In which this can lead to downtime for the business and its users. Most companies rely on their network and cannot afford to have any downtime at all; therefore, it is necessary to have the correct topology to help make your business profitable. A bank or a major business depends on having a reliable network that will not have a significant amount of downtime that would affect their everyday business. For the second scenario XYZ Technology Consultants, I also think that Ethernet would be the better choice here. With the amount of floors, being occupied the reliability of using CAT 5, wireless, or Fiber Optic lines to ensure fast and reliable data transfer would seem to be necessary.
Once the network has been fixed, all of the computers on the network will be able to transfer and communicate information back and forth. That’s why a communication protocol is very important. Traffic analysis is defined as the process of gathering information from the features of communication traffic other than its contents, such as timing and size. Traffic analysis can be utilized on any type of network. When using traffic analysis, this process reveals the amount, type, origin and destination of the traffic flow on a network.
The amount of units that the data is sent in is called packets. Datagrams: Datagrams aren't very reliable because they work by themselves and also you aren't always guaranteed that your data will get to it's destination as a whole when you first sent it. This is were higher protocols come into play because they decide whether the data reaches it's destination. People who stream a lot such as, video, audio, voice use datagrams because it'll still be okay if a few are lost on the way. Addresses: An address is given to a computer by the router.
3. LAN Domain • Local Area Network (LAN) Domain is a collection of computers connected to one another or to a common connection medium. Connection mediums can include wires, fiber optic cables or radio waves. Includes physical network components and logical configuration of services for users. 4.
(Adesh Rampat, 2013) From the diagram below, we can see that there are many security, bandwidth, equipment, firewall, and system issues. First, the type of equipment they’re using is outdated (computer systems, tape systems, etc.) They’re still connecting using an Ethernet cable and are not utilizing a wireless connection. A single Ethernet cable, like an electric power cord, can extend only limited distances due to their electrical transmission characteristics. This is why wireless is so much more effective when it comes to running a network.
1. What is the Internet? The Internet is a globally interconnected network of computers that, operating via several specific protocols, serves as a worldwide information system and provides the technological infrastructure on which countless applications are run (Leiner et al., 2012; Woods, 2013a). At the hub of every network is a server, with the Internet essentially being formed through the connection of multiple servers, encompassing all connected computers and creating a larger ‘inter-network’ (Woods, 2013b). Each device on the network has a unique numerical address and the Internet uses the DNS (Domain Name System) to allocate each a corresponding human-readable address (Woods, 2013a).
Circuits needed to support * Pros: works well for static or slowly evolving network * Cons: Expensive and time consuming * 3 forces: making the traditional design less appropriate * The underlying technology of the client and server computers, networking devices, and the circuit themselves is changing very rapidly * The growth in network traffic is immense * With such rapid growth, it is no longer possible to accurately predict network needs for most networks. * The balance of costs have changed * Staff members cost > Hardware cost. * The building-block network design process: network that use a few standard components throughout the network are cheaper in the long run than networks that use a variety of different components on different parts of the network * Goal: simpler design process and more easily to manage * 3 steps * Needs analysis * Baseline, geographic scope, app system, network user, needs categorization * Technology design * Clients and server, clients and devices * Cost assessment * Off the shelf, request for proposal * Needs Analysis * Goal: why the network is being built and what users and apps it will support * Goal: produce a logical network design; statement of the network elements needed to meet the needs of the org * Geographic scope: the first step in needs analysis is to break the network 1.

9. A Signal driver is a device driver that includes a digital signature proving who published the device driver and whether the device driver has been altered. 10. Device manager provides you with a graphical view of the hardware that is installed in your computer and gives you a way to manage and configure your devices. Multiple Choice 1.
Assignment 5.1 Chapter 6 Section 6-1 2. Define Cisco IOS. Cisco IOS is the operating system used to configure all Cisco routers. It includes a CLI for inputting instructions to configure the Cisco router interface. Section 6-2 3.
Looking at the practicality of questionnaires it is possible at first glance to see many pros in their favour. Firstly, they are flexible in so far that they are able to be conducted face to face, by post, phone or via the internet. Similarly, they are a cheap way of collecting large amounts of data from large numbers of people, and with the people who conduct the research not needing any specific training they therefore also save money. However, this can come as a problem too. Having no power of the success of the questionnaire when sent out to the public means that there are often thousands of questionnaires wasted, proving to be a limitation rather than strength.
