CS6250 Computer Networks Exam 1 Questions and Answers 100% Solved What are advantages and disadvantages of a layered architecture? ️️Each protocol layer offers different services. Some advantages are scalability, flexibility, and ease of adding / removing components making it easier for cost-effective implementations. Disadvantages include: some layers functionality depends on the information from the other layer and violates the goal of layer separation; one layer may duplicate lo...

INSY 3303 Exam 1 Questions and Answers Already Passed Three basic components of a network: A server, client, and a circuit. What is a client? Is the inout-output device at the user end. (I.E. clients computer) What is a circuit? It is the pathway through which a message (data) travels. Think everything in-between the server and client, connects them together. What is a server? Typically servers provide some service for the clients. (data access, application logic, etc) Types of networks: LAN...

What are advantages and disadvantages of a layered architecture? - Separation of concerns among logical layers promotes flexibility, scalibility, and maintainability. Multiple applications can reuse the components. It enables teams to work on different parts with minimal dependencies on other teams What are the similarities of the OSI model and five-layered Internet model? - They are both based on layered architecture. The are comparable to each other - see image 1 Both are networking stand...

CISA EXAM QUESTIONS AND ANSWERS ALREADY PASSED A bridge operates at level 2 of the OSI layer and is used to connect two LANs using different protocols (e.g., joining an ethernet and token network) to form a logical network. Bridges reduce the amount of traffic on a LAN by dividing it into two segments. Bridges inspect incoming traffic and decide whether to forward or discard it. An Ethernet bridge, for example, inspects each incoming Ethernet frame - including the source and destinatio...
