Internet

global interconnected networks

Maximum bits

Redundancy

Data Packet

A piece of information transmitted digitally.

IP Address

A unique numerical label assigned to each device in a network.

Layers of the Internet

Different levels involved in internet operations, like protocols and networks.

Digital Divide

Disparities in availability and quality of internet connection.

Concept Mapping

Creating connections between various terms for a comprehensive understanding.

Bandwidth

The capacity of data that can be transferred in a specific time.

HTTP

Router

A device directing data traffic between computer networks.

Fault Tolerant

TCP

Transmission Control Protocol - provides reliable, ordered, and error-checked delivery of a stream of packets on the internet. TCP is tightly linked with IP and usually seen as TCP/IP in writing.

UDP

User Datagram Protocol. Used instead of TCP when guaranteed delivery of each packet is not necessary. UDP uses a best-effort delivery mechanism.
