What is the X in X-mas?
A system connecting computers around the world using TCP/IP, which stands for Transmission Control Protocol/Internet Protocol, a set of standards for transmitting and receiving digital data. The Internet consists primarily of the collection of billions of interconnected webpages that are transferred using HTTP (Hypertext Transfer Protocol), and are collectively known as the World Wide Web. The Internet also uses FTP (File Transfer Protocol) to transfer files, and SMTP (Simple Mail Transfer Protocol) to transfer e-mail.
The global communication network that allows almost all computers worldwide to connect and exchange information. Some of the early impetus for such a network came from the U.S. government network Arpanet, starting in the 1960s.
Note: Some scholars have argued that the access to massive amounts of information, together with the widespread ability to communicate, has altered the way that human beings perceive reality.
