Fundamentals of Networking Quiz

A network covering a large geographical area, connecting multiple LANs across cities, regions, or countries. It uses public networks like the telephone system, leased lines, or satellites.

A specialized network dedicated to storage devices like disk arrays, tape libraries, and optical jukeboxes, making them appear as locally attached to servers.

A network of networks, a global system connecting billions of users worldwide. It uses the TCP/IP protocol and comprises millions of private, public, academic, business, and government networks.

A network connecting devices in a specific geographical area, often limited to a city or municipality. It acts as a bridge between multiple LANs within that area.

A local network connecting devices within a building or a small campus area. Typically owned by the building owner or tenant.

A network connecting devices within a limited area like a single room or building. Usually owned by the building owner.

A group of connected computers and devices that share resources and communicate with each other.

A network that connects devices close to a person's body, like a smartphone and tablet.

The sharing of resources like printers, scanners, and files among devices on a network.

The ability to communicate with others through email, video conferencing, and instant messaging.

The ability to access and manage data across multiple devices on a network.

The process of connecting multiple LANs to create a larger network, often used for connecting offices or branches of a company.

TCP (Transmission Control Protocol) is a communication protocol used for reliable data transfer between applications. It establishes a dedicated connection between two applications, ensuring that data is delivered in order and without loss.

UDP (User Datagram Protocol) is a simpler and faster communication protocol than TCP. It provides less reliability, as data packets might be lost or arrive out of order.

IP (Internet Protocol) is responsible for addressing and routing data packets across a network. It is a connectionless protocol, meaning it does not establish a dedicated connection between computers.

ICMP (Internet Control Message Protocol) is used for sending error messages and diagnostic information across the network. It allows devices to communicate about network issues or failures.

DHCP (Dynamic Host Configuration Protocol) is a protocol that automatically assigns IP addresses to devices on a network. This simplifies network administration and eliminates manual configuration.

A full-duplex communication allows data to be sent and received simultaneously between two parties.

IP routers are devices that forward data packets across a network based on their destination address. They ensure that packets reach their intended recipients efficiently.

TCP and IP work together to enable reliable communication over the internet. TCP handles the application-level communication, while IP handles the addressing and routing of data packets.

A protocol used to send web requests from a browser (client) to a web server and receive web content back.

A secure version of HTTP that encrypts communication between web browsers and servers, ensuring safe transmission of sensitive data like credit card information.

This protocol handles sending and receiving emails. It allows you to send emails from your email client to a server.

Allows SMTP to transfer various media types like audio, video, and images within emails.

This protocol helps you access emails stored on a server as if they were on your computer, letting you manage them directly.

Allows you to download emails from a server onto your personal computer.

Used to transfer files between computers across networks.

This protocol ensures that all connected devices in a network share the same time.

A unique numerical identifier assigned to every computer on a network, allowing them to communicate with each other. It consists of four numbers separated by dots, ranging from 0 to 255.

A domain name is a human-readable name for a website, like "w3schools.com". It is translated into an IP address by a Domain Name Server (DNS) for computers to access the website.

DNS servers translate domain names into IP addresses, allowing computers to locate and access websites. They act as a directory for all domain names on the internet.

A single computer byte is 8 bits. TCP/IP uses 32 bits, which is equivalent to 4 bytes, to address a computer.

TCP/IP is a suite of communication protocols used to connect computers on the internet. It consists of various protocols like TCP, IP, HTTP, and others, each responsible for specific functions in data transmission.

A high-speed internet connection using coaxial cables, offering speeds of up to 100 Mbit/s. Supports multiple services like data and voice.

An internet connection using telephone lines, with faster download speeds than upload speeds.

A connection type that uses telephone lines for high-speed internet with equal download and upload speeds. Not commonly used because it's not standardized.

A very high-speed DSL technology offering speeds from 4 to 100 Mbit/s.

An older internet connection using voice telephone lines, offering limited speeds of up to 56 kb/s. Slow and outdated.

A high-speed connection using fiber optic cables, providing high-speed internet, video, and voice services with up to 1 Gbit/s speeds.

A satellite-based internet connection offering limited speeds. Ideal for remote locations but suffers from higher latency than terrestrial connections.

A network system designed for voice and data, using dedicated lines and channels. Commonly used for connecting phone systems.

A cellular technology that uses mobile towers (cells) to provide internet access.

A wireless technology that uses microwave frequencies for high-speed internet access. It can be fixed or mobile, covering a broader range than Wi-Fi.
