What Is WiFi And How Does It Work?
WiFi is a type of wireless networking technology that allows devices to connect to the internet or communicate with each other without the use of cables or wires. It works by transmitting data through radio waves at a specific frequency, typically 2.4 gigahertz (GHz) or 5 GHz. WiFi networks use a wireless router to transmit and receive data to and from devices, which are equipped with WiFi adapters.
When a device connects to a WiFi network, it sends a request to the router, which then authenticates the device and grants access to the network. The router then assigns an IP address to the device, allowing it to communicate with other devices on the network and access the internet. WiFi networks can be secured with passwords and encryption to prevent unauthorized access.
What Is LAN And How Does It Work?
LAN, or Local Area Network, is a type of computer network that connects devices within a limited geographical area, such as a home, office building, or campus. LANs use cables, typically Ethernet cables, to connect devices to a central hub or switch, which manages data transmission between devices. LANs can also be wireless, using WiFi technology to connect devices.
In a LAN, devices are connected to a central hub or switch, which acts as a bridge between devices. When a device sends data to another device on the network, the data is transmitted through the hub or switch, which directs it to the intended recipient. LANs can be used to share files, printers, and internet connections between devices, and can be secured with firewalls and access controls to prevent unauthorized access.
What Are The Differences Between WiFi And LAN?
The main difference between WiFi and LAN is the method of connection. WiFi is a wireless technology that uses radio waves to connect devices, while LAN is a wired technology that uses cables to connect devices. WiFi networks are typically more convenient and flexible, as devices can move freely within the network area without being physically connected. LANs, on the other hand, are typically faster and more secure, as data transmission is less susceptible to interference.
Another key difference between WiFi and LAN is the range of coverage. WiFi networks can cover a wider area, typically up to several hundred feet, while LANs are limited to the length of the cables used to connect devices. However, LANs can be extended using repeaters or switches, allowing them to cover larger areas.
What Are The Advantages Of WiFi?
