Section 6.1, Question 3:
Unmanaged switches used to communicate to another device. Ethernet devices allow to talking to other devices like computer or printer. these are not allowed any changes to the configuration. Most of the time used for small networks or connect to the large network to the small network. Coming to the managed switch. It is provided all the features of unmanaged switch Not only that it has some extra features. We will configure, monitor LAN and manage a network. Easily track how the data travel over the network and easily find who access it. We can easily manage protocols and know who call the SNMP and know who exchange the information between network devices and tells the status of the device and health of the network,

In that case, configure the port vale other than auto. For manual configure port seed is set to 10 or 100 Mbps the switch allows to configure the duplex mode. We cannot change the duplex mode of auto-negotiation ports. If it is a set the port speed varies to trigger on to auto on a 10 or 100 Mbps Ethernet port.
Section 6.4 Question1:
• VLANs provide high network security. Sniffing the network is difficult. We can control whenever resource to allow.
• Large to small VLANs reduce the broadcast traffic and sent to the data to required VLAN.
• Basically, routers costlier than switches. VLANs is cost-effective than creating a new routed network with routers
• VLANs tell which network is connected and very transparent on the physical topology
Section 6.5 Question 1
Trunking is basically carried multiple signals simultaneously and give them access to network points. It has many cables; wires and it increases the bandwidth of the network. It multiplexed the physical cables. A trunk connects to the switch nodes. Exchange information from central office to branches. In the data network, we have two methods. first thing trunk transfer data from local area network to virtual area networks. Second trunk bod multi-physical link to single. this trunking. Trunk port defined in IEEE standards.
Section 6.6 Question
Even though it does not look very important part of the driving pile, the new cushion pad of Curled Metal Incorporated (CMI) can provide remarkably advanced performance in all its aspects. Its durability allows the equipment to finish the job which required 20 sets of conventional pads with only one set of CMI pads. It also allows the pile to drive much faster with less weight and less heated. In order to set an appropriate price of the product, I have considered the minimum price that is calculated from CMI’s cost, and the maximum price that is calculated from customer’s willingness to pay (WTP).
From Fig 3, it is possible to note that occurs a decrease in the maximum annual demand on the feeder when DGs are connected to the electrical network, except when it is only inserted WGs on the network (the influence in this scenario can be neglected). Table III shows the annual maximum demand of the feeder 1 and its variation in relation to Case
In the first part of this analysis, you will be examining whether “certain death” warning effectively changed evacuation decisions of those households inside the risk area of Houston-Galveston Study Area who originally refuse to evacuate. In addition, you also need to specify the differences between a McNemar test and a Chi-square test which are two similar cross-tabulation tests. The variables for your analysis in this part are evacuation intention and evacuation decision. You are required to examine whether there is a significant difference between the pair of those respondents who originally refused to evacuate but actually left and those who originally expected to evacuate but actually stayed. You are also asked to run both McNemar test
According to (Burke, 2004),A switch is a multiport bridge. When a switch receives a frame (A data packet with address and other protocol information embedded), it amplifies the signal, looks at the MAC address to determine which port should retransmit the frame to get it to the intended network device and sends it to that port. The switch can be configured to disconnect any attached device, to discard frames intended for an attached device, to send frames with a specific hardware address to another hardware address instead and to copy a frame to a mirror port which can send it to an attached traffic monitor.

CM emailed Andrea Orlando (Daytop Program Coordinator) a copy of Dre’quan’s (youth) updated biopsychosocial (BPS) and court order. Ms. Orlando reported the clinical director will review youth’s documents and will determine admission date. Ms. Orlando will continue to keep CM updated regarding youth’s status. CM provided CM’s contact information.
In order to mitigate these risks, it is imperative network switches are hardened. Additional controls may include ARP inspection, disabling unused ports and enforcing effective security on VLAN’s to prevent VLAN hopping.
at a time,they are commonly connected to a LAN and run multiuser operating system.The resources which has to be managed
HomePort has a service-oriented architecture and uses defined protocols and interfaces. In addition, it has the following architectural equirements:
6. Why is Ethernet technology more appealing to users than the rest of the LAN technologies?
When setting up a LAN the architecture that you decide to choose is important. There are several factors that are decided when choosing said architecture, some of these being network speeds, types of cables, and access control mechanisms like collision detection (Team, 2011). The most common on in today’s LANs is Ethernet. These can be either wireless, wired, or a hybrid of both.
All main networking, router, switches and servers will be in a closet that is only accessible to the networking team, this way it’s not
IT IS important to have logical and physical network design diagrams. These diagrams help us in understanding of the entire network with its functionalities.
Broadcast Control – In a pure Layer-2 environment, broadcasts are received by every host on the switched network. In contrast, each VLAN belongs to its own broadcast domain (or IP subnet); thus broadcast traffic from one VLAN will never reach another VLAN.
Switched virtual circuits also can provide "bandwidth-on-demand" meaning that when the line is at its peak carrying information more bandwidth can be made available. Also switched virtual circuits allow charges for connection to be made only for what the customer uses, unlike leased lines where you have to pay a flat rate (828-829).
