    Multiplexing and Switching Price 2.99  |  2.99 Rewards Points

    Multiplexing is a process in which multiple data channels are combined into a single data or physical channel at the source. Multiplexing can be implemented at any of the OSI layers.Conversely, de-multiplexing is the process of separating multiplexed data channels at the destination. One example of multiplexing is when data from multiple applications are multiplexed into a single lower-layer data packet.

    Transmission Media Price 2.99  |  2.99 Rewards Points

    In this present chapter, we learn the Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANS. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network’s topology, protocol, and size. Understanding the characteristics of different types of cable and how they relate to other aspects of a network is necessary for the development of a successful network.

    Telecommunication Price 2.99  |  2.99 Rewards Points

    Telecommunication is the technique of transmitting a message, from one point or place to another with the typical additional attribute of being bi-directional. In practice it also recognizes that something may be lost in the process; hence the term ‘telecommunication’ covers all forms of distance communication, including radio, telegraphy, television, telephony data communication and computer networking. The elements of a telecommunication system are a transmitter, a medium (line) and possibly a channel imposed upon the medium, and receiver.

    Cable Television Price 2.99  |  2.99 Rewards Points

    The first foray into cable television appears to have taken place simultaneously in both Pennsylvania and Oregon in the late 1940s and early 1950s. With the advent of satellite broadcasts to cable systems in the 1970s, cable operators were able to provide more channels than were available over the traditional airwaves. The cable industry is less than 50 years old, and yet with such a large market penetration, is already reasonably mature. In searching for growth opportunities, the much ballyhooed National Information Infrastructure (NII) or “information superhighway” provides an opening for cable television to build upon its extensive architecture and experience to deliver the necessary features for the upcoming information age.

    Routing Basics Price 2.99  |  2.99 Rewards Points

    Routers operate on layer 3 of the Open System Interconnection Reference Model, usually referred to as the OSI Model. Protocols are the language that routers use when speaking to each other. All routers operate on layer 3 of the OSI model and are capable of using multiple protocols such as RIP, IGRP/EIGRP, OSPF and BGP. Each of these protocols have advantages and disadvantages. Each protocol also has an ideal use, whether it is a small or large network.
  • Chapter 27

    Flow Control Basics Price 2.99  |  2.99 Rewards Points

    Flow control is a function that prevents network congestion by ensuring that transmitting devices do not overwhelm receiving devices with data. A high-speed computer, for example, may generate traffic faster than the network can transfer it or faster than the destination device can receive and process it. The three commonly used methods for handling network congestion are buffering, transmitting source-quench messages, and windowing.

  • Chapter 29

    Transport Layer Protocols Price 2.99  |  2.99 Rewards Points

    In order for the data to be sent across the network, the file must be broken up into usable small data segments (typically 512 - 18K bytes). The Transport layer breaks up the file into segments for transport to the network and combines incoming segments into a contiguous file. The transport layer does this logically not physically, it is done in software as opposed to hardware. The transport layer provides error checking at the segment level (frame control sequence). This checks that the datagrams are in the correct order and the Transport layer will correct out of order datagrams. The Transport layer guarantees an error-free host to host connection, it is not concerned with the path between machines.

    Application Layer Price 2.99  |  2.99 Rewards Points

    The application layer provides to an application process the ability to communicate with another application process, to exchange information and interoperate in the accomplishment of a particular goal. Of all the seven layers of the structure of Network resources, only the application layer interacts directly with the other components of an application process. It is the only way available for an application to gain access to the resources needed for communication, and the only way for an application to determine the characteristics of that communication.
