...They would also like to include an Electronic Medical Record system such as AllScripts, EPIC, or NexGen that will need to be accessible to all employees and doctors. This will be a new satellite office for an existing office that is ten miles away. What we plan to cover in this paper will be the specifications it will take to get this office’s network up, running, and able to support the equipment, software, and databases they are trying to implement, while also giving them the ability to communicate with their Main office. We will also have to ensure that what we create is very secure, and follows all HIPPA requirements for the network and data storage. We will go over the networks design including topology, Network Interface Cards (NICs), network operating system (NOS), cabling, where will the companies devices be located (servers, hubs or switches, printers, firewalls and routers, modems etc.), and how many users will they have. We will also discuss security measures such as, backup processes, and power it will take to sustain this network and its devices. For security we will discuss Virus protection, user passwords, firewalls, data encryption, and what physical security measures may need to be used. When designing the backup plan we will discuss capacity, how it will be done, can it sustain growth, frequency, and how and where it will be stored (on campus, off campus, or both). And lastly we will discuss the source of power and ventilation it will take to sustain the company’s...

...IT130 Introduction to Networking Final Exam Study Guide These are the facts from which your exam questions will be drawn. If you know these facts, you will do well on the exam. All models are a simplified representation of the real thing, having at least all the major functions of the real item. What constitutes a major rather than a minor function is open to opinion. Most networks use a cable known in the industry as an unshielded twisted pair (UTP), usually containing four pairs of wires that can transmit and receive data. Cabling and hubs operate at the Layer 1 (Physical) layer of the OSI model. In the command window, when the utility to show the IP address and other NIC information is run, the MAC address is listed as the Physical address in the third section of the information. All NICs on the same network must use the same frame type, or they will not be able to comunicate with other NICs. 67.21.321.4 is not a valid IP address, as the third octet (321) is greater than 255. IP uses a rather unique dotted decimal notation (sometimes referred to as a dotted-octet numbering system) based on four 8-bit numbers. Each 8-bit number ranges from 0-255, and the four numbers are separated by periods. The TCP/IP model has four layers (Link, Internet, Transport, Application), unlike the OSI model which has seven layers. Transmission Control Protocol (TCP) is a connection-oriented protocol, meaning, it requires verification that a good connection has been established before transmission...

...1. Application: Application is the term used within the Information Technology industry to reference software. The software can be for the end user which is known as the application software or it can be a Systems application software. 2. Unshielded twisted-pair: UTP, is also known as Category 5, and or Category 6. Consisting of 2 twisted pair of copper wire. UTP is the main type of cable used in LAN topography. 3. Shielded Twisted-Pair: Is similar to UTP, the main difference is that it is has an additional layer of shielding, this shield helps in preventing EMI, and other interference. STP is great application when a cable is being applied near power lines, metal pipes and is not in protected by plenum or conduit. 4. Fiber Optic Cable: Is a great long distance cable. There is Single mode, in which laser is transmitted and there is multimode, in which LED is transmitted. Both fiber cables are use to cover great distances up to allow data to traverse the fiber optic cable near the speed of light. 5. Dark Fiber is fiber optic cable is this idle and is not currently being used. 6. Coaxial Cable is an older cable that has a grounding copper core that is surrounded by a plastic protective insulating sheath, and then a protective grounding shield, and then there is the black outer protective plastic covering. 7.

...Plenum The air-handling space between the walls, under structural floors, and above drop ceilings when used to circulate and otherwise handle air in a building. Plenum-grade cable can be run through these spaces if local building codes permit it. Decibel (dB) A standard unit used to express a relative measurement of signal strength or to express gain or loss in optical or electrical power. A unit of measure of signal strength, usually the relation between a received signal and a standard signal source. The decibel scale is a logarithmic scale, expressed as the logarithmic ratio of the strength of a received signal to the strength of the originally transmitted signal. For example, every 3dB equals 50 percent of signal strength, so therefore a 6dB loss equals a loss of 75 percent of total signal strength. Signal Attenuation A reduction of signal strength during transmission, such as when sending data collected through automated monitoring. Attenuation is represented in decibels (dB), which is ten times the logarithm of the signal power at a particular input divided by the signal power at an output of a specified medium. Crosstalk The coupling or transfer of unwanted signals from one pair within a cable to another pair. Crosstalk can be measured at the same (near) end or far end with respect to the signal source. Crosstalk is considered noise or interference and is expressed in decibels. Federal Communications Commission - FCC An independent U.S. government regulatory...

...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...

...a few recognised courses on structured cabling systems which offer some hands-on experience, or you could take one of the many courses offered by the manufacturers of cabling components. Obviously the manufacturers try to sell their own products, but their courses are usually cheaper and they can still provide some of the basic cabling skills. | There are also lots of books on the subject of cabling and a selection of these can be found in the Network Cabling Help shop, my personal favourite is The Cabling Handbook 2nd Edition by John Vacca. It has over 1300 pages covering all aspects of network cabling and includes chapters on The Standards, Network Design, Wireless Communications, Fibre and Home Wiring. If you don't want to invest any money on training until you are seeing some financial results, then you can gain valuable experience by actually doing some work for an existing cabling company. Here are some basic questions you may be asking yourself if you have never installed a structured cabling system before. What are 'The standards' ? There are three main cabling standards: * EIA/TIA 568A - This is the American standard and was the first to be published (1991). * ISO/IEC 11801 - The International standard for structured cabling systems. * CENELEC EN 50173 - The European cabling standard. The reason for having a 'Standard' is to define a method of connecting all types of vendors voice and data equipment, over a cabling system that uses a common media...
