Introduction Network architecture is a combination of topology and protocols. In this paper‚ I will discuss topology‚ which is the defined as the shape of a network or how a network is laid out. Topology also consists of how the different components or nodes of a network are connected and how they communicate with each other. Topologies are either logical or physical. In addition‚ in the sections of this paper‚ I will compare and contrast some different conventional architecture and what types of

Carrier Sense Multiple Access with Collision Avoidance. However‚ simple CSMA is susceptible to the hidden node problem‚ especially in so called ad hoc networks where a node may communicate directly with every other node in range or using intermediate nodes as relays otherwise. Hidden nodes cause costly packet collisions and thus significantly affect network performance. In order to combat the hidden node problem‚ a mechanism known as Request to Send/Clear to Send (RTS/CTS) handshake is often used. RTS/CTS

single area. I also learned how to function a fully functional network in which each router has connectivity to all other networks. I learned how to configure OSPF‚ determine IP routing status by reviewing the IP route table‚ migrate from IGRP to OSPF routing‚ and how to verify network connectivity using ping and verify OSPF neighbor adjacencies. I will benefit in my academic and professional career by furthering my knowledge in the network world and giving me a stable and future job. Copy and Paste

Computer Lab or Computers in the Classroom Everyone lives in a society dependent on technology at work‚ home‚ and school‚ but students are not able to access this technology on a continuous basis. Computers are significant to education because they make us reconsider how students learn‚ how they are inspired‚ and what useful information is. Classroom with computers have become an important part of the curriculum and need to be used daily. Phasing out computer labs and putting computers right in

Our topic is that social networks encourage people to have good “interpersonal skills”. According to the research‚ the most popular method of communication among teens is social network. This format is an opportunity for teenagers to practice and develop social skills. Firstly‚ social network provides a virtual place to spend time and share thoughts and objects with personal meaning‚ such as pictures and stories‚ and remain closely connected with friends regardless of geographic distance. For example

This means that not only are we protected against intrusion at the network layer‚ the firewall will also protect against any application resources that we implement. Different firewall policies can be configured for

Cartoon network Cartoon Network (CN) is an American cable television network owned by Turner Broadcasting which primarily airs animated programming . The channel was launched on October 1‚ 1992‚ after Turner purchased the animation studio Hanna-Barbara Productions in 1991. It was originally a 24-hour outlet for classic animation properties from the Turner Broadcasting libraries and was all-ages-oriented‚ but now the channel targets kids and teens (about ages 8-15) with mature content during

However‚ with daily technology advancements made in society and the requirement for global data connectivity‚ satellites are increasingly being used to provide data communication links at all data rates ranging from 64 Kbps to 155 Mbps (Buchsbaum). Wireless technology allows data to be sent out into space to a satellite and back to earth to provide connectivity among many different network clients. The network can be designed to
