Latest Internet Networking Devices with Description and Images
This article explains the most commonly used internet networking devices, their functions.
1. Gateway
A gateway connects your internal home or office network to the wider internet. It translates data between different networks, such as a local area network (LAN) and a wide area network (WAN). Modern gateways often combine modem and router functions.
2. Router
A router directs data traffic between networks, especially between your devices and the internet. Modern routers support Wi-Fi 6, firewall security, parental controls, and advanced encryption.
3. Network Switch
A network switch connects multiple wired devices within a local area network (LAN). It forwards data only to the intended device, improving network efficiency and performance.
4. Modem
A modem (Modulator-Demodulator) converts signals from your internet service provider (DSL, cable, or fiber) into digital signals your devices can use.
5. Wireless Access Point (AP)
A wireless access point extends Wi-Fi coverage by connecting to a wired network and providing wireless connectivity to devices.
6. Network Hub
A hub is an older networking device that broadcasts incoming data to all connected devices. It has largely been replaced by switches in modern networks.
7. Bridge
A bridge connects different network segments and filters traffic to reduce unnecessary data transfer.
8. Network Interface Card (NIC)
A Network Interface Card (NIC) is hardware installed in devices such as computers or servers to enable wired or wireless network connectivity.
