Exam 7: Networks and Communication Devices

In ____, data is sent when it is ready but all data must be delivered at the time that it is needed.

____ is relatively uncommon in data transmissions because most devices that are mainly one-directional, such as a printer, can still transmit error messages and other data back to the computer.

The trend toward online collaboration is usually called workgroup computing.

TCP/IP uses  packet switching to transmit data. _________________________

Conventional telephone systems use digital signals.

Similar to Wi-Fi, ____ is designed to provide Internet access to fixed locations (sometimes called hotzones), but the coverage is significantly larger.

With a(n) ____________________ topology, each device on the network is connected to every other device on the network.

____ is the use of computers, video cameras, microphones, and networking technologies to conduct face-to-face meetings over a network.

In ____, data can travel in either direction, but only in one direction at a time.

A(n) ____________________ is a network that covers a large geographical area.

A(n)  ring network  uses a central cable to which all network devices connect. _________________________

With ____, data is sent one bit at a time, one after the other along a single path.

Technically, to be called a ____, a device must convert digital signals (such as those used by a computer) to modulated analog signals (such as those used by conventional telephone lines) and vice versa.

Transferring data from a client to a server is called downloading.

There must be 24 GPS satellites in orbit at any given time in order to have at least ____ satellites in view from anywhere on the planet.

____ transmissions are radio signals sent to and from cell phones via cellular (cell) towers.

A coaxial cable is a networking cable consisting of wire strands twisted in sets of two and bound into a cable.

When parallel transmission is used, a group of bits are sent at the same time, and each bit takes a separate path.

Support for TCP/IP is built into operating systems, and TCP addresses are commonly used to identify the various devices on computer networks. _________________________

____ satellites travel at a speed and direction that keeps pace with the earth's rotation, so they appear (from earth) to remain stationary over a given spot.
