...Chapter 1 Basic Networking Chapter 1 Basic Networking: Data communication is the transfer of data from one device to another via some form of transmission medium. A data communications system must transmit data to the correct destination in an accurate and timely manner. The five components that make up a data communications system are the message, sender, receiver, medium, and protocol. Text, numbers, images, audio, and video are different forms of information. Data flow between two devices can occur in one of three ways: simplex, halfduplex, or full-duplex. A network is a set of communication devices connected by media links. In a point-to-point connection, two and only two devices are connected by a dedicated link. In a multipoint connection, three or more devices share a link. Topology refers to the physical or logical arrangement of a network. Devices may be arranged in a mesh, star, bus, or ring topology. A network can be categorized as a local area network (LAN), a metropolitan-area network (MAN), or a wide area network (WAN). A LAN is a data communication system within a building, plant, or campus, or between nearby buildings. A MAN is a data communication system covering an area the size of a town or city. A WAN is a data communication system spanning states, countries, or the whole world. An internet is a network of networks. The Internet is a collection of many separate networks. TCP/IP is the protocol suite for the Internet...

And to our most beloved parents, guardians which God used in providing the financial resources for us. We say a very big thank you to them all and pray that God bless us all. THANKS CHAPTER ONE INTRODUCTION DEFINITIONS OF SOME TERMS A DIGITAL SYSTEM is a data technology that uses discrete (discontinuous) values. By contrast, non-digital (or analog) systems represent information using a continuous function. Although digital representations are discrete, the information represented can be either discrete, such as numbers and letters or continuous, such as sounds, images, and other measurements. The word digital comes from the same source as the words digit and digitus (the Latin word for finger), as fingers are used for discrete counting. It is most commonly used in computing and electronics, especially where real-world information is converted to binary numeric form as in digital audio and digital photography. DIGITAL TRANSMISSION SYSTEM is a transmission system in which (a)...

...layered approach, where a communication subsystem is broken down into seven layers, each one of which performs a well-defined function. Additionally it is important to understand the purpose of the OSI model in the overall networking architecture especially as it relates to the TCP/IP (Transmission Control Protocol/Internet Protocol) Architecture, which also consists of layers each playing a particular role in the networking design. Generally speaking, the network protocol layer, which is similar to the data and network layer of the OSI model includes the protocols that allow clients and applications to send data over the network. This includes TCP/IP, NWLink (IPX/SPX), NetBEUI, Infrared Data Association (IrDA). However, the purpose of this document is to focus on the relationships between the OSI model and the TCP/IP architectures, and how they may interact together. Finally, as demonstration of this relationship a visual diagram has been provided to depicts how the TCP/IP layers correspond to the OSI model and layers. To begin with, it is important to understand the seven different layers of OSI Model and the functions they provide in the networking architecture. Below is a list of each OSI layer, their description and the function they serve in processing data over the network. • The application layer is the end-user process requests with applications and communication, all application specific. The function of an...

...What does the Shannon capacity have to do with communications? The Shannon capacity has to determine the theoretical highest data rate for a noisy channel through the following formula: Capacity=bandwidth×log_2 (1+SNR)[4] 3.8.3 Problems: P3-7. What is the bit rate for each of the following signals? a. A signal in which 1 bit lasts 0.001 s Basically, bit rate is donated as r_b and we can found it by using the following formula: r_b=n/T Whereas n measured in bits, and T measured in second. [5] So, in such a case: r_b=1/0.001=1000bps b. A signal in which 1 bit lasts 2 ms First, we need to convert 2 ms to second. 2 ms=2×〖10〗^(-3)=0.002 s r_b=1/0.002=500bps c. A signal in which 10 bits last 20...

...Chapter 3: Transmission Basics and networking media Transmission Basics Transmit: to issue signals along a network medium such as a cable. Transmission: Refers to either the process of transmitting or the progress of signals after they have been transmitted. * Analog and Digital Signaling: * On a data network, information can be transmitted via one of two signaling methods, analog or digital. * Voltage: the strength of an electrical signal * Analog: * One benefit to analog signals is that, because they are more variable than digital signals, they can convey greater subtleties with less energy. * One drawback to analog signals is that their voltage is varied and imprecise. Thus, analog transmission is more susceptible to transmission flaws such as noise, or any type of interference that may degrade a signal, than digital signals. * Digital: Composed of pulses of precise, positive voltages and zero voltages. A pulse of positive voltage represents a 1, a pulse of zero voltage represents a 0. * Continuous * Amplitude: Waves amplitude is a measure of its strength at any given point in time. The amplitude is the height of the wave at any point in time. * for example, the wave has an amplitude of 5 volts at .25 seconds, an amplitude of 0 volts at .5 seconds, and an amplitude of -5 volts at .75 seconds. * Frequency: the number of times that a waves amplitude cycles from its starting point, through its highest amplitude and its...
