Networking hardware is the building block of a computer network. Below are the basic hardware components.
Network Interface Controllers
A network interface controller (NIC) is a circuit board that enables a computer to connect to a network. NIC provides the computers with the ability to access the transmission media.
Repeaters and Hubs
A network repeater regenerates incoming signals so that they can travel long distances safely. A hub is a multiport repeater that is used to connect segments of a local area network.
Bridges
A network bridge connects multiple network segments to create a single aggregate network. The most common types of bridges are local, remote, and wireless.
Switches
A network switch is a hardware component that centralizes communications among multiple devices within a local area network. In most of the business networks, switches are used to connect computers, printers, and servers within a building.
Routers
A router connects multiple computer networks by using wired or wireless connections. Routers forward data packets among networks by using the routing information inside these packages.
Modems
A modem is a device that serves as a bridge between a local network and the Internet. The primary function of a modem is to convert between analog and digital data in real time.
Firewalls
A firewall is a protective system that lies between a computer network and the Internet. The main goal of a firewall is to control network security and access. Although we present firewalls under networking hardware, they can also be software entities.
