Chapter 7 Telecommunications, the Internet, and
Wireless Technology
1) Telephone networks are fundamentally different from computer networks.
2) Wikis allow visitors to change or add to the original posted material.

4) A hub is a networking device that connects network components and is used to filter and
forward data to specified destinations on the network.
5) In a client/server network, a network server provides every connected client with an address
so it can be found by others on the network.

on the Internet.
18) Mobile search makes up 20% of all Internet searches.
19) RFID technology is being gradually replaced by less costly technologies such as WSNs.
20) Software-defined networking (SDN) is a new networking approach in which many of these
control functions are managed by one central program, which can run on inexpensive
commodity servers that are separate from the network devices themselves.
21) Client/server computing is a distributed computing model in which some of the processing
power is located within small, inexpensive client computers and resides literally on
desktops, laptops, or handheld devices.

22) The Transport layer enables client application programs to access the other layers and
defines the protocols that applications use to exchange data.
23) The Application layer is responsible for providing the Application layer with
communication and packet services.
24) The Network Interface layer is responsible for addressing, routing, and packaging data
packets called IP datagrams.
25) The Internet layer is responsible for placing packets on and receiving them from the
network medium, which could be any networking technology.
26) A digital signal is a discrete, binary waveform, rather than a continuous waveform. Digital
