Here are 7 key pieces of network hardware:
Each of these devices plays a crucial role in setting up and maintaining a network, ensuring communication and security between devices.
- Router: This device connects different networks, such as a local network (LAN) to the internet (WAN). It routes data between these networks, making sure it reaches the correct destination.
- Switch: A switch connects multiple devices within the same network (like computers or printers). It works by forwarding data to the correct device based on its MAC address.
- Hub: A hub is a basic networking device that connects multiple devices. Unlike a switch, it sends data to all connected devices, which can create unnecessary traffic.
- Modem: A modem (short for "modulator-demodulator") connects your network to the internet via your ISP (Internet Service Provider). It converts digital signals from the computer into analog signals for transmission over phone lines or cable.
- Access Point (AP): An access point allows wireless devices (like laptops or smartphones) to connect to a wired network. It's a bridge between the wireless and wired network.
- Firewall: A firewall is a security device that monitors and controls incoming and outgoing network traffic. It helps prevent unauthorized access to or from a private network.
- Network Interface Card (NIC): This is the hardware that allows a device (such as a computer or printer) to connect to a network, either via Ethernet (wired) or Wi-Fi (wireless).
