User experience designUser experience design (UX design, UXD, UED, or XD) is the process of defining the experience a user would go through when interacting with a company, its services, and its products. Design decisions in UX design are often driven by research, data analysis, and test results rather than aesthetic preferences and opinions. Unlike user interface design, which focuses solely on the design of a computer interface, UX design encompasses all aspects of a user's perceived experience with a product or website, such as its usability, usefulness, desirability, brand perception, and overall performance.
Network congestionNetwork congestion in data networking and queueing theory is the reduced quality of service that occurs when a network node or link is carrying more data than it can handle. Typical effects include queueing delay, packet loss or the blocking of new connections. A consequence of congestion is that an incremental increase in offered load leads either only to a small increase or even a decrease in network throughput.
Social controlSocial control is a concept within the disciplines of the social sciences. Social control is described as a certain set of rules and standards in society that keep individuals bound to conventional standards as well as to the use of formalized mechanisms. The disciplinary model was the forerunner to the control model. The term "social control" was first introduced to sociology by Albion Woodbury Small and George Edgar Vincent in 1894; however, at the time, sociologists only showed sporadic interest in the subject.
