Coaxial cables are advantageous because they support multiple channels and have a high bandwidth and low error rates. However, they are disadvantageous because they are susceptible to security risks, damage, congestion and noise, and they are costly to install.Know More
Coaxial cables are suitable for long distances, and they are available in multiple sizes. Using coaxial cables instead of twisted-pair cables increases network distance by 500 meters. Coaxial cables can support many services, including multimedia, video, data and voice. In coaxial cable transmission, each channel has a high capacity, depending on the location of the service. A coaxial cable has a shielded copper wire, which safeguards against electric noise in a network, leading to lower error rates.
Coaxial cable technology has been present for many years in data communication. A coaxial cable costs less than a fiber-optic cable. However, coaxial cables are susceptible to electromagnetic and radio frequency interference and may transfer noise between components of a network. If lightning strikes a coaxial cable, it conducts it and burns equipment at its end. Coaxial cables lose signal in long distances, but they are suitable for home use. Individuals should consider the size of a coaxial cable because it is difficult to work with thick cables and pass them through existing troughs and conduits that are limited in size.Learn more about Television & Video
Quantitative methods are advantageous because they allow researchers to conduct a broad survey, which involves many subjects and generalization of findings. They also yield accurate results. On the other hand, quantitative methods are rigid and provide less detail on the motivation, attitudes and behavior of study subjects.Full Answer >
Decentralization is advantageous in that it allows a company to simplify expansion, delegate and divide responsibilities among departments, and improve diversity and product emphasis. Drawbacks of decentralization include a lack of uniformity in company policies, higher finance costs, internal conflicts and ownership's loss of authority.Full Answer >
Total quality management (TQM) is advantageous because it provides companies with short-term and long-term benefits that improve product quality, productivity and customer relations. On the other hand, TQM can cause job loss, excessive costs during production and a decrease in creativity.Full Answer >
Achievement tests are advantageous because they provide an objective way to evaluate student abilities. Problems with these tests include an unfair disadvantage to non-native English speakers and teachers spending significant amounts of class time to teach exam materials.Full Answer >
