Computer Science Term 2

Computing Device

is an electronic machine designed to electronically acquire, store, process, analyze, and publish data or information.

Computing System

is a collection of integrated hardware, software, and potentially network components that work together to receive, store, process, and transmit data and information.

Computing Network

is a collection of at least two computing devices interconnected by hardware, software, and protocols to facilitate the sharing of information and resources.

Path

defines the location of a file or directory within a hierarchical file system, or a sequence of directories in the system's path environment variable that the operating system uses to find executable programs.

string of directory names and delimiters

Path is the? 

Bandwidth

a range of frequencies within a given band, in particular that used for transmitting a signal.

Protocol

is a standardized set of rules that dictates how data is formatted, transmitted, and received between devices on a network.

IP Address

a unique string of characters that identifies each computer using the Internet Protocol to communicate over a network.

Internet Protocol (IP)

is the standard set of rules for addressing and routing data packets across networks, enabling internet communication.

Router

a device that forwards data packets to the appropriate parts of a computer network.

Redundancy

is the deliberate inclusion of backup or duplicate components, data, or systems to ensure continuous operation and protect against failures, data loss, or other disruptions.

Fault Tolerant

is the ability of a system to maintain proper operation despite failures or faults in one or more of its components.

HTTP

(Hypertext Transfer Protocol) is an application layer protocol in the Internet protocol suite model for distributed, collaborative, hypermedia information systems.

Internet

a global computer network providing a variety of information and communication facilities, consisting of interconnected networks using standardized communication protocols.

Packet

is a small, structured unit of data transmitted across a network, like the internet.

Packet Metadata

is data about the data within a network packet, specifically information added to it to help route it through the internet and reassemble it at its destination.

Routing

is the process of selecting the most efficient path for data packets to travel from their source to their destination across a network.

UDP

(User Datagram Protocol) is a fast, connectionless communication protocol that sends data packets (datagrams) without establishing a connection or guaranteeing their arrival, order, or integrity.

World Wide Web

is an information system of linked hypertext documents that runs on the Internet, providing access to shared information through web browsers.

Certificate authority

is a trusted third-party organization that verifies the identities of entities (like websites or software developers) and issues digital certificates.

Digital Divide

refers to the gap between those who have access to and can effectively use information and communication technologies (ICTs) like computers and the internet, and those who do not.
