*Direct optical connection via suppliers will have a terminator in the premises and can offer gigabit speeds or above.

*Cable connection links you to your cable company, which provides you with many (though not all) of the same services as a traditional ISP. The speed of transmission over a cable network can vary widely (from quite fast to very slow) based in part on the usage within your neighborhood.

*4G and soon 5G connection over the mobile network is an option in some rural situtations that are outside the reach of fast physical connections.

*Satellite connectivity: connection either one way (down only, with up over a physical link) or more commonly now two-way. This has had the problem of high latency when used with geo-stationary satellites. New low-earth satellite constellations are becoming available that solve this issue.
'''Dial-up'''
* Where all else fails, connection can be via dialup modems. With dialup connectivity, your server is not usually permanently connected to the Internet. Rather, it connects to your ISP over a phone line using a modem or ISDN adapter . Because your connection to the Internet is not permanent, some of the services on your server cannot be provided to the outside world. For example, having your server host your external company web site would create a problem because whenever your server was not connected to the Internet, the web site would not be available. (However, it could certainly host an intranet web site because the local network would always be connected.)
