  • The implementation of wireless connectivity is predicated upon the definition of so-called wireless standards, of which GSM, DECT, CDPD, GPRS, and CDMA are examples [7, 8]. Each of these standards embodies the precise set of parameters that dictate the architecture and software design of wireless systems operating under the standard to effect intelligible communicationwith other systems also operating within the standard.

  • 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. ...

  • When in 1899 I published the "Bristol Royal Mail," I scarcely supposed that it would be practicable to gather further historical facts of local interest sufficient to admit of the compilation of a companion book to that work. Such, however, has been the case, and much additional information has been procured as regards the Mail Services of the District. Perhaps, after all, that is not surprising as Bristol is a very ancient city, and was once the second place of importance in the kingdom, with necessary constant mail communication with London, the seat of Government. .

  • One of the major functions of the physical layer is to move data in the form of electromagnetic signals across a transmission medium. Whether you are collecting numerical statistics from another computer, sending animated pictures from a design workstation, or causing a bell to ring at a distant control center, you are working with the transmission of data across network connections. Chapter 3 discusses the relationship between data, which are created by a device, and electromagnetic signals, which are transmitted over a medium.

  • LANs do not normally operate in isolation. They are connected to one another or to the Internet. To connect LANs, or segments ofLANs, we use connecting devices. Connecting devices can operate in different layers of the Internet model. In this chapter, we discuss only those that operate in the physical and data link layers.

  • Chapter 23 - Process-to-process delivery: UDP, TCP, and SCTP. Chapter 23 discusses three transport layer protocols in the Internet: UDP, TCP, and SCTP. The first, User Datagram Protocol (UDP), is a connectionless, unreliable protocol that is used for its efficiency. The second, Transmission Control Protocol (TCP), is a connection-oriented, reliable protocol that is a good choice for data transfer. The third, Stream Control Transport Protocol (SCTP) is a new transport-layer protocol designed for multimedia applications.

  • What Is Accent? Accent is a combination of three main components: intonation (speech music), liaisons (word connections), and pronunciation (the spoken sounds of vowels, consonants, and combinations). As you go along, you'll notice that you're being asked to look at accent in a different way. You'll also realize that the grammar you studied before and this accent you're studying now are completely different. Part of the difference is that grammar and vocabulary are systematic and structured— the letter of the language.
