Networking Concepts and Global Edition Contributors

The internet is a global network of interconnected computers and devices that communicate using specific rules called protocols.

The internet is a collection of networks, routers, and servers working together to allow data transfer between devices.

The internet provides services like web browsing, email, and file sharing by allowing devices to access resources on other computers.

A protocol is a set of rules and standards that govern how devices communicate on the internet.

A recent paradigm shift in networking where control and data planes are separated, allowing for more programmable and flexible network management.

The part of the network layer responsible for handling data forwarding and routing decisions.

The part of the network layer focused on managing and configuring the network infrastructure.

A popular open-source scripting language used in many networking tools and applications.

The process of managing and maintaining a network infrastructure, including tasks such as configuration, monitoring, and troubleshooting.

A protocol designed for transferring files over a network.

A method for distributing data across multiple servers to improve performance and reliability.

A popular service for streaming videos online with features like content recommendation and personalized user experience.

A method for detecting errors in data transmission by adding a single bit to each data unit (e.g., byte) that represents the parity (odd or even) of the number of 1s in the data.

A technique commonly used for error detection in data transmission. It involves calculating a checksum value based on the data and adding it to the transmitted data.

A powerful error detection and correction technique (EDC) that uses a unique mathematical calculation to generate a checksum for each data block. It's commonly used in networking and storage devices.

A method for sharing a communication channel among multiple users. It's commonly used in wireless networks.

A type of multiple access protocol where users are assigned specific time slots or frequencies for data transmission.

A type of multiple access protocol where users can transmit data whenever they want, with the risk of collisions between their data packets.

A network that uses switches to connect multiple devices.

A protocol used to resolve IP addresses to physical MAC addresses for devices on a local network.

Devices that connect to the internet, like laptops, smartphones, tablets, TVs, and even cars.

A group of interconnected computers and devices using rules called protocols.

Specialized devices that direct traffic across the internet.

The set of rules that devices on the internet follow to communicate effectively.

The physical and logical pathways used to connect devices on the internet.

The process of breaking data down into smaller packets and sending them over the internet.

A network that connects a larger geographical area, even across countries.

A network that connects devices in a smaller area, such as a building or home.

This cryptography technique uses the same key for both encryption and decryption.

A cryptographic method that uses two separate keys, one for encryption and another for decryption. These keys are mathematically linked but one cannot be derived from the other.

A function that takes an arbitrary-length message and produces a fixed-length output called a hash value (or digest). It should be computationally infeasible to find two messages with the same hash value.

A code generated by a cryptographic hash function to ensure the authenticity and integrity of a message. It's calculated over the message and a secret key, ensuring that any change to the message will invalidate the MAC.

A cryptographic method that uses a private key to sign a message, and a corresponding public key to verify the signature. This ensures authenticity, integrity, and non-repudiation.

A process that verifies the identity of the communicating parties. In secure communication systems, this step ensures the authenticity of the participants and prevents impersonation.

A method to secure email communication by encrypting the message content and adding digital signatures. This ensures confidentiality, integrity, and non-repudiation.

Provides end-to-end secure communication for email, using cryptography and digital signatures.

A protocol used to secure communications over TCP/IP networks. It uses encryption and digital certificates to establish a secure connection between a client and a server.

A network layer security protocol (IPsec) used to build VPNs, establishing secure connections for communication between two devices over a public network.
