Document Summary
Where you want to go - uniform resource locator. From what host (i. e. an ip or name of a machine) should the web page be downloaded? occasionally have to specify the port when we want it to be something other than the default. The first few characters preceding the colon indicate what protocol should be used for the network conversation. Another common alternative is https, which uses http over a secure connection. Provides the dual benefits of making eavesdropping very difficult and of validating that you"re really connecting to the server that you think you are. After the colon and the two slashes is the host. Www. ics. uci. edu, machine on which the ics website is hosted. It is also possible to specify a port, by following the host with a colon and a port number (eg: www. ics. uci. edu:8080) The default port number for http traffic is 80.
