It denotes its maximum data transmission rate What does the inclusion of the postfix of –T imply? A reference to the twisted pair cable needed for this standard. Lab 5.1 Review 1. What would the maximum speed of traffic be from a node in network A to a node in network B? 10 Mbps 2.
The battery’s positive lead pushes current away from that lead, and c. The circuit creates a direct current. 2. A PC NIC and a switch port create one electrical circuit to use when sending data. The sender creates a (maximum) 1-volt electrical signal with a frequency of 1000 hertz. Which of the following facts are also true?
What devices would operate at the access layer? Draw a diagram of these devices at the access layer. Label all of the devices. (10 points) Yes, this network does require an access layer for the users to connect to the network. Devices in this layer are the lower end switches and wireless access points.
Question 2 (Objective 3f) – You are using the break-even analysis to decide whether to make or buy a small metal part used in your product. The variable costs are $10 to buy and $5 to make. The fixed costs are $2000 to buy and $22,000 to make. Therefore, you should: a) Buy the part if volumes are expected to be greater than 4000 b) Buy the part if volumes are expected to be greater than 3000 c) Make the part if volumes are expected to be greater than 4000 d) Make the part if volumes are expected to be greater than 3000 Question 3 (Objective 3a) - The goals of a purchasing organization include: a) Reducing total cost b) Ensuring raw materials are on hand when they are needed c) Reducing price only d) All the above e) A and B only Question 4 (Objective 3b) - A buyer received a materials requisition for a new part. What should the buyer do next?
C. two PCs, with one cabled to a router Ethernet port with a crossover cable and the other PC cabled to another router Ethernet port with a crossover cable. 7. A. hubs create a single electrical bus to which all devices connect, causing the devices to share the bandwidth. C. hubs allow collisions to occur when two attached devices send data at the same time. 8.
The __________________ tool provides a central access point for all of the network controls and connections on a computer running Windows 7. Network and Sharing Center 3. A device that connects one network to another is called a __________________. router 4. The most common method for illustrating the operations of a networking stack is the __________________, which consists of __________________ layers.
Classes C is for small networks with few hosts. These addresses have the first three high-order bits set to 110, because Class C addresses use the first three octets for the network ID and the last octet for the host ID. Class D is reserved for IP multicast addresses. The first four high-order bits are set to 1110. The remaining 28 bits are used for individual IP multicast addresses (Shimonski & Alpern, 2009).
William H. NT1310 – Mrs. Goodbar 4/2/14 Unit 3 Assignment 1: Network Topology Paper Hierarchal Star each of these devices comes with its own cable that links to a central hub, or sometimes a switch, multipoint repeater, or even what is called a MAU (Multistation Access Unit). Data passes via the hub to reach other devices on the network, one of the most common networks are Star Networks. Star Network is one of the easiest network setups, a downside is that if your hub goes down the entire network goes down. A bus topology is a type of network setup where each computer and network device is connected to a single cable or backbone. One way to think about a bus topology is that the line connected to all of the devices or nodes in the network
To calculate the separate hurdle rates the cost of equity for each segment must be determined first. Betas used to calculate cost of equity are the industry averages as there are no separate betas listed for each segment. If separate betas were given they may slightly differ from the industry averages used. Exhibit 1 shows the cost of equity by segment. Telecommunications has a cost of equity of 10.34 percent while Products and Systems is 12.1 percent.
5. What type of DSL is capable of speeds of up to 100Mbit/s? VDSL (Very High Bitrate DSL) speeds range from 4Mbit/s to 100Mbit/s Circuit Switching and Packet Switching 1. Which technology, circuit or packet switching, is most like the technology utilized by POTS? POTS (plain old telephone service) utilizes circuit switching technology.
