Study Notes

Wi-Fi Protected Access (WPA)

Primary purpose: Provide wireless security by encrypting data transmitted over a wireless network.

Subnetting

Main advantage: Allows for more efficient use of IP addresses, better organization of networks, and improved network performance.

Network Segmentation

Primary goal: Divide a network into smaller, isolated segments to restrict access and reduce the attack surface, thus enhancing network security.

Fog Computing

Main characteristic: Brings computation and data processing closer to the IoT devices, reducing latency and improving real-time processing capabilities.

Software-Defined Networking (SDN)

Primary benefit: Enables centralized network management, programmability, and scalability, leading to a more agile and efficient network architecture.
