Step by step
Solved in 3 steps
- Explain the OSI model and its seven layers, detailing the functions and protocols associated with each layer.SaaS Architecture: • What does a client need in order to be able to contact a webserver? • What is an IP address? • Why is a port number necessary? • What is the system that makes it possible to contact web servers via friendly names instead of IP addresses? • What is the difference between an HTTP route and a URL/URI? • What are cookies and why are they useful? • What are common examples of HTTP clients? • What does REST stand for? • Who was REST invented by? • REST thinks about things in terms of [blank] and operations on those [blank]. • Know how to implement URLS for standard Create, Read, Update, and Delete Operations using REST.Explain the functionality and significance of a proxy server within the OSI model, including the layers it operates on.
- How does the OSI model relate to network virtualization technologies, such as Software-Defined Networking (SDN) and Network Function Virtualization (NFV)?what do you think some of the advantages and disadvantages of client-server configurations of networks?In the OSI model, three layers divide the application layer from the network layer: presentation, session, and transport. The application layer is closest to the end user and the network layer is closest to the physical network. Based on the functions of the three layers between application and network, how do you anticipate the implementation of these layers changes from application to network, as information is moved from one layer to another? What is the importance of understanding the functions of these layers? How are layers represented in the TCP/IP model?
