We will begin considering the physical qualities of the network itself by discussing the
nature of electronic communication and explaining how information can be transmitted
as an analog or a digital signal. We then explore the various physical layouts or
topologies of data networks and show how the pattern of signal flow depends on the
topology of the network.
We then describe the characteristics of the three main types of physical transmission
media used in networks: copper cable, fiber optic cable, and wireless communication
(radio waves). We learn how signals travel over each media, and their relative
advantages and disadvantages.
As you work through this module, it is important to remember that there is no “best”
network topology or physical medium. A network designer’s choice of topology and
cabling (or lack of it) is determined by the type of work the network must do, and the
type of physical environment it must work in.

organization that develops and publishes standards for data communications,
programming languages, magnetic storage media, office systems, and

—Asynchronous operation means that bits are not transmitted
on any strict timetable. Transmitting a start bit indicates the start of each
character. After the final bit of the character is transmitted, a stop bit is sent,
indicating the end of the character. The sending and receiving modems must
stay in synchronization only for the length of time it takes to transmit the 8
bits. If their clocks are slightly out of synch, data transfer will still be successful.

—Bandwidth is a measure of the information-carrying capacity of a
channel. In analog networks, bandwidth is the difference between the highest
and lowest frequencies that can be transmitted across a communication link.
Analog networks measure bandwidth in cycles per second (Hz). Digital
networks measure bandwidth in Kbps, Mbps, and Gbps.

—BNC connectors are small devices used to connect
computers to a thin coaxial cable bus (10Base2) or terminate the ends of a
bus. There are several different types of BNC connectors. A BNC barrel
connector joins two Thinnet cables. A BNC terminator is used to terminate
the end of a cable. It acts as a resistive load that absorbs the signal that
reaches one end of the bus. (Two terminators are needed on each bus.) BNC
adapters connect different types of cable, such as Thinnet to Thicknet.
