Rules Of Netiquette

Introduction Netiquette, or network etiquette, is concerned with the "proper" way to communicate in an online environment. Consider the following "rules," adapted from Virginia Shea's   The Core Rules of Netiquette , whenever you communicate in the virtual world. Rule 1: Remember the Human When communicating electronically, whether through email, instant message, discussion post, text, or some other method, practice the Golden Rule: Do unto others as you would have others do unto you. Remember, your written words are read by real people, all deserving of respectful communication. Before you press "send" or "submit," ask yourself, "Would I be okay with this if someone else had written it?" Rule 2: Adhere to the same standards of behavior online that you follow in real life While it can be argued that standards of behavior may be different in the virtual world, they certainly should not be lower. You should do your bes...

NETWORK TOPOLOGY

A network topology is the arrangement of a network, including its nodes and connecting lines. There are two ways of defining network geometry: the physical topology and the logical (or signal) topology. The physical topology of a network is the actual geometric layout of workstations. There are several common physical topologies, as described below and as shown in the illustration. In the   bus network   topology, every   workstation   is connected to a main cable called the bus . Therefore, in effect, each workstation is directly connected to every other workstation in the network. In the   star network   topology, there is a central computer or server to which all the workstations are directly connected. Every workstation is indirectly connected to every other through the central computer. In the   ring network   topology, the workstations are connected in a closed loop configuration. Adjacent pairs of workstations are direct...

About types of network topology

Bus Topology  –  It is defined by the use of a single main cable which has terminators on both ends. All the other nodes like workstations, peripherals, etc. are connected to this main cable. This type of topology is widely implemented in LANs as it is easy to install and does not cost much. It also does not require much cabling as in the case of some other topologies like star and mesh. The main disadvantage of this topology is that the entire network is dependent on the main cable. In case some problem occurs in the main cable, the whole system gets affected. Star Topology  – It is named as star topology as it looks similar to a star whereas all the elements of the network are primarily connected to a central device. This central device is known as hub and can be either of a hub, router or a switch. This central hub also works as a repeater for data flow. A point-to-point connection is laid between the devices and the central hub. Thus, all nodes are conn...
