Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio. With radio waves distances can be short‚ such as a few meters for television or as far as thousands or even millions of kilometers for deep-space radio communications. It encompasses various types of fixed‚ mobile‚ and portable applications‚ including two-way radios‚ cellular telephones‚ personal digital assistants

Comparison of Vulnerability Assessments and Penetration Testing Abstract: Internet has opened unlimited avenues of opportunity by enabling organizations to conduct business and share information on a global basis. However‚ it has also brought new levels of security concerns and Cyber threats. It exposes valuable corporate information‚ mission critical business applications and consumer’s private information to more risk than before. But security of IT infrastructure is something that Organizations

History of LANs Data Communications began in the 1960s with an emphasis on communication over long distances — at least between different cities and often over much greater distances — but at relatively slow data transfer rates. At that time‚ that was what was needed. Most computing was done in batch mode‚ and companies needed an efficient way to transmit data processing files between computer sites. In the 1970s‚ interactive terminals began to proliferate‚ but most data communications took place

Abstract Vulnerability literally means to be exposed physically or mentally. It is basically uncertainty‚ insecurity‚ and risk. In day to day life‚ people tend to drive away from situations that might expose their emotional or physical weaknesses by perfecting themselves. But life is not all black and white. It is a series of ups and downs‚ good and bad. The reason people avoid risk and uncertainty is scarcity. The fear of never being good‚ perfect‚ beautiful‚ secure‚ rich‚ secure enough. When people

1. What are the main architectural components of a LAN? (Minimum word count: 60) The first characteristic in the LAN architecture is the physical arrangement of the network. This is how the nodes connect. The topology of an LAN is the design pattern of interconnections between the computers and network sectors. The second component is the method of access for the nodes. Specifically‚ how the nodes connect to the transmission medium. A network interface card is a device that permits computers

TED Talk on The Power of Vulnerability Summary Brene’ Brown‚ a social work researcher discusses the sense of vulnerability in human society and how it plays a major factor within our lives. In her research‚ Brown studies how certain emotions relates to the power of vulnerability and why this takes place. After six years of gathering and studying data on human emotions‚ she finds that it is very common for people to numb their emotions or to disregard them‚ in order to feel less vulnerable. In this
