Unit 2 - The Internet Flashcards
Computing Device
A machine that can run a program, including computers, servers, routers, and smart sensors
Computing System
A group of computing devices and programs working to gather for a common purpose
Computing Network
A group of interconnected computing devices capable of sending or receiving data
Path
The series of connections between computing devices on a network starting with a sender and ending with a receiver
Bandwidth
The maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second
Protocol
A agreed-upon set of rules that specify the behavior of some system
IP Address
The unique number assigned to each device on the internet
Internet Protocol (IP)
A protocol for sending data across the Internet that assigns unique numbers (IP addresses) to each connected device
Router
A type of computer that forwards data across a network
Packet
A chunk of data sent over a network. Larger messages are divided into packets that may arrive at the destination in order, out-of-order, or not at all
Redundancy
The inclusion of extra components so that a system can continue to work even if individual components fail, for example by having more than one path between two connected devices in a network
Fault Tolerant
Can continue to function even in the event of individual component failures. This is important because elements of complex systems like a computer network fail at unexpected times, often in groups
HTTP
HyperText Transfer Protocol- the protocol used for transmitting web pages over the Internet
Internet
A computer network consisting of interconnected networks that use standardized, open communication protocols
World Wide Web
A system of linked pages, programs, and files
