HTML commands include instructions to make text bold or italic, or to link to other sites.

Hypertext Transfer Protocol Secure (HTTPS) This is a protocol used to transfer data over the Internet and other networks in a secure fashion by encrypting data. It provides protection from hackers. It can authenticate (verify) that the network connected to is not spoofed, meaning it is the network that it purports to be and that another network has not intercepted a communication intended for a different site.
