Internet

A global network of interconnected computers that communicate using standardized protocols, enabling the exchange of data and access to various services and resources.

Computer Network

A group of computers linked together to share resources and communicate, often using specific protocols.

Computing System

A collection of hardware and software components that work together to perform computation, data processing, and provide services.

Computing Device

A device capable of processing data, which includes computers, smartphones, tablets, and other electronics that perform computation and run applications.

World Wide Web

A system of interlinked hypertext documents accessed via the internet using browsers.

Router

A networking device that forwards data packets between computer networks, enabling communication over the internet.

Internet Service Provider (ISP)

a company that provides individuals and organizations access to the internet, often offering various services including web hosting and email.

Bandwidth

The maximum rate of data transfer across a network path, measured in bits per second.

Cloud

A system of remote servers hosted on the internet to store, manage, and process data, rather than a local server or personal computer.

Path

The way the internet travels

Routing

the process of selecting the best path for data packets to travel from a source to a destination across one or more computer networks

Scalability

How far information can spread using peoples computers as jump points

Redundancy

Unnecessary points of whatevers that let programs run even if one unit breaks

Fault Tolerance

Ability to work after unit breaks

Protocol

the primary network-layer rule set that delivers data packets across networks from a source to a destination using unique numerical addresses.

IP Address

a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication

Packet

information

Packet Switching

a method of transmitting digital data across a network by breaking it down into small, manageable units called packets

Transmission Control Protocol/Internet Protocol (TCP/IP)

the foundational set of communication rules that allows computers and devices to talk to each other across the internet and private networks

Encryption

encryption

Decryption

decryption

Symmetric Encryption

a security method that uses a single, shared secret key to both encrypt plain text into unreadable ciphertext and decrypt it back into its original form

Public Key Encryption

Shared openly with anyone; used to encrypt a message or verify a digital signature.

SSL (Secure Sockets Layer) and TLS (Transport Layer Security)

cryptographic protocols that encrypt data transmitted between a web browser and a server to keep online communication private and tamper-proof

Certificate Authority

is a trusted organization that verifies the identity of a website, person, or device and issues a digital certificate to bind that identity to a cryptographic public key

Malware

any program or code intentionally designed to damage, disrupt, steal from, or gain unauthorized access to computer systems, servers, networks, or mobile devices

Keylogging

keylogging

Computer Virus

a type of malicious software (malware) that attaches itself to a host program or file, replicates by inserting its own code into other programs, and executes when an infected file is opened

Antivirus

antivirus

Firewall

a network security system that monitors and controls incoming and outgoing network traffic based on preset security rules

Phishing

scams

A Distributed Denial-of-Service (DDoS) attack

a malicious attempt to crash or slow down a targeted website, server, or network by flooding it with an overwhelming wave of internet traffic

Rogue Access Point

any wireless router, hotspot, or device connected to a corporate or private network without the knowledge or approval of the IT and security team
