Hardware plays one of the most crucial roles when it comes to computer networking. Unlike other domains of information technology industry, networking is fully based on more hardware and less software. Let’s discuss briefly about the computer networking hardware found in regular computer networks.

Network Cards and Interface Devices

When it comes to computer networking hardware, there is no networking exist without the use of network interface cards or devices. The network card is the interface between the rest of the network and the computer linked through RJ45 cables. The network interface cards are available in different forms for different computers. As examples, PCI card variety is available for desktops, USB dongle form is available for any type of computer, and PCMCA card variety is available for laptops.

Network Cables

Network cables link the computers and the rest of the computer networking hardware. Network cables normally have a diversity depending on the type of the computer network. Although the copper coaxial cables are not in use any longer, the descendent, multi-core RJ45 cables are the widely used type. For high speed links and Internet backbones, fiber optic cables, fiber optic scope and borescope camera are used as they are capable of facilitating higher bandwidths.

Wired and Wireless Routers

Routers are the most primary devices when it comes to computer networking hardware. They link you with the rest of the globe and enable you to find the information on the Internet and in the local network. For various purposes and network types, there are several types of routers. The cost and the abilities of these routers vary depending on the purpose. When it comes to wireless routers, they are the latest addition to the class of computer networking hardware. Decrease of the mammoth wiring and users being able be mobile are two main rewards of wireless routers.

Hubs

Hubs behave the same way as routers but does not route your to the Internet or external networks located beyond your local area network. When it comes to connecting computers and network devices within a small, limited geographical area, hub is the ideal device. Hubs are normally less expensive compared to the rest of the computer networking hardware.

Switches

When a network is expected to be linked to an outside network, then switches deliver the greatest results out of all computer networking hardware. As an example, if two local area networks (LANs) are to be connected together, ordinarily a switch is used. Since most of the switches are programmable, you can use switches to specify how your network should behave when interface with external networks.
