A PC NIC and a switch port create one electrical circuit to use when sending data. 1- volt electrical signal with a frequency of 1000 hertz. Which of the following facts are also true? (Choose two answers) 3. Which of the following tasks is a function done by the transmitter?
1. You have created a simple electrical circuit with a battery, wires, and a light bulb. Which of the following is true about this circuit? (choose two answers). a.
Assuming that 802.11n uses the narrower 20-MHz channel and a single stream, which of the following answers matches a particular standard to its maximum bit rate? a. 802.11g: 54 Mbps 3. An enterprise campus LAN uses wired UTP Ethernet and wireless 802.11 LANs at the edge of the LAN. A network engineer uses a WLAN testing tool to view the frames moving through the WLAN, and he notes the speeds of the various frames in a single WLAN that uses a single access point.
11. Cable Toner12. Continuity Tester- 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 standardized cable for Gigabit Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards 14. Binder Groups- Cable pairs are typically arranged under the cable sheath in binder groups 15.
NT1210 LAB 4.1 Exercise 4.1.1: Why are standards so important for NICs, connectors, and media? Use your textbook and Internet research to justify your answer. Standards are put in place to make everything work together error free. Because Stability, Consistency, Minimization of packet errors. Exercise 4.1.2: The voltage for registering a bit of 1 on Ethernet can be as low as 2.5 volts or even 1 volt.
Question 46: Consider the network diagram presented below, let’s assume that both switches are capable of auto negotiating Ethernet speeds of 10, 100, and 1000 Mbps. Let’s also assume the switches do not support MDIX. Refer to the network diagram. Identify what the Layer 1 issue would be in this topology. Question 47: What is the administrative distance of Open Shortest Path First (OSFP) routing protocol?
The literal distance depends on conditions in each wireless LAN. The two types of LANs should have little or no impact on the distances allowed by each. 2. IEEE 802.11 standards define a maximum speed for an individual transmission, with some variables that affect 802.11n speeds. Assuming that 802.11n uses the narrower 20-MHz channel and a single stream, which of the following answers matches a particular standard to its maximum bit rate?
Preferred Optical fiber to support 10Gbps is a single mode for long distance and multimode for short distance. 1. What Ethernet network application ports/modules should you use for horizontal links? -100Mbps for the horizontal, workgroups should have an uplink of 1Gbps 2. What are your horizontal cabling options?
Master It – The customer wants to ensure capability to operate 10Gbase-T What cable would you recommend to offer the best shielding performance? I would recommend the screened shielded twisted pair (f/FTP and S/FTP) Determine the uses of pleum-and-riser-rate cabling. Plenum cable – Cable whose flammable and smoke characteristics allow it to be routed in in air handling space between the wall, under structured floors, and above drop ceilings, without being enclosed in a concuit. Riser Cable- A type of cable to be used in vertical building shafts Such as telecommunications and utility
To be able to show all 16 possible numbers 0-15 you can change the circuit so that the most significant bit (the eights place) is shown by an LED and the rest of the number is displayed on the MAN72, this would then be a successful binary to octal number system conversion circuit. Lab 4 – Logic Gates Materials: - 7400 quad 2-input NAND gate - 7402 quad 2-input NOR gate - Two 1.0 kΩ resistor Purpose: The purpose of this exercise was to set up a simple NAND or not and gate and a NOR, or not or, gate. Once set up, using one of the resistors to ground for a logic of one and a simple jump to ground for a logic of zero, the goal was to test the truth tables for these two gates. Procedure: The setup was incredibly simple, we simply set up and VCC’d the ICs and then began to test. The trouble came when our results were not matching the anticipated theoretical results.
