U2L4 Routers and Redundancy & U2L5 Packets

CSP Conceptual Framework

CSN-1 - Computer systems and networks facilitate how data is transferred.

CSN-1.B - Explain how the Internet works.

CSN-1.B.5 - Routing on the Internet is usually dynamic; it is not specified in advance.

CSN-1.B.6 - The scalability of a system is the capacity for the system to change in size and scale to meet new demands.

CSN-1.C - Explain how data is sent through the Internet via packets.

CSN-1.C.1 - Information is passed through the Internet as a data stream. Data streams contain chunks of data, which are encapsulated in packets.

CSN-1.C.2 - Packets contain a chunk of data and metadata used for routing the packet between the origin and the destination on the Internet, as well as for data reassembly.

CSN-1.C.3 - Packets may arrive at the destination in order, out of order, or not at all.

CSN-1.C.4 - IP, TCP, and UDP are common protocols used on the Internet.

IOC-2 - The use of computing innovations may involve risks to your personal safety and identity.

IOC-2.B - Explain how computing resources can be protected and can be misused.

IOC-2.B.6 - Certificate authorities issue digital certificates that validate the ownership of encryption keys used in secure communications and are based on a trust model

CSTA K-12 Computer Science Standards (2017)

NI - Networks & the Internet

2-NI-04 - Model the role of protocols in transmitting data across networks and the Internet.

3A-NI-04 - Evaluate the scalability and reliability of networks, by describing the relationship between routers, switches, servers, topology, and addressing.

3B-NI-03 - Describe the issues that impact network functionality (e.g., bandwidth, load, delay, topology).
