A worldwide system of interconnected computer networks using standardized protocols (TCP/IP) to connect billions of users.

A collection of devices (computers, servers, etc.) connected together to share resources and information.

A set of rules that define how devices communicate within a network, ensuring they understand each other.

To access and utilize resources provided by other devices connected to the same network.

Each device on a network has a unique address, like a postal code, allowing data to be delivered correctly.

A set of connected documents linked to each other by clickable links.

The transfer of data, like images and documents, between devices on a network. Requires a protocol.

Computer networks are vulnerable to security threats because of the interconnected nature of devices.

Sharing computing resources like programs and data between computers connected on a network.

A computer network that allows controlled access to specific users from outside the organization.

A network used within a single organization, accessible only to authorized members.

A network that connects computers and devices within a limited geographical area, like a home, office, or school.

The act of sending computer viruses or worms to devices on a network, or preventing access to a network.

Sharing program files among computers connected to a network.

Sharing data files between computers on a network, allowing access to large databases.

Providing services like data processing or file storage to computers on a network.

A network used to transmit messages between people, often for communication and collaboration.

A network used to spread computing workload between multiple computers, improving performance and efficiency.

A tool released in 1992 that enabled researchers to retrieve data from various locations, marking an early step in web technology.

A web browser developed in 1993 by Marc Andreesen, a key event in the World Wide Web's evolution.

A protocol that allows users to transfer files between computers over a network, with features like anonymous access and file sharing.

FTP's main goals include making it easy to share files, ensuring reliable transfer, and enabling users to interact with remote computers.

A telecommunication utility software that allows you to connect to and use a remote computer over a network.

Telnet involves sending commands from your computer to your ISP, which then forwards them to the remote computer you're accessing.

Telnet can be used to access your own account from a different location, allowing you to check email or manage your account while traveling.

A computer network spanning a large geographical area, like a city, country, or even continents. It uses various communication channels like phone lines, cables, and wireless signals.

A network built by a company to connect its different locations, like offices, factories, and stores, enabling them to share resources.

A network that uses public infrastructure like the internet to create secure connections between devices. It's like a tunnel, but for data.

The arrangement of how devices are connected in a network. It's about their logical relationships, not their physical placement.

A network topology where all devices connect directly to a central hub. It's like everyone speaking to the hub, and the hub distributing info.

A network topology where devices are connected in a linear chain. It's like a single line of communication.

A network topology where devices are connected in a ring shape, with data flowing in one direction.

A network topology where there are multiple paths for data to flow, making it more resilient to failures. It's like having multiple roads to reach a destination.

Networks that transmit data using electrical signals, representing data as 0s and 1s, for greater accuracy and speed.

Networks that transmit data using analog signals, representing data as continuous waves, for a wider range of frequencies.

A type of network where all devices are connected to a central hub. Imagine a central point with spokes radiating outwards, connecting all devices.

A type of network where devices are connected in a circular fashion. Information travels in one direction around the circle.

A network where every device is directly connected to every other device. Data can travel on multiple paths, creating redundancy.

A network where devices are connected to an arbitrary number of neighbors. Data can travel through multiple paths.

A type of network where all devices are connected to a shared cable or medium. Info travels along the cable.

A standard or set of rules that network devices use to communicate. Ensures devices understand each other.

The early network that was developed by the U.S. Defense Department to withstand a nuclear attack. It was the precursor to the modern internet.

A type of device that was used to connect to a LAN. It is like a desktop computer.

The early network protocol used on ARPANET. It was replaced by TCP/IP.
