A network is a collection of computers, servers, devices, or other nodes connected together to share resources, communicate, and exchange data. Networks can be categorized based on their geographic scope.Wireless networking, often referred to simply as "wireless," is a type of networking technology that allows devices to communicate without using physical cables. Wireless networks utilize electromagnetic waves, such as radio frequencies, to transmit data between devices. Networks can also be categorized based on their topology (physical or logical layout) and the technologies used for communication, such as Ethernet, Wi-Fi, and cellular networks.
1.Mobility: Wireless networks allow devices to connect and communicate without being tethered to a fixed location. Users can move freely within the coverage area of the wireless network while maintaining connectivity.
2.Roaming: Wireless networks support roaming, allowing devices to maintain connectivity while moving between different access points within the coverage area. This seamless handoff ensures uninterrupted connectivity for mobile users as they move throughout a building or campus.
3.Security: Wireless networks employ various security measures to protect against unauthorized access, data breaches, and other security threats. These measures may include encryption (e.g., WPA2, WPA3), authentication mechanisms (e.g., WPA2-Enterprise), MAC address filtering, firewalls, and intrusion detection/prevention systems.
4.Management and Monitoring: Wireless networks can be managed and monitored using centralized management tools, allowing administrators to configure settings, monitor performance, troubleshoot issues, and enforce security policies from a central location.
5.Speed and Performance: Modern wireless technologies, such as Wi-Fi 6 (802.11ax), offer high data transfer rates and improved performance compared to older standards. This enables faster download and upload speeds, reduced latency, and better support for bandwidth-intensive applications like streaming video and online gaming.
