  • For example, communicating between two PCs via a telephone line (connected between subscriber's home and local office, then between local offices, and finally between local office and another subscriber's home). The telephone line is an analog system. That means it can not be used for digital transmission. If we try to transmit digital signals over the analog system, our bit rate or bandwidth will be limited to a minimum. On a 4 kHz analog band limited system we can only transmit at a maximum rate of roughly 1 kHz. Because a 1 kHz digital signal needs a bandwidth of 5...

  • Parallel: In parallel transmission all bits in a single character are transmitted simultaneously. Data travels in parallel (simultaneously) within a PC over the data bus (bundle of data lines). Similarly we can transmit data between two PCs in parallel. That is all data lines (normally 8) from one PC are connected to the other PC. Parallel transmission is primarily limited to transmission of data within a computer, between computers and between a computer and a printer. It is fast compared to serial transmission but limited to shorter distances. ...

  • It is easy to think about online community from the technical point of view. Of course Internet access and the appropriate software are critical. But there are many more factors that influence the success of an online community. Most of them are non-technical, but often less apparent. Think of an iceberg. Only a small part shows above the water. In online communities: • the tools and technology are the top of the iceberg; and • the social/cultural, and organizational/environmental factors are the bigger, unseen piece “below the visible water line...

  • In this chapter, we show how the virtual-circuit approach can be used in wide-area networks. Two common WAN technologies use virtual-circuit switching. Frame Relay is a relatively high-speed protocol that can provide some services not available in other WAN technologies such as DSL, cable TV, and T lines. ATM, as a high-speed protocol, can be the superhighway of communication when it deploys physical layer carriers such as SONET.

  • Asymmetric Digtal Subscriber Line (ADSL) use is one of the general Digital Subscriber Line (xDSL) techniques. While it has been around in the laboratory for about ten years, this particular technique has since shifted to the special evaluation site to the beginnings of consumer access. By the time this book is available, some mass provision of ADSL to the general consumer market will be available.
