Roman Katoliko NT1210 CHAPTER 3: Building TCP/IP Networks Lab 3.1: Network Reference Models Ex 3.1.1 What would happen if wireless devices were not governed by the Wi-Fi Alliance and each vendor had its own standards and protocol? What impact would this have on your personal life or business communications? If each vendor had their own standards and protocols‚ we would have a harder time making devices that we use every day to inter-operate. Imagine buying specific BRAND of ROUTER for

Abstract The Open Systems Interconnect (OSI) model is a standard reference model for the communication between two end users. Seven different layers make up the OSI model: physical‚ data link‚ network‚ transport‚ session‚ presentation‚ and application. This paper will cover the type of security that is associated with each level of the OSI model. Physical Layer The physical layer is where the actual communication occurs between devices. The security of the physical layer pertains to the

Describe the three modes of communication available on a network. (Minimum word count: 60) Simplex - Data travels in only one direction‚ similar to a public address (PA) system Half-duplex - Data travels in two directions‚ but in only one

Flow Control – Data Link and Transport Layer. c. Interface to Transmission Media – Physical Layer. d. Provides access for the end user – Application layer. 4. Match the following to one or more layers of the OSI (TCP/IP) model: a. Reliable Process to process message – Transport Layer. b. Route Selection – Network Layer. c. Defines

systems are based on the reference model OSI-RM (Open System Interconnection-Reference Model) Description of OSI-RM System: OSI-RM is an International Standard ISO that defines a set of rules worldwide valid for designing the communication protocols‚ with a view to facilitating the interconnection of the hardware and software devices‚ no matter their producer [1‚ 2]. The structure of this model is highlighted in figure 1. As this figure presents‚ this model allows the transfer of data flow among

Exercise 3.2.4 Because the upper layers of the OSI model are for getting the information ready to be viewed. By the time the information needs to go through the upper layers‚ it has already reached its destination. Review 3.2 1) ? 2) Even though the OSI model is not directly implemented in networking‚ it still endures because it is basically a good “rule of thumb” and it sets a sort of idea on how things

ATM is a technology that will enable carriers to capitalize on a number of revenue opportunities through multiple ATM classes of services; high-speed local-area network (LAN) interconnection; voice‚ video‚ and future multimedia applications in business markets in the short term; and in community and residential
