Networking Concepts Quiz

A software application that translates human-readable domain names into machine-readable IP addresses. It acts like a phonebook for the internet, allowing you to access websites by using their easy-to-remember names instead of their complex IP addresses.

A protocol used to establish a secure connection over a public network. It creates a virtual tunnel, encrypting all data transmitted between two points, making it difficult for unauthorized parties to intercept information.

A set of rules and procedures that govern how data is transmitted over a network. It defines the format, encoding, and sequencing of data packets, ensuring reliable communication between devices.

A device that connects two or more network segments and filters traffic between them. It operates at Layer 2 of the OSI model, examining MAC addresses to determine which segment a data frame belongs to.

A device that converts digital signals into analog signals and vice versa, enabling communication over telephone lines. It is essential for connecting computers to the internet through traditional phone lines.

A technique used for secure communication over the internet. It encrypts data packets, ensuring confidentiality and integrity during transmission. It is commonly used for websites and online transactions.

A network that connects devices within a limited geographical area, typically a building or a small campus. It is characterized by high bandwidth and close proximity of devices.

The process of connecting different networks to facilitate data exchange. It involves integrating various technologies, protocols, and devices to create a cohesive and functional network infrastructure.

A technology that allows you to create logically segmented networks within a physical network. It separates devices into different groups, enhancing security and improving network efficiency.

A device that assigns IP addresses to devices in a network. It automates the process, reducing manual configuration and ensuring efficient network addressing.

A type of cable used for high-speed data transmission in networks. It utilizes light pulses to transmit data, offering faster speeds, longer distances, and greater resistance to interference.

A device that forwards data packets between different networks based on IP addresses. It operates at Layer 3 of the OSI model, routing traffic to the correct destination.

A protocol used to send and receive emails. It handles the transfer of email messages from sender to recipient, ensuring reliable delivery.

A network that connects devices over long distances, typically spanning cities, countries, or even continents. It uses a variety of technologies, such as satellite, microwave, or fiber optic cables.

A network topology that combines elements of different network structures. It provides flexibility, reliability, and scalability, enabling network administrators to optimize performance for specific needs.

A device that filters and controls incoming and outgoing network traffic, acting as a security barrier. It helps prevent unauthorized access, protect against cyber threats, and ensure network stability.

The process of routing data packets through the best possible path between networks. It involves selecting the most efficient route based on factors such as traffic load, network distance, and network availability.

A unique identifier assigned to each device on a network. It allows networks to distinguish individual devices and facilitate communication between them.

A security mechanism that monitors network traffic for suspicious activities and potential threats. It alerts network administrators to possible attacks but doesn't actively block them.

A device that connects multiple devices within a single local area network (LAN) and forwards data frames between them based on their MAC addresses. It offers improved performance compared to hubs.

The maximum amount of data that can be transmitted over a network link in a given time. It is typically measured in bits per second (bps) and determines how much data can flow through a network.

A type of network device that broadcasts data to all connected devices. It simply forwards incoming data to every port, leading to potential collisions and reduced network efficiency.

A protocol used for secure file transfer over the internet. It encrypts data and protects it from unauthorized access during transmission, ensuring secure data exchange.

A technology used for secure communication over the internet, commonly used for websites and applications. It encrypts data packets, ensuring confidentiality and integrity of online transactions.

A protocol used to transfer files between computers over the internet. It is not secure as data is transmitted in plain text, making it vulnerable to interception.

A device that provides wireless connectivity to devices within a network. It acts as a bridge between wired and wireless networks, making it possible for devices to connect without cables.

A technique used to hide a device's true IP address behind another IP address. It is used in home networks and other private networks to share a single public IP address among multiple devices.

A technology that allows devices to communicate with each other directly without the need for a central server. It creates a temporary connection between devices, enabling data exchange over short distances.

A technology that allows devices to communicate with each other directly through radio waves. It enables communication over longer distances than Bluetooth and is commonly used for internet access and network connectivity.

The process of distributing incoming network traffic evenly across multiple servers or paths, improving performance and reliability. It prevents overload of individual servers and ensures optimal resource utilization.

A type of network device that acts as a gateway, connecting different types of networks and routing data between them. It translates addresses and protocols, enabling seamless communication across dissimilar networks.

A type of network device that operates at Layer 2 of the OSI model. It connects devices within the same network and forwards frames based on their MAC addresses.

A type of network device that operates at Layer 3 of the OSI model. It forwards data packets between different networks, routing traffic based on IP addresses.

A security measure that creates a virtual tunnel, encrypting data transmitted over the internet. It enhances privacy and security, allowing users to access private networks securely over a public network.

A protocol used for secure communication over the internet. It encrypts data packets, ensuring confidentiality and integrity during transmission.

A set of rules and procedures that govern how data is transmitted over a network. It defines the format, encoding, and sequencing of data packets, ensuring reliable communication between devices.
