ITS 315: Introduction to Networks Mazen Alkhatib December 23‚ 2012 Network Implementation Over four months‚ a very short period of time‚ a small accounting firm grew from five employees to fifty. The existing network architecture could no longer support the exponential growth. Peer-to-Peer networks work very well in a small office environment. Once the ratio of employees exceeds around five employees resources‚ file storage and a plethora of other network disasters begin. The obvious

Analysis and Countermeasures of Network Security LiuBingyao Abstract This article is concerned about network security. It mentions about the present situation of network security and an analysis of the reason that lead to unsafe network environment. Then the article introduces two frequently used protocols in network security: HTTP (Hypertext Transport Protocol) and HTTPS (Hypertext Transfer Protocol over Secure Socket Layer)‚ then compare them and give a brief conclusion. On the other side

large number of other nodes‚ they have the ability to measure a given physical environment in great detail. Thus‚ a sensor network can be described as a collection of sensor nodes which co-ordinate to perform some specific action. Unlike traditional networks‚ sensor networks depend on dense deployment and co-ordination to carry out their tasks. Previously‚ sensor networks consisted of small number of sensor nodes that were wired to a central processing station. However‚ nowadays‚ the focus is

Topic 2: Understanding Network Protocols I. What is a network? A computer network‚ or simply a network‚ is a collection of computers and other hardware interconnected by communication channels that allow sharing of resources and information. LAN - Connects devices within a single office or home or among buildings in an office park. The key aspect here is that LAN is owned entirely by a single organization. - In simplest conception‚ it consists of

that match the cable type of the network. Most common hubs interconnect Category 3 or 5 twisted-pair cable with RJ-45 ends‚ although Coax BNC and Fiber Optic BNC hubs also exist. Ethernet Hubs An Ethernet hub is also called a multiport repeater. A repeater is a device that amplifies a signal as it passes through it‚ to counteract the effects of attenuation. Multistation Access Unit A Multistation Access Unit (MAU) is a special type of hub used for token ring networks. Switches Switches
