What device is designed to filter and transfer data packets between dissimilar types of computer networks?

Networking devices have different roles to play in a computer network.

To build a strong computer network, you need to understand the devices that comprise it. Tech enthusiasts call these components ‘network devices’, also known as ‘networking devices’.

If you have a robust internet setup, this may be something you are already familiar with. Nevertheless, it won’t hurt to recall the basics and learn what networking devices are.

The more you know about this hardware, the better – and you are about to find out why. Read ahead!

Networking Devices Explained

Networking devices are used for communication between hardware on a computer network. In a computer network, they are mainly used for transmitting and receiving data.

They link computers, printers, faxes and other devices to the network. They may be on an intranetwork or internetwork.

Each device plays an important role in the networks functionality. Moreover, they work for different purposes in various segments.

A networking device is also called network hardware.

Types of Networking Devices

There are different types of network devices used in a computer network, and these include:

• Network Hub
• Network Switch
• Modem
• Network Router
• Bridge
• Repeater
• Gateway
• Access Point

1. Network Hub

Network hubs connect multiple computer networking devices or network hosts together. A hub amplifies signals that deteriorate after travelling long-distance over connecting cables.

Further, it connects LAN components with identical protocols. Ideal for data transferring; the data is sent via packets on a computer network.

But due to its working mechanism, a network hub is not secure and safe. Copying the data packets on interfaces makes it slower and more congested.

This led to the use of a network switch.

2. Network Switch

Like the hub, a network switch also works for a LAN but even better! It is a multiport device that helps improve network efficiency.

The switch maintains limited routing information about nodes in the internal network. It allows connections to systems like hubs or routers.

Generally, switches can read the hardware addresses of incoming packets. Then, they will transmit the packets to the appropriate destination.

Even better, they can also improve network security. For one, virtual circuits are more difficult to examine with network monitors.

You can think of a network switch as a device that has the best capabilities of hubs and routers combined.

3. Modem

Modems are used to send digital signals over analogue telephone lines. Standing for modulator + demodulator; they ‘modulate’ and ‘demodulate’ the signal between the two.

The modem converts digital signals into analogue signals of different frequencies. Then, transmitted to a modem at the receiving location.

The receiving modem performs the reverse transformation. At the same time, it provides a digital output to a device connected to a modem, usually a computer.

The digital data is transferred to or from the modem over a serial line through an RS-232.

4. Network Router

The network router handles routing traffic from one network to another. It helps transmit packets by charting a path through interconnected networking devices. Plus, using different network topologies.

Routers are general-purpose devices that interconnect two or more heterogeneous networks. They are dedicated to special-purpose computers with separate input and output network interfaces.

They are intelligent components storing information about the networks they are connected to. Routers establish communication by maintaining tables about destinations and local connections.

You can think of a router as a highway patrol who diverts network traffic in various directions.

5. Bridge

As the name suggests, a bridge is used to connect two or more hosts or network segments together. Its basic role in network architecture is storing and forwarding frames.

This is between the different segments that the bridge connects. If a router connects two types of different networks, the bridge connects two subnetworks as a part of the same network.

Bridges use hardware Media Access Control (MAC) addresses for transferring frames. By looking at the MAC address from the connected devices, they can forward the data or block it from crossing.

Bridges can also be used to connect two physical LANs into a larger logical LAN. Like network hubs, they can be either simple or multiple ports.

6. Repeater

A repeater amplifies the signal it receives. A device that receives a signal and retransmits it at a higher level or higher power.

This way, the signal can cover longer distances (over 100 metres), than standard LAN cables. Repeaters also work on the Physical layer.

7. Gateway

A gateway performs at the session & transport layers in the OSI model. It offers conversion between networking technologies like OSI (Open System Interconnection) & TCP/IP.

Because of this, gateways connect two or more autonomous networks. With its own routing algorithms, protocols, and topology, including:

• Domain name service
• Network administration procedures and policies

Moreover, gateways perform all the functions of routers. In fact, a router with added translation functionality is a gateway. The translation between different network technologies is called a protocol converter.

8. Access Point

An Access Point (AP) involves either a wired or wireless connection, but it is usually a wireless device. It works at the second OSI layer, a.k.a. the Data Link layer.

Plus, it can operate as a bridge connecting a standard wired network to wireless devices. Or as a router passing data transmissions from one access point to another.

In general, an AP is a separate network device with a built-in antenna, transmitter and adapter. It uses the wireless infrastructure network mode to provide a connection point between WLANs and a wired Ethernet LAN.

APs can also provide ports to increase the network’s size, firewall capabilities and DHCP service. DHCP stands for Dynamic Host Configuration Protocol.
