What Devices are Used in Networking?

The networking sector utilizes multiple types of equipment to facilitate seamless communication and data exchange among multiple connected devices. In this article, we will examine some of the principal networking devices used, including Cisco Meraki Systems Manager.

The most basic type of networking device is the Network Interface Card (NIC). Every device on a network, from computers to printers, has an NIC that enables it to connect to the network and communicate with other devices on the network.

Network cables, including Ethernet cables and fiber optic cables, physically connect devices within a network. Different types of cables offer different data transfer speeds, and the right type depends on the specific requirements of the network.

Switches are networking devices that connect multiple devices, such as computers, printers, and servers, within a building or campus. They provide a way for information to flow from one device to another within the network. Switches ensure that data goes from its source to its correct destination.

Routers are devices that connect two or more logical subnets, which do not necessarily map one-to-one to the physical interfaces of the router. The functions of a router include determining the best path for data packets to travel and directing them to their destinations. Routers can connect a home or business network to the internet.

Wireless Access Points (WAPs) are used to connect wireless devices to a network. They send and receive data via radio waves and serve as the central transmitter and receiver of WLAN radio signals.

Hubs serve as a common connection point for devices on a network. They use a protocol called Ethernet to enable communication between connected devices. When a data packet arrives at one port, it is copied and sent to all other ports so that all segments of the LAN can access it.

Firewalls serve as security devices on a network. They monitor incoming and outgoing network traffic and decide whether to allow or block specific traffic based on predefined security rules.

Network bridges are used to divide larger networks into smaller sections. They act like a switch by forwarding data between networks and preventing unnecessary traffic.

Network gateways, as the name suggests, act as an entry and exit point for a network as they control data traffic flowing in and out of the network.

Terminal servers let you connect devices with an RS-232, RS-422, or RS-485 serial interface to a local area network (LAN). Because each device gets its own dedicated session on the terminal server, each one operates independently of the others.

At last, one of the advanced network devices plays a significant role – Cisco Meraki Systems Manager. It provides over-the-air centralized management, diagnostics, and monitoring for all networks. This network management system simplifies the task and enables remote control of devices ensuring all devices are secure and under administrative control. It also includes wireless functionality control that ensures devices on the network behave within predefined parameters.

In conclusion, from the smallest home networks to the largest enterprise networks, these devices each play their vital role in ensuring smooth and secure network communication. Technological advancements continue to add new devices and methods to the repertoire, further enhancing networking’s capabilities and scope.
