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?

If it is to focused on detail it will overwhelm the reader with information and the reader won’t be able to take it all in effectively. Lab 3.1 Review 1. Why would a three- layer model of communication that has the layers
What is the purpose of dynamic host control protocol (DHCP)? DHCP allows a computer to join an IP-based network without having a pre-configured IP address. DHCP is a protocol that assigns unique IP addresses to devices, then releases and renews these addresses as devices leave and re-join the network. 3. What was the DHCP allocated source IP host address for “student” VM and target VM?
* “You can change a program's structure and thus directly affect its logical flow. Technically this activity is called patching, because it involves placing new code patches (in a seamless manner) over the original code” * Can be a learning tool * Can be used as a way to make new compatible products that are cheaper than what is currently on the market. * For making software interoperate more effectively or to bridge different operating systems or databases. * Used to uncover the uncoordinated features of commercial products. Disadvantages * “Manually translated source code often retains the style and flavor of the original implementation”.
Network Concepts and Apps- MIS 589 Week 3 - Text Book Questions. Question 1: What does Data link layer do? The data link layer is responsible for sending and receiving messages to and from other computers. Its job is to reliably move a message from one computer over one circuit to the next computer where the message needs to go. Its two main functions are data link layer’s connection to the network layer above it done by the sub-layer (logic layer Control (LLC)) and second function being done by the sub-layer MAC- Media access control which controls the physical hardware.
Networking 337 Exam 1 Cards What are properties of WANs? connects backbone networks and MANS. The _________ layer performs error checking which is redundant with the function of the _________ layer. transport, data link Which is a function of the transport layer? breaking long messages into several smaller messages The primary reason for networking standards is to: ensure that hardware and software produced by different vendors can work together ___________ refers to the spreading of the signal that different parts of the signal arrive at different times at the destination.
Another reason could be that it is cheaper to buy online than it is in stores. 2. Why would organisations prefer to use online forms to gather data than hardcopy forms? A. Organisations prefer to use online forms to gather data rather than hardcopies because it can reach out to many more people, maybe even people from different sides of the world. It is also much easier to keep track of data digitally rather than with hard copies.
The country’s that are involved will have different national interests that will create obstacles. c. If each country operated under individual C2 functions it will be difficult to achieve a unified command. d. The ability to form strong relationships of trust, mutual cooperation and understanding take time and testing. B. Advantages.
You cannot see a cause only two things happening in conjunction with one another. This to me makes me feel that the 2nd way – from Cause is not as strong as the other two arguments Aquinas puts forward. As Aquinas’ arguments are A Posteriori which means they come from experience, can Aquinas’ 2nd way really be A Posteriori? I do not think so as you are unable to experience a cause, therefore, the 2nd way cannot be convincing proof of the existence of God. Aquinas’ 3 ways make far too many leaps and assumptions.
