Chapter 9 1. IP hosts in two different company TCP/IP networks send IP packets to each other through the Internet. Which of the following is true about the Internet connections that must exist so that the packets can flow between the two companies? a. The two companies must connect directly to each other.
Originally, the message transmitted to the recipient was the telephone number of the sender basically requesting a call back. Soon after, two way pagers where developed. They allow an interactive system of communication between the sender and receiver. Pagers operate on a data network. VOIP phones- voice over internet protocol is a technology that allows phone calls to be made through the internet.
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.
5. Which of the following lists a correct match between the IP address and its class? A. 102.1.1.1, class A 6. A user opens a Web browser and types in a URL that lists the name of a server.
Unit 1. Exercise 1. Local Exchange Data travels across the internet in packets. Around these packets is a wrapper with a header and a footer. 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.
Routers R1 and R2 are directly connected via their serial interfaces and are both running the EIGRP routing protocol. R1 and R2 can ping the directly connected serial interface of their neighbor, but they cannot form an EIGRP neighbor adjacency. What action should be taken to solve this problem? Configure both routers with the same EIGRP process
Describe the application layer of the TCP/IP model. (p344) Application layer roughly correspond to the OSI application and presentation layers and includes many protocols. 4. Describe the network interface layer in the TCP/IP model(p 344) Network interface layer roughly equivalent to the OSI data link layer. This layer connects internet protocol to underlying network protocols in the physical layer.
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.
The direct data packet generated by Network Layer using information that is stored in a table known as routing table. Routing table is a list available destination which enables the network layer to work with logical
