What is the history of the TCP/IP model? Why was it created? Use your textbook and Internet research to support your answer. In 1970's the DOD sponsored a project to create a standardized networking model called TCP/IP. Pg 61 - 3.2.1 exercise 3.2.1 Using Figure 3-1, define each layer of the OSI model in your own words and state what each layer provides.
Suppose the university has the 128.100.xxx.xxx address range on the Internet. How would you assign the IP addresses to the various subnets? How would you control the process by which IP addresses are assigned to individual computers? You will have to make some assumptions to answer both questions, so be sure to state your assumptions. As a network manager, I would assign the IP addresses to various subnets by associating a subnet base address with each physical network.
d. The two companies must each connect to a Tier 1 ISP. Answer: B. to send packets through the Internet, a company needs just one connection to an ISP. The ISP then commits to having connections to the rest of the Internet. The two companies do not need a connection to each other, or even to the same ISP. 2.
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.
General Questions 1. Periodization can be defined as the attempt to divide time into sections or blocks. 2. A theoretical issue with periodization is that any chronological pattern of events can obscure another. The organizational problem with periodization is that because there are so many things happening at one time, a historian is not able to focus on them all.
Cable internet is a broadband connection with a Ethernet handoff to the customer that fits right into the existing network. Additionally, this layout would be very similar to what Northeastern Health Services, Inc. staff have seen at home and other locations. Third, Northeastern Health Services, Inc. would evaluate the complexity of the innovation. Again, cable internet is a simple hand off to the customer and should integrate seamlessly into the existing network design. Fourth, Northeastern Health Services, Inc. would evaluate the trialability of the innovation.
Voice or data computers, network interfaces, and transmission medium C. Modems, transmission links, and wireless access points D. TCP/IP software, modems, and transmission links Correct! The correct answer is: B. âA network consists of two or more connected computersâ (Laudon & Laudon, 2011, p. 194). âBasic network components include computers, network interfaces, a connection medium, network operating system software, and either a hub or a switchâ (p. 225). Networking and telecommunications technology, consisting of both physical devices and software, links the various pieces of hardware and transfers data from one physical location to another. 2.
Part A 1. What were the primary reasons for changing the current system? The primary reason for Butler wanting to change over to a VoIP system was that their existing phone system provider, Centrex, was not fully meeting Butler's needs. The older system did not provide modern features, and adding or changing phone lines was labor intensive. (Brown, Dehayes, Hoffer, Martin & Perkins, 2012, p. 144) 2.
In The Shallows: What the Internet Is Doing to Our Brains, the author, Nicholas Carr gives an in-depth description of the advances in technology and what effect these advancements have done to our society. Carr gives examples of the effects of several different types of modern technology but concentrates mostly on the effects of the Internet. This book is particularly persuasive in the way Carr argues and backs his idea with personal experience and opinions. In this paper, I will apply Carr’s idea of the Internet as a medium way people read and process information to my own experiences as a reader. I will focus, specifically, on my reading process; how it is changed, for better or worse, depending on such things as genre and the impact of the
2. Which layer of the TCP/IP model processes requests from hosts to make sure a connection is made to the appropriate port? i. Application Layer 3. What are well known ports?
