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

Q1 Solution: Computer network: the connection of computers and computing peripherals either using wires or radio waves over a small or large geographical areas. E.g. interconnection of many computers to a single printer. Depending upon the area covered computer network can as classified as PAN, LAN, MAN and WAN. Personal Area Networks: an interconnection of devices in few meter distance which is connected wirelessly. E.g. connection of mobile phone over a wifi signal to a router. Local area networks:

Chapter 3 Review 1. Which of the following is true about a TCP/IP network? A) The network uses only standards defined in TCP/IP RFCs. 2. Which of the following terms is not a common synonym for TCP/IP model? (Choose two answers.) D) TCP/IP mapping and C) Ethernet 3. Think generically about the idea of a networking standard, ignoring any particular standard or standards group. Which of the following is typically true of a standard? (Choose two answers.) B) It exists as a deployed network device

This layer compares to the Network layer of the OSI model. • TRANSPORT LAYER provides the Application layer with session and datagram communication services. TCP and UDP are the core protocols at this layer. TCP provides a one-to-one, connection-oriented, reliable communications service that establishes

Throughout chapters 5 through 8, many topics have been discussed in class and practiced on lab days. Starting off with chapter 5, OSI Network Layer: various topics are discussed which include; IP v4, the Network Layer, to routing tables. The basic characteristics of IP v4 are that it is connectionless, the best effort is unreliable and is unaware of the quality of its job, and it is also media independent. Time to Live (TTL) is the 8-bit TTL field that describes the maximum hops that a packet

ASA College CIS 125-M01: Network Concepts Networking Standards (OSI Layers) Joel Hernandez Vasquez joelvasquez@asa.edu 02/09/2016 Nowadays everybody can get access to the internet through networks, but according to Columbia University over the 37% of people do not know what a network is. A network is a group of computers which are connected to share information, files, and performs tasks. A network is built using the same common language. My purpose of this project is to explain what a network

and the most complex to troubleshoot. [Ste1999] VPN technology is a very secure and basic technology which is used world-wide. Different type of VPN technology functions of different types of OSI layer. Figure 1 will show how each layer of VPN technology is related to the OSI (Open System Interconnection) model. The comparison

introduces us to the two main protocol standards use for communication. This paper briefly explains the key aspects of these two well known protocol suites namely; Open source Interconnection (OSI) and Transmission Control Protocol/Internet Protocol. The former is also called as Basic Reference model or the OSI model consisting of seven different layers where each layer
