Computing Device

• a group of interconnected computing devices capable of sending or receiving data.
• a machine that can run a program, including computers, tablets, servers, routers, and smart sensors
• the system responsible for translating domain names like example.com into IP addresses
• the series of connections between computing devices on a network starting with a sender and ending with a receiver.

Computing System

• a system of linked pages, programs, and files.
• a group of interconnected computing devices capable of sending or receiving data.
• the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second.
• a group of computing devices and programs working together for a common purpose

Computing Network

• a group of interconnected computing devices capable of sending or receiving data.
• the series of connections between computing devices on a network starting with a sender and ending with a receiver.
• a computer network consisting of interconnected networks that use standardized, open (nonproprietary) communication protocols.
• the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second.

Path

• a computer network consisting of interconnected networks that use standardized, open (nonproprietary) communication protocols.
• the series of connections between computing devices on a network starting with a sender and ending with a receiver.
• a group of interconnected computing devices capable of sending or receiving data.
• a group of computing devices and programs working together for a common purpose

Bandwidth

• the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second.
• HyperText Transfer Protocol - the protocol used for transmitting web pages over the Internet
• a system of linked pages, programs, and files.
• the system responsible for translating domain names like example.com into IP addresses

Protocol

• a machine that can run a program, including computers, tablets, servers, routers, and smart sensors
• a group of interconnected computing devices capable of sending or receiving data.
• a group of computing devices and programs working together for a common purpose
• An agreed-upon set of rules that specify the behavior of some system

IP Address

• HyperText Transfer Protocol - the protocol used for transmitting web pages over the Internet
• 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.
• The unique number assigned to each device on the Internet.
• the series of connections between computing devices on a network starting with a sender and ending with a receiver.

Internet Protocol (IP)

• a protocol for sending data across the Internet that assigns unique numbers (IP addresses) to each connected device
• a group of interconnected computing devices capable of sending or receiving data.
• the series of connections between computing devices on a network starting with a sender and ending with a receiver.
• a computer network consisting of interconnected networks that use standardized, open (nonproprietary) communication protocols.

Router

• a computer network consisting of interconnected networks that use standardized, open (nonproprietary) communication protocols.
• A type of computer that forwards data across a network
• a group of computing devices and programs working together for a common purpose
• the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second.

Packet

• a group of interconnected computing devices capable of sending or receiving data.
• a machine that can run a program, including computers, tablets, servers, routers, and smart sensors
• 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.
• a system of linked pages, programs, and files.
