10.10.0.10 Question 12 What value is configured in the DNS Servers: line? 10.10.0.10 Question 13 What is the default location for DHCP server backups? C:\windows\system32\DHCP\co-occurrence\ Question 14 What IP address is configured on the SEA-SVR2computer? 169.254.209.252 Question 15 What appears in the IP address text box? 10.10.0.55 Question 16 From which DHCP server are you receiving an IP address?
TCP is the transport layer protocol that links the application layer to the network layer. TCP breaks the data into smaller packets, numbers the packets, ensures each packet is reliably delivered, and puts the packets in the proper order at the destination. IP is the network layer protocol and performs addressing and routing. IP software is used at each of the computers through which the message passes through; IP routes the message to the final destination. TCP/IP is the transport & network layer protocol used on the Internet.
You are a consultant working on a site plan for a medium-sized organization. The organization consists of a main office and three branch offices. Two of the locations have standard IP links to the main office, while the third branch office is a separate domain and uses an Internet connection for e-mail. How should you configure the site links for the three branch offices to the main office? A: RPC over IP for the two standard link branch offices and use SMTP for the remote site.
UNIT 33: THE IMPACT OF COMMUNICATIONS TECHNOLOGY ON BUSINESS Describe how the internet operates 1. What is the internet? When and how did it start? The Internet, sometimes called simply "the Net," is a worldwide system of computer networks (a network of networks in which users at any one computer can, if they have permission they get information from any other computer (and sometimes talk directly to users at other computers). the 1960s and 1970s, the US Department of Defense funded programs where computer scientists were paid to develop Internet protocols.
Questions and Answers for Lab #5 1. What is the purpose of address resolution protocol (ARP)? Address resolution protocol converts IP addresses to ethernet addresses. 2. What is the purpose of dynamic host control protocol (DHCP)?
The Windows 7 command-line utility that can tell you if the TCP/IP stack of another system on the network is functioning normally is called __________________. Ping.exe 7. The Windows 7 command-line utility that enables you to generate DNS request messages and then transmit them to specific DNS servers on the network is called __________________. Nslookup.exe 8. Most networks use __________________ to dynamically assign addresses and configure computers to use them.
Chapter 5 –CQ4-Questions and Problems Section 5-2 1. What is a Bridge? Answer: Is a layer 2 device in the OSI model that uses the MAC address information to forward data and interconnect two LAN’s. 2. Define a segment.
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). Information is requested from a server and is sent using the packet switching and TCP/IP (Transmission Control Protocol/Internet Protocol) system (Jamison, 2001; Woods, 2013b). This involves breaking large files into smaller ‘packets’, allocating each packet addressing information, and sending them via different routes to be reassembled – including verification – at their destination (Jamison, 2001). Constantly evolving, the Internet has become an all-encompassing social, communicative and collaborative tool that is arguably essential to modern life (Leiner et al., 2012). 2.
