Wireless

Definition:
Wireless networks are networks that use wireless technology to connect devices and enable communication without the need for physical cables. These networks use radio waves, infrared, or other wireless signals to transmit data between devices.

Key Features:

1. No Wires: Wireless networks eliminate the need for physical cables, offering more mobility and flexibility.
2. Multiple Technologies: They use various wireless technologies such as Wi-Fi, Bluetooth, and cellular networks (e.g., 4G/5G).
3. Mobility: Devices can be connected and communicate freely within the range of the network without being tethered to a fixed location.
4. Range: The range of wireless networks depends on the technology used (Wi-Fi typically covers up to 100 meters, while cellular networks can cover large areas).

Core Components:

• Access Points (APs): Devices that allow wireless devices to connect to the network (especially in Wi-Fi networks).
• Routers: Devices that route traffic between the wireless network and external networks, like the internet.
• Wireless Devices: Laptops, smartphones, tablets, printers, and other devices with built-in wireless capabilities.

Uses:

• Connecting devices to the internet without the need for Ethernet cables (e.g., Wi-Fi).
• Transmitting data between devices over short distances (e.g., Bluetooth).
• Enabling communication in mobile networks (e.g., 4G, 5G).

Example:
Using Wi-Fi at home or in a coffee shop to connect your phone or laptop to the internet without any cables.

Summary:
Wireless networks allow devices to communicate and access resources without physical connections, offering flexibility, mobility, and the convenience of connecting over radio waves or other wireless signals. Technologies like Wi-Fi, Bluetooth, and cellular networks are commonly used in these types of networks.
