc.)without going through a switch or a router, you must use cross-o

Answer 2

This question is sadly very vague. There are a variety of methods involved in connecting computers over the internet. The simplest method is merely to host a server application on one of the computers. The Internet IP address of this computer can then be obtained from WhatIsMyIP (linked below) and other computers can use that IP to connect to the server being hosted (which may be a Web server, telnet server, e-mail, FTP, or whatever else)

To connect two or more computers in a LAN-style configuration over the Internet, the freeware program Hamachi is very useful. You can download it below - install it on all the computers, then use it to create a network. Have all the computers join the network, and BAM! Instant ability for LANning! Communication may be set up between computers using instant messengers or IRC applications - these allow for "humanised" communications.

Answer 3

The internet itself is computers connected to other computers. I will explain how a computer connects to another computer through the internet using remote desktop.

When a request for access to another computer over the internet there is a series protocals and authentications that has to be proccesed before a valid secure connection is established First you must have a etablished internet connection with your ISP servers. After that you will be assined a IP address and that is what you use to identify yourself. For a standard home computer you must know the partys IP address that you want to connect to. When the request is sent, compA must be able to passthrough the outbound Firewall. For example Remote Desktop uses port: 3389, When this port is avalible the program sends a packet of information contaning your ip address, the path withch is the port, and what the program wants to be asked. The packet can be very many smaller packets. Depending on the location of computerB these packets can pass through 100s of servers and thousands of miles before reaching computerB. through this proccess it is authenticated to pass through each one. When the packets reaches the host computer (computerB) is comes in through the modem witch passes through the router and looks for the IP that it wants to come through and is authenticated. Soon after the packet reaches the host, it becomes authenticated to pass though the port declared by the firewall inbound rules. After that it checks the computers local security policy to make sure that someone outside of the network can have access to remote desktop. Soon after it sends a packet back to computerA asking for credentials (user name and password) and is sent back to compB. When the security protocals are passed and the secure connection is esblished it is free to transfer information as long as till the connection is broken or denied.
