Network hardware is an essential component of any computer network. It refers to the physical devices that connect computers and other devices to each other and to the Internet. Network hardware includes routers, switches, bridges, firewalls, and modems. Each of these devices plays a specific role in ensuring that data is transmitted and received correctly.
Routers are responsible for directing traffic between different networks. They use routing protocols to determine the best path for data to take. Switches connect devices within a single network. They learn the MAC addresses of the devices connected to them and forward data to the appropriate device.
Bridges are similar to switches, but they operate at a lower level of the network stack. They connect two or more networks that use the same protocol. Firewalls protect networks from unauthorized access. They inspect incoming and outgoing traffic and block any traffic that does not meet the security policy.
Network hardware provides a number of benefits, including:
