SVGA Module Review Introduction to Networking 63 M o d u l e 2 %CTTKGT5KIPCNU%CDNG6[RGUCPF0GVYQTM 6QRQNQIKGU 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. Introduction to Networking 67 T e r m s a m p l i t u d e —Amplitude is the height of a wave, or how far from the center it swings. a n a l o g —A signal transmitted as a pattern of continually changing electromagnetic waves is referred to as an analog signal. A m e r i c a n N a t i o n a l S t a n d a r d s I n s t i t u t e ( A N S I ) —ANSI is a U.S. voluntary organization that develops and publishes standards for data communications, programming languages, magnetic storage media, office systems, and encryption. ANSI represents the United States as a member of ISO and IEC. a s y n c h r o n o u s —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. b a c k b o n e —A backbone is the portion of a network that carries the most significant traffic. It is also the part of the network that connects many smaller networks to form a larger network. b a n d w i d t h —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. b a s e b a n d —Baseband is a form of digital modulation in which one signal takes up the entire available bandwidth of the communication channel. b i n a r y —Binary refers to the base 2 numbering system used by computers to represent information. Binary numbers consist of only two values: 1 and 0. In a binary number, each position is two times greater than the position to its right. b i t —A bit, also referred to as a binary digit, is a single value that makes up a binary number. A bit can be either 1 or 0. See binary. B N C c o n n e c t o r —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.
