RADIO DETECTION AND RANGING
RADAR
LIGHT DETECTION AND RANGING
LIDAR
each device on a network
Node or Host
a powerful computer that acts as a hub for other devices on a network
Server
the study of computers and how they work
computer science
two types of digital footprints
active and passive footprints
A set of rules governing the exchange or transmission of data between devices.
protocol
uses laser light pulses to measure distances
LIDAR
converting code into an understandable form of communication
decode
A network node used to connect two networks with different transmission protocols together
gateway
Data collected without you actively sharing it (websites you visit).
Passive Footprint
Connects multiple nearby computing devices within one location.
Local-Area Network (LAN)
The speed at which data is transferred on a network from one device to another
Bandwidth
data written in a formation the computer will understand
encode
The trail of information you leave behind when you use the internet or digital devices.
Digital Footprint
uses radio waves to detect objects and measure how far away they are.
RADAR
Small chunks of information that have been carefully formed from larger chunks of information
Packets
Information you share intentionally (posts, comments, photos).
Active footprint
A set of connected computing devices that communicate and share resources, such as data or a printer
Network
Connects multiple LANs, usually over great distances, allowing communication between smaller networks. The internet is the most important and popular WAN
Wide-Area Network (WAN)
It governs how packets are routed through all the complicated networks on their way to their final destination.
Internet Transfer Protocol (IP)
A collection of citizens and volunteers interested in defining the standards of the Internet.
Internet Engineering Task Force
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.
Trasmission Control Protocol (TCP)
A system of symbols, letters, and numbers used to represent something else
Code
The process of breaking messages down into packets, transmitting them, and then reassembling them in the correct order.
