For devices to communicate they need an arrangement to communicate in a given language. This arrangement is governed by a set of rules or laws called a protocol. The protocol must define many different aspects of the communication language however given rules dictate that a protocol must as least classify The rate of transmission (baud or bps) Synchronous or asynchronous Half-duplex or full-duplex mode There are a variety of standard protocols from which programmers can choose. Each has particular

Lab Exercise 2.03: Recognizing External Connections Is it possible to plug any cable into the wrong connector? If so‚ which one(s)? What do you think would happen if you plugged something into the wrong connector? Answer- Yes‚ the mouse and keyboard connectors. If they plug into the wrong connector‚ the device will not work.

It is important to test the cables before you install them and after they are installed. Although there are many tools that are used for testing the cables in a network this paper is only going to talk about three. The first one is the multifunction cable scanner‚ they are available for testing both copper and fiber optic cable. One such model is the Hobbes 258898 it can test every pin of almost 20 often used cables from coax to 40 pin ribbon cables. It identifies opens‚ shorts and mis-wires at

Choosing the appropriate LAN device‚ cost of the whole job which is a major factor‚ and device interconnections. Knowing your codes are very important as well. When it comes to choosing the appropriate LAN device this is extremely important. Choosing the right router plays a part‚ some routers only work with certain

Eric Scantlebury NT1310 Physical Networking Unit 3 Assignment 1: Network Topology Paper 4/8/14 There are many different types of network topologies. They each have their different strong points. They also have their own disadvantages. There are 3 main network topologies used today‚ hierarchical star‚ bus and ring. In the following paragraphs I will go into each of these topologies. The first network topology is hierarchical star‚ also known as the tree topology. This topology has different levels

VLAN IT/242 VLAN Virtual Local Area Networks (VLAN) are beneficial because they improve security and bandwidth consumption. The call center has expanded taking up space on other floors causing part of the Engineering department and the Operations department to move offsite. All of the departments still need to be connected so that their data is still accessible to each other despite the expansion. A VLAN will allow these employees to continue to connectivity with their groups and

A VLAN Plan Katherine Cunningham Axia College of University of Phoenix January 31‚ 2010 A VLAN Plan As corporate computer networks have grown more complex‚ so too has the need to maintain a logical layout of these networks. For example‚ a local company may have the need for more customer service associates for their call center than it can comfortably hold while the engineering department does not take up even half of their floor. Using a virtual local area network (VLAN)‚ the network
