To get started the LAN would be the main configuration for connecting the computers on each floor with star typology. Star topology will connect all nodes individually to a central connection point also known as the switch. A pro with this configuration if a cable fails only one node will be brought down and the rest will continue running. In addition, we can use twisted pair for the wire used to simply to cancel out electromagnetic interface from external sources since there will be multiple computers next to each other. The copper wire will lead to a switch connecting the devices together on the same network. This will also lead to the building backbone network. Also, known as the distribution layer, because it will be distributing network traffic to and from the LANs. Now those that we have the wire network it’s also recommended to have a wireless network in each building because many students will be using their own devices. We can simply set up 802.11 (WiFi) since we already have a wire network the campus should get by to support the users.
Furthermore, the switches on each floor would connect to the main switch on the first floor of each

Which is also known as the core layer campus backbone network. Essentially everyone on campus will have internet connectivity and connect to any server or printer located in any of the other buildings. The reason behind this is the data center is the home of the database servers as well as mail servers. Any devices for example printers connected to the network users will be able to have access to them. If users needed to access the network from home or other features we can add VPN to the network. This will allow us to create a secure connection to the network over the internet. With this design the campus will have a much more reliable network to its
I. Site “Springfield” Device and STP Configurations Site Details and Challenges (Summary) This section will implement device hostnames (to correlate with the xACME educational topology labels), provide a sample configuration for the MOTD and login banner, and provide configuration steps for applying device passwords (encrypted) on the console port and VTY. This section will also review what the Spanning Tree Protocol (STP) does, its benefits, and provide a sample configuration for applying STP on the switches. Security methods that can be applied to the devices will be reviewed as well.
HOMEWORK ASSIGNMENT 1 PROF: TOM WILKES FALL 2015 AKHILA DAMERA 1. What is the purpose of an interrupt? Answer: An interrupt is a signal from software or hardware. It indicates the occurrence of an event.
Once, the current rating and voltage rating are chosen, one needs to look at the data sheet of the connector to check whether it meets the given specifications. In the datasheet, one should look at the test procedure used to arrive at the specifications and check whether it meets the test standard. Not everyone uses the same testing criteria, so ensure you understand how these specifications were derived. It should also be confirmed that the contact will support the conductor size that has been chosen. A non-compatible conductor could cause overheating issues, leading to premature connector failure.
I am going to explain the current methods and protocols we use in a LAN environment to provide a high level of redundancy, such as EtherChannel, FHRP (First Hop Redundancy Protocols) and STP (Spanning Tree protocols). I will briefly explain how the protocols work & then discusses the latest implementations of the protocol and the environment you would expect to see them working in. The STP is a protocol that prevents loops from occurring in a switched LAN environments when a device has multiple interconnected paths. The protocols works by sending BDPU messages across in the interconnected devices, detects the loop then removes it from the topology by shutting down the port.
Task 1 1.1) Design a networked system to meet the given specification. Your design must satisfy the user requirements and be scalable. [3.1] The design of the network system should include: cost, Bandwidth, system growth, applications, communications, and scalability of the system and selection of components. Introduction - Designing the Network In this design I will be listing and discussing, through the different and necessary designing stages, the various elements involved in designing a network that meets the system requirements given by the client.
1. Request: The industry of construction is an industry where a firm has to be precise and very accurate. This is why I will be requesting that the superiors in my company purchase a piece of software Chief Architect, and revert from using their current software Sketch-up. This task will require persuading because the owners of the company think that using open-source software like Sketch-up will be sufficient.
2.1 AWS Networking AWS provide a kind of networking services that also provide private network connections to the cloud, scalable DNS and tools to make logistically solitary networks. There are also have prevalent networking services comprise the Amazon Virtual Private Cloud (VPC) and Amazon Direct Connect. Amazon VPC generates a logically solitary set of Amazon EC2 for example which can be connected to current network using VPN connection. Amazon VPC generates a private cloud inside AWS, while deposition built-in security with security groups and network access control lists. When using Amazon EC2, VPC is free.
In order to access a UNIX system, and use it , you need to connect to the system. You can login: Locally Remotely Login Types In general, there are two ways: Command-line Login GUI Login Connecting Locally Connecting locally means, you are directly logging into the UNIX system. Network connectivity is not required.
Understanding networking is a fundamental part of configuring complex environments on the internet. This has implications when trying to communicate between servers efficiently, developing secure network policies, and keeping your nodes organized. Every location or device on a network must be addressable. This is simply a term that means that it can be reached by referencing its designation under a predefined system of addresses. In the normal TCP/IP model of network layering, this is handled on a few different layers, but usually, when we refer to an address on a network, we are talking about an IP address.
Sharing Internet Access: within a computer network learners are able to access the internet at once. Speed: Using a network is a faster way for sharing and transferring files. Without a network, files are shared by replicating them to a floppy disk. Cost: Networkable versions of many popular software programmes are available at significant savings compared to buying individual licensed copies. It also allows easier upgrading of the program.
When asked what a network is, I usually think about the internet or my phone’s network. It had never occurred to me to go further in depth on the subject. In order to fully understand what a network is we must look into what all networks have in common. All networks whether they are a broadcast, a computer, or a business network (the list goes on) all share common traits. There exists a hierarchy within each network and the more connections one has, the better.
1- The electromagnetic spectrum is the range of all type of EM radiation. It also describes the wavelength of light. EM radiation is the radiant energy that is released by a certain electromagnetic processes and a wavelength is the distance between successive crests of a wave. 2- The different between ionising and non-ionising radiation is that ionising radiation carries energy to ionize atoms and has more energy than non-ionising.
Encryption Security: Hard drive encryption: Without hard drive encryption if a hard drive becomes lost all the information on the hard drive would be viewable by plugging it into another computer. Particularly with a peer to peer network all the other computers on the network will be available if the hacker can access one. Wireless encryption: Wireless encryption is not as secure as a physical network, especially; if that wireless encryption is going to be the main way that strangers will be connecting to the network. All wireless protocols need to be at least WPA2 because of how many tools are out there and older models can be cracked.
Here are the some basic process and essential commands I would use that would help me determine and address network problems. 1. My initial process is to check if the computer is connected to the network by checking if the Ethernet cable is connected to it? Is the router turn on? Is it receiving signal form the ISP?
1. The operating system I am using is windows 7 and it allows me access Word, Excel, Access and PowerPoint. 2. A user interface is the way in which the user will interact with the computer system and all the apps that are available on the computers software. The components of a user interface is navigation mechanism, input mechanism, and output mechanism.
