Document Summary

Disseminate information (e. g. , event invites, job postings) Backup data (to facilitate recovery of lost/corrupted data) Remote operation (e. g. , home monitoring, nest thermostat) Describes interaction of networked computers: clients request information from servers, servers respond with the information (if applicable) Misleading, as any computer can act as a client or server.

Bandwidth: the amount of data transmitted along a communication path in each unit of time; typically expressed in bits per second (bps) Latency: the amount of time it takes for a piece of data to travel between two points in a network. Developed by xerox parc in mid 1970s. Commercialized and standardized (called ieee 802. 3) in early 1980s. Used to implement local area networks (lans) in home, schools, and businesses.
