Your Name: NETW410, Professor’s Name: Christine Adams Current Date: 03/23/2014 Lab 3: Designing the Infrastructure for the Network Lab Report 1. Draw a diagram of the new network. (10 points) 2. Will the current horizontal cabling suffice for the new network? If it will not, what type of cable should be used for the horizontal cabling?
Horizontal Cable - A type of inside cable designed for horizontal use in non-plenum areas. While horizontal cable must be fire retardant, the National Electrical Code (NEC) specifications are not as demanding as those governing the use of plenum cable or riser cable. Backbone Cable - is the inter-building and intra-building cable connections in structured cabling between entrance facilities, equipment rooms and telecommunications closets. Patch Cords - is an electrical or optical cable used to connect ("patch-in") one electronic or optical device to another for signal routing. Connectors - a pointer or link between two data structures Conduit - a tube or trough for protecting electric wiring Racks - framework, typically with rails, bars, hooks, or pegs, for holding or storing things.
Continuity Tester - is an item of electrical test equipment used to determine if an electrical path can be established between two points; that is if an electrical circuit can be made. 13. Category 5e/6 Cable - is a twisted pair cable for carrying signals/ is a standardized cable for Gigabit Ethernet and other network physical layers that is backward compatible with the
The backfill material needs to be compacted in lifts of loose depth that does not exceeding 8 inches and compacted to at least 95% of Standard Proctor Density at optimum moisture content, +/- two percentage points, as determined by ASTM D698 or provide the City with suitable advanced technology compaction testing methods, as approved by the Director 7. Is the company we hire to do the work required to be registered in any way? Yes, the company must be certified to work in public rights-of- way. 8. What is a right-of-way?
The scientist has a double slit of known separation. Describe the measurements that need to be taken and explain how they are used to find the wavelength of the light. Discuss any necessary safety precautions and how you would arrange the apparatus to improve accuracy. Measurements * w measured with vernier calliper * D measured with a meter rule Finding the wavelength * Use λ=wsD to obtain value for λ Accuracy * Several fringe spaces measured * Centres of fringes used * Five or more fringes measured * Large value for D * D greater or equal to 2m * Dark room * Repeat measurements Safety * Avoid shing laser at a person * Laser safety goggles * Avoid reflections * Warning sign or light Figure 4 shows a stationary wave on a string. The string is tied onto a thin metal bar at A and fixed at B.
The first step is to examine the issues using the utilitarian ethics framework. Act Utilitarianism The utilitarian ethical issue in the case centers on what action by the transistor company will result in the greatest good for the greatest number. The issue can be analyzed using act utilitarianism or rule utilitarianism. Using act utilitarianism, the issue is measured solely by asking if the one particular act does the most good for the most people (Kay, 1997). If the company sells transistors to the pacemaker company, they risk litigation (Shanks, 1996).
5.1.1 802.1 standard is basically that it handles the architecture, security, management and internetworking of LAN, MAN, WAN standardized by IEEE 802. 5.1.2 What 802.3 standard originally defined PoE functionality? The IEEE 802.3af standard When was the standard enhanced, and what was the new standard name given for the enhancement? It was changed in 2009 and it was called IEEE 802.3at 5.1.3 Ethernet Standards Standard | Speed | Segment Length | Cable | 10Base5 | 10Mbps | 500m | Rg-8 or RG-11 Coaxial | 10Base2 | 10Mbps | 185m | RG-58 A/U or RG-58 C/U Coaxial | 10Base-T | 10Mbps | 100m | Cat 3 or better UTP | 100Base-T | 100Mbps | 100m | Cat 5 UTP or STP | 100Base-TX | 100Mbps | 100m | Cat 5 UTP or STP | 100Base-FX | 100Mbps | 2km | 2-pair 850 nm Multimode optic fibers | 1000Base-T | 1Gbps | 100m | 4-pair, Cat 5 or Cat 5e | 1000Base-SX | 1Gbps | 550m (multimode) | 2-pair fiber optic | 5.1.4 What does the numeric prefix before BASE the Ethernet standards? It denotes its maximum data transmission rate What does the inclusion of the postfix of –T imply?
breaking long messages into several smaller messages The primary reason for networking standards is to: ensure that hardware and software produced by different vendors can work together ___________ refers to the spreading of the signal that different parts of the signal arrive at different times at the destination. dispersion ______________ refers to the time it takes for a signal to travel from sender to recipient (highly exaggerated with satellite transmission). Propagation delay A coding scheme that uses 10 bits to represent each character is capable of representing _________ different characters. 1024 Which type of digital signaling would experience fewer errors because it has more distinct signals? bipolar When sending four bits at a time using frequency modulation, the number of different frequency levels that would be needed would be _______.
And the cables leading to the negative terminals are black. If you are still unsure, the positive terminal on the battery will be marked with a “+” and the negative terminal with an “-“. Next, after you have completed the steps above you will need to retrieve the jumper cables. Your jumper cables should have a red (positive) and black (negative) cable with a clamp at each end of the cables to connect to your battery terminals. Separate the jumper cables making sure the clamps do not touch; it could cause a short circuit.
kk TRUE/FALSE The following are possible True/False questions for tests. The statement is given and the answer is provided in square brackets. The level of difficulty (easy, moderate, or difficult) and the page(s) relevant to the topic are also furnished. 1. A traditional network design approach follows a structured systems analysis and design process similar to that used in building applications.
