communications signals.
3) Allows participants to have the ability to open a separate window and type messages
to one another.
4) Kind of network that is sometimes called a file sharing network.
5) Transmission media that sends communications signals through the air or space
using radio, microwave, and infrared signals.
6) Consists of a single copper wire surrounded by at least three layers.
7) A network standard that specifies how two devices use short-range radio waves to
communicate at high speeds with each other.
8) Kind of cable designed to reduce noise.
9) Some industry experts predict that this will replace infrared technology.
10) Mobile computers and devices, such as a mouse, printer, and smart phone, often
have this kind of port to enable the transfer of data from one device to another using
light waves.
11) A wireless transmission medium that distributes radio signals through the air over

14) A form of broadcast radio that is used widely for mobile communications.
15) To prevent unauthorized users from accessing files and computers, many routers are
protected by these.
16) Category of cellular transmission that transmits digital data at speeds from 9.6 Kbps
to 19.2 Kbps.
17) Examples of standards in this category include GSM and UMTS.
18) Can be negatively affected by the distance between two points, the type of
transmission media, and the number of nodes through which data must travel.
19) The core of this kind of cable consists of dozens or hundreds of thin strands of glass
or plastic that use light to transmit signals.
20) Category of cellular transmission that transmits digital data at speeds up to 15
Mbps.
