Common network devices include: Routers: connect different networks and forward data packets. Switch: Connects devices on the same network and forwards data efficiently. Bridge: Connects multiple LAN segments, allowing communication. Modem: Connects your computer to the Internet or other networks. Hub: Connect devices through broadcasting. Firewall: Monitor data traffic and block unauthorized access. Network card: The physical connection interface between the computer and the network.

What are the common network devices?

Common network equipment

In the modern network world, various network devices play a vital role Function, realizing the smooth progress of network connection, data transmission and communication. Here are some of the most common types of network devices:

routers
Routers connect different networks or subnets, forwarding packets from one network to another. Routers use routing tables to determine where to forward packets so that data can travel over the Internet.

Switch
A switch connects multiple devices on the same network, such as computers, printers, and servers. Switches forward packets in a fast and efficient manner by identifying the MAC addresses of connected devices.

Bridge
A bridge connects two or more LAN (Local Area Network) segments, allowing them to communicate with each other. Bridges create larger networks by filtering and forwarding packets.

Modem
A modem connects your computer to the Internet or other networks. They convert digital signals from computers into analog signals for transmission over telephone or cable lines. At the other end, the modem modulates the analog signal back into a digital signal, allowing the computer to access the network.

Hub
A hub connects multiple devices to form a star topology. The hub sends packets in a broadcast manner, that is, to all connected devices.

Firewall
A firewall is a network security device designed to monitor and control data traffic entering and leaving a network. Firewalls block unauthorized access and malicious traffic through the use of firewall rules and access control lists (ACLs).

Network Interface Card (Network Card)
A network card is a hardware device inside or outside the computer that allows the computer to connect to a network. It provides the physical connection needed for computers to communicate with the network.

These devices together form the infrastructure of modern networks, providing the necessary connection and transmission functions for our daily communications, information access, and entertainment.
