Lab 2.1: Connecting Computers Exercise 2.1.1 Media, Interface, Signal, Pattern, and Timing are all necessary to establish a network. Media is needed for the physical structure on which the signal will travel. Interface is needed so the computer can access the media. Signal is the means of transmission such as electrical signal. Pattern is the format for the signals to be interpreted.
Lab 5 Lab 5.2.1 Each NIC must have a unique MAC address because all data is forwarded based on the destination address so without it the switch wouldn’t know where to send the data. 5.2.2 Information on the Support tab: Address Type – DHCP IP Address – 10.39.108.176 Subnet Mask – 255.255.252.0 Default Gateway – 10.39.110.15 5.2.3 Physical address of the NIC for this connection: 00-0C-29-20-53-9E 5.2.4 Manufacturer of the NIC: VMWare 5.2.5 IP address of the NIC and default gateway: 10.39.108.176 10.39.110.1 5.2.6 Steps in an ARP Request and Response: Step 1: When a source device want to communicate with another device, source device checks its Address Resolution Protocol (ARP) cache to find it already has a resolved MAC Address of the destination device. If it is there, it will use that MAC Address for communication. To view your Local Address Resolution Protocol (ARP) cache, Open Command Prompt and type command "arp -a" (Without double quotes using Windows Operating Systems). Step 2: If ARP resolution is not there in local cache, the source machine will generate an Address Resolution Protocol (ARP) request message, it puts its own data link layer address as the Sender Hardware Address and its own IPv4 Address as the Sender Protocol Address.
Server can be configured, for example if you are in an organization and you know that certain website your employers wouldn’t need access or you want to block all the dodge websites, you can do that by configuring the server. If you but new computers you can easily add the new computer onto the system with no problem so it is very flexible. Disadvantage of client/server When there is a problem with the server, or it even shuts down the whole system will get affected. It might be a bit pricy to set up client/server It might also be costly to maintain all the client on the client/server, lots of skills needed to maintain the server in a proper way. [pic] This is an example of a client/server, as you can see the big computer is the server and all the other computer/devices are connected to the server.
Unit 7 Assignment Christopher Place Kaplan Online University Unit 7 Assignment Question 1 A Media Access Control Address (MAC Address) is also known as a physical address and is used on the media access control protocol sublayer and is assigned to routers ports to identify them to a physical address. The reason for the router having more than one MAC address is because it has two different ports assigned for different reasons and in this case it is for internet and LAN. An IP address is an address associated with every device on a network and a computer so that the internet knows where the web servers and mail servers can send their data to. The reason for the two different IP addresses on the router is because every router has two of them one is called the WAN interface or public IP address and the other is called LAN interface or private IP address. The WAN interface is the side that is connected to the internet which is why it is public and the LAN interface is the side that is connected to the network and that is why it is private.
Internet/the Internet: The global network formed by interconnecting most of the networks on the planet, with each home and company network connecting to an Internet service provider (ISP), which in turn connects to other ISPs. Link: A generic term for any network cable or wireless communications path between two devices over which bits can be transmitted. Node: A generic term for any networking device that sits on the end of links, for the purpose of both connecting links to create physical paths and to make decisions about how to forward data through the network. Protocol: A set of rules
Some of the things that NCP does include file access, printer access, security. Using TCP/IP (transfer control protocol) which is also on layer three and four of the model, and it allows a network to communicate through ort 80 or also known as HTTP (Hypertext Transfer Protocol. These protocols would be chosen based on the security, and the devices it needs to access the internet. In anything to do with networks and computers security is always number one so putting a WPA2 enterprise with a wireless router, in place would be very beneficial for Kudler so the router and the network can have a passcode in place so there will be no outside influences to hack the system. The authentication of the Radius server will be used for the WPA Enterprise which the router uses is 802.
1. IP hosts in two different company TCP/IP networks send IP packets to each to each other through the Internet. Which of the following is true about the Internet Connection that must exist so that the packets can flow between the two companies? B. The two companies must each have at least one Internet access link.
Question 1: Define and explain the following terminologies: Computer network; White (2013, p.3) defines computer network as “an interconnection of computers and computing equipment using wires or radio waves and can share data and computing resources”. It is basically an interconnection of computer systems comprising of devices such as servers, computers (desktop, laptop), tablets (iPads), mainframe and other hardware devices such as storage devices and printers. Its main purpose is to allow for communication between these computers and equipment so that the different users of the computers in the network can share data and resources. All networks have * a medium of communication that are either hard wired using copper cables, co-axial
The information contained in the wrapper tells computers what kind of data is in the packet, how it fits together with other data, where the data came from and the data's final destination. When you connect with someone on an online game, the information breaks up into packets that travel across the network. Different packets from the same information do not have to follow the same path. That's part of what makes the Internet so robust and fast. Packets will travel from one machine to another until they reach their destination.
