A network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules A network hardware device that forwards data packets between computer networks
A unique numerical label assigned to each device connected to a network that uses the Internet Protocol for communication. The process of selecting the best path for data packets to travel from source to destination in a network.
A mechanism that prioritizes certain types of network traffic, ensuring higher performance for critical applications or services. The process of modifying the IP addresses in packets as they pass through a router, allowing multiple devices to share a single public IP address.
The distribution of network traffic across multiple devices or links to optimize resource utilization, maximize throughput, and minimize response time. A secure network connection that allows remote devices to access a private network by encrypting their data and tunneling it through the public internet.
