Today we learned about different physical ports on a computer. These are the actual ports for video, audio and the other peripherals your common in a modern day computer. For example video can use VGA, DVI, HDMI or a Display port. Parallel ports such as DB9 and DB25 has mostly been replaced by either USB or serial ports. Some ports are also in the decline such as Firewire.
We also learned about looking closely at the information in the Uniform Resource Locator (URL) in the browser address bar which contains the protocol, domain name, sub-domain and other resources. The information use delimiters to separate information known as comma separated values (CSV) and may contain name value pairs for sending and receiving data through the web.
