Standard Identifier:
9-12.NI.4
Content Area:
Computer Science
Grade Range:
9–12
Concept:
Networks & the Internet
Subconcept:
Network Communication & Organization
Practice(s):
Developing and Using Abstractions (4.1)
Standard:
Describe issues that impact network functionality.
Descriptive Statement:
Many different organizations, including educational, governmental, private businesses, and private households rely on networks to function adequately in order to engage in online commerce and activity. Quality of Service (QoS) refers to the capability of a network to provide better service to selected network traffic over various technologies from the perspective of the consumer. Students define and discuss performance measures that impact network functionality, such as latency, bandwidth, throughput, jitter, and error rate. For example, students could use online network simulators to explore how performance measures impact network functionality and describe impacts when various changes in the network occur. Alternatively, students could describe how pauses in television interviews conducted over satellite telephones are impacted by networking factors such as latency and jitter.
