Question 45 Which one of the following statements regarding the SIMILARITIES and DIFFERENCES between WANS (Wide Area Networks) and LANs (Local Area Networks) is INCORRECT? WANS and LANS may differ at Layers 3 and 4 of the OSI model in access methods, topologies and sometimes media. b. LANS connect nodes, such as workstations, servers, printers, and other devices, in a small geographical area on a single organization's network, whereas WANS use networking devices, such as routers and modems, to connect networks spread over a wide geographical area. c. Both WANs and LANs use the same protocols from Layers 3 and higher of the OSI model. d. LANs are mostly owned and operated by the companies that use them whereas WANs are owned and operated by telcos (telecommunications carriers), also known as NSPs (Network Service Providers) 11-2 What are artificial intelligence (Al) and machine learning? How do businesses use Al? Define artificial intelligence (AI) and the major Al techniques. Define an expert system, describe how it works, and explain its value to business. Define machine learning, explain how it works, and give some examples of the kinds of problems it can solve. Define neural networks and deep learning neural networks, describing how they work and how they benefit organizations. Define and describe genetic algorithms, and intelligent agents, Explain how each works and the kinds of problems for which each is suited.
