3 Moving Data: Bandwidth and Modems Communications is the method of sending and receiving messages electronically between two points. Communication channels are the paths through which messages are passed from one location to another. Communication occurs over communication channels. Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 7 Moving Data: Bandwidth and Modems Data movement over communication channels is performed through analog and digital signals. Analog signals obtain and translate data into continuous waveforms. Digital signals change data into discrete, discontinuous pulses. Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 8 Moving Data: Bandwidth and Modems Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 9 3

4 Moving Data: Bandwidth and Modems The maximum amount of data transmitted through a communication channel is referred to as bandwidth. Broadband is any transmission medium transporting large amounts of data at high speeds. Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 10 Moving Data: Bandwidth and Modems Communication devices that enable data transmission over telephone lines are known as modems. Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 11 Moving Data: Bandwidth and Modems Modulation is the transformation of digital signals into analog signals. Demodulation is the transformation of analog signals into digital signals. The data transfer rate, the rate at which two modems exchange data, is measured in bits per second (bps). Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 12 4

5 Transmission Media Wired transmission media use solid forms, such as twisted-pair, coaxial, and fiber-optic cables, to transmit data. Wireless transmission media send data through the air or space by means of infrared, radio, or microwave signals. Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 13 Transmission Media Twisted-pair cables transmit data using four insulated twisted wires that shield against electromagnetic interference. Coaxial cables transmit data and consist of a center copper wire surrounded by a layer of braided wire. Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 14 Transmission Media Fiber-optic cable is made up of thin strands of glass or plastic that carry data through pulses of light. The infrared wireless transmission medium carries data through the air using light beams. Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 15 5

6 Transmission Media Radio transmissions enable data in such forms as music, photos, and voice conversations to travel through the air as radio frequency or radio waves. Bluetooth is a short-range radio transmission technology that enables devices within 30 feet of each other to communicate wirelessly. Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 16 Transmission Media Microwaves transmit data and are high-frequency electro-magnetic radio waves with very short frequencies. Satellites are microwave relay stations in space that transmit data through microwave signals to and from Earth-based stations. Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 17 Transmission Media Direct Broadcast Satellite (DBS) is a consumer satellite technology that receives digital TV signals through the use of a reception dish. Computer systems using wireless transmission media require devices for communication called network access points. Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 18 6

7 Wired Communication via the The public switched telephone network (PSTN), a worldwide telephone system, is an immense network used for data and voice communications. A subscriber loop carrier (SLC) is a curbside installation that connects subscribers. A local loop is the area served by an SLC. Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 19 Wired Communication via the Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 20 Wired Communication via the Multiplexing is a technique that enables sending more than one call over an individual line. Last-mile technologies provide solutions for bottlenecks that result from the inability of users to access the PSTN s high-speed fiber-optic cables. Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 21 7

8 Wired Communication via the Integrated Services Digital ing (ISDN) is the standard that makes digital telephone and data service available. Connecting computers to ISDN lines requires an ISDN adapter/digital modem. With ISDN, there is no extended dial-in or connection delay. Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 22 Wired Communication via the Digital Subscriber Line (DSL) is the broad term for a group of technologies that offer high-speed access to the Internet. A DSL modem is required to modulate and demodulate analog and digital signals. Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 23 Wired Communication via the Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 24 8

9 Wired Communication via the A cable modem is a tool that gives a computer the ability to access the Internet through cable TV connections. Leased lines enable continuous endto-end communication between two points through specially conditioned telephone lines, such as T1 lines. Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 25 Wired Communication via the Last-mile technologies include: ISDN and DSL Cable modems and leased lines T3 lines Synchronous Optical (SONET) Multichannel Multipoint Distribution Service (MMDS) Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 26 Convergence: Is It a Phone or a Computer? Digitization is the process of transforming data into a digital form. Convergence means two things in IT: The blending of multiple industries such as computers, consumer electronics, and telecommunications The blending of products such as personal computers and telephones Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 27 9

10 Convergence: Is It a Phone or a Computer? Cellular telephones, originally analog devices, are digital devices that use radio signals to transmit voice, image, text, and video data. Cells are the limited geographic areas through which signals are transmitted. Copyright 2009 Pearson Education, Inc. Publishing as Prentice Hall 28 Convergence: Is It a Phone or a Computer? Each cellular network includes multiple mobile switching centers (MSCs) that control communication within a set of cells. Copyright 2009 Pearson Education, Inc.
