NT 1310 NETWORK TOPOLOGY PAPER: KENDAL JEFFERSON Network topology refers to layout of a network and how different nodes in a network are connected to each other and how they communicate. Mesh Topology: in a mesh network‚ devices are connected with many redundant interconnections between network nodes‚ in a true mesh topology every node has a connection to every other node in the network. There are two types of mesh topologies: Full mesh occurs when every node has a circuit connection it to every

between walls‚ under structural floors‚ and above drop ceilings when used to circulate and otherwise handle air in a building. Riser: A space for indoor cables that allow cables to pass between floors‚ normally a vertical shaft or space. RIP cord: A length of string built into optical fiber cables that is pulled to split the outer jacket of the cable without using a blade Core: Anything that is found within the sheath‚ usually just the twisted pairs. Commonly referred to incorrectly as the core

NT 1310 PHYSICAL NETWORKING UNIT 7 DEFINITIONS KENDAL JEFFERSON 1. 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. 2. WAVEGUIDES: A structure that guides electromagnetic waves along their length. The core fiber in an optical-fiber cable is an optical waveguide. 3. FTTH: :

Ghattas The differences between LED and Laser Transmitters LED LED (Light-Emitting Diode) is a two-lead semiconductor light source. It resembles a basic p-n junction diode (is a boundary or interface between two types of semiconductor material‚ p-type and n-type‚ inside a single crystal of semiconductor.‚ which emits light when activated.

(2) A system‚ the transmission method of which is supported by telecommunications cabling‚ such as 100Base-TX Ethernet‚ or digital voice. (Oliviero & Woodward‚ 2011) Unshielded Twisted-Pair: (1) A pair of copper wires twisted together with no electromagnetic shielding around them. (2) A cable containing multiple pairs of UTP wire. Each wire pair is twisted many times per foot

Telecommunications Network Components: a. Cellular Telephones: I. Voice: Voice calls are transmitted wirelessly. The call is transmitted over radio waves to a cellular tower which then routes the call through the service provider which is then sent to the party on the other end. II. Data: Commonly called mobile internet‚ data is sent over radio waves in 3G or 4G connections. The Data is streamed over the phone similar to the way the internet connects to a computer. b. Telephone Network Topology: I. Demarcation

The network Kudler is using is called a bus topology that uses a common backbone to connect all devices. If one of the systems on the network wants communicates to another system‚ it broadcast a message

If I choose to design the new building with a wired network the main benefit is there would be a low chance on interception. Choosing a wired network will also have a lower risk of security issues; reliability and speed are primary benefits as well when using physical connections in a wired network. The basis of the new building will relay on loads of data to be moveable that is why a wired network allows the control. Wired LANs provide superior performance. A wired network is also more cost effective

Executive SummaryThe objective at hand was to build a network from the ground up. This was accomplished by breaking down all of the sections and building upon all previous assignments. This was a good course as I learned a lot about all of the different sections of building a network. The pros are now I know how to build a network on the design side from the ground up. I learned quite a bit about using a lot of the technologies associated with networking and it allowed me to learn quite a few new
