Why was it created? Use your textbook and Internet research to support your answer. TCP/IP stands for Transmission Control Program(Protocol is the earlier version) and Internet Protocol. These two were created basically at the same time by 2 Darpa Scientists without one it would be hard to nearly impossible to have the other. This system was created because it was a way that any network could communicate with another through a gateway.
Zackery Skelton NT1210 Unit 3 Lab 3.1: Network Reference Models 1. Why would a three- layer model of communication that has the layers physical, network, and application be insufficient to adequately describe network communication? The three-layer model of communication would be insufficient to adequately describe network communication because because it would not have the ability to transport data to any other network. 2. What is the history of the OSI reference model?
4. (TCO F) The traditional network design approach does not work well for ____ networks. 5. (TCO F) Which of the following would not be a type of circuit that needs to be considered when planning for technology design capacity? 6.
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?
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.
B) Routing An IP network that is formatted such as 192.168.1.0/25 is referred to as what type of notation? A) CIDR notation. What is the default network protocol of the Internet and most modern corporate networks? D) TCP/IP What was used by TCP/IP networks to perform name resolution prior to the introduction of the Domain Name System? A) Hosts files.
In 1984, the International Organization for Standardization (ISO) adopted the Open Systems Interconnection (OSI) Reference Model (or OSI Model) to simplify interoperability amongst network devices. The OSI model delineates standard protocols for communication and interoperability by utilizing a layered approach. The OSI model is a conceptual model comprised of seven layers, each specifying particular network functions. This model is now considered the primary architectural model for inter-computer communications (Dubendorf, 2003). The OSI model
4. (TCO F) The traditional network design approach does not work well for ____ networks. 5. (TCO F) Which of the following would not be a type of circuit that needs to be considered when planning for technology design capacity? 6.
What was the DHCP allocated source IP host address for “student” VM and target VM? The DHCP allocated source IP host for VM is 172.30.0.4 and for Target VM is 172.30.0.8 4. When you pinged the targeted IP host, what was the source IP address and destination IP address of the ICMP echo request packet? souce = 172.30.0.2 target = 172.30.0.8 5. Did the targeted IP host respond to the ICMP echo- request packet with an ICMP echo- reply packet?
The essential element that allows this connection is the IP address. Unfortunately internet protocols were designed before mobility was an issue. Under standard IP, if a mobile node moves from one subnet to another it needs to be assigned a new IP address in order to maintain its connectivity. Since the majority of the traffic on the Internet uses TCP connection it means that the port numbers for the source and destination need to be maintained. Having in mind that when a new IP address is issued the pervious TCP connection needs to be taken down, it is obvious that the standard IP cannot really withstand a frequent movement of the nodes.
