4. Briefly explain how the converging of media content on the Internet, from movies to books to
music, came about.
1. Name a group that worked to establish the early Internet. Explain the motivation for
developing the Internet.
The Internet originated as a military-government project, with computer time-sharing
as one of its goals. In the 1960s, computers were relatively new, and there were only
a few of the expensive, room-sized mainframe computers across the country for
researchers to use. The Defense Department’s Advanced Research Projects Agency
(ARPA) developed a solution to enable researchers to share computer processing
time beginning in the late 1960s. This original Internet—called ARPAnet and
nicknamed the Net—enabled military and academic researchers to communicate on a
distributed network system. First, ARPA created a wired network system in which
users from multiple locations could log into a computer whenever they needed it.
Second, to prevent logjams in data communication, the network used a system called
packet switching, which broke down messages into smaller pieces to more easily
route them through the multiple paths on the network before reassembling them on
the other end.
2. Many experts agree that one of the major characteristics that make the Internet unique is that it
cannot be centrally controlled. Explain why and how this came about.
In a centralized network, all the paths lead to a single nerve center. Decentralized
networks contain several main nerve centers. In a distributed network, which
resembles a net, there are no nerve centers; if any connection is severed, information
can be immediately rerouted and delivered to its destination. Ironically, one of the
most hierarchically structured and centrally organized institutions in our culture—the
national defense industry—created the Internet, possibly the least hierarchical and
most decentralized social network ever conceived. Each computer hub in the Internet
has similar status and power, so nobody can own the system outright, and nobody has
the power to kick others off the network. There isn’t even a master power switch, so
authority figures cannot shut off the Internet—although some nations and
corporations have attempted to restrict access for political or commercial benefit.
3. Briefly describe how digital communication has progressed from e-mail.
Although e-mail remains a standard for business-related text communications in the
digital era, it has been surpassed in popularity by social apps, which include
Facebook, Instagram, Snapchat, and Twitter.
