Networking hubs are one of the oldest types of networking equipment and were widely used in the early days of computer networking. While they have been largely replaced by switches in modern networks, they are still used in certain applications. In this article, we’ll cover everything you need to know about networking hubs, including their functions, types, features, and key considerations when setting up and maintaining a hub.
Functions of Networking Hubs
Repeater – Hubs act as signal repeaters, regenerating signals and retransmitting them to all other devices on the network.
Broadcast – Hubs broadcast data to all devices on the network, which can lead to unnecessary traffic and reduced network performance.
Security – Hubs do not provide any security features and are vulnerable to unauthorized access.
Types of Networking Hubs
Passive Hubs – Passive hubs are the simplest type of hub and are used to simply regenerate signals.
Active Hubs – Active hubs are more advanced than passive hubs, and can amplify signals to extend the reach of a network.
Features of Networking Hubs
Port Speed – Port speed refers to the maximum speed at which data can be transmitted through the hub’s ports.
Number of Ports – The number of ports on a hub determines how many devices can be connected to the network.
Setting up a Networking Hub
Connection Types – Hubs can be connected to other devices using different types of connections, including copper and fiber.
IP Addressing – Hubs do not require IP addresses to function on a network.
Network Security
Hubs do not provide any security features and are vulnerable to unauthorized access.
Hub Troubleshooting
Resetting a Hub – Resetting a hub can help fix common problems, such as slow performance or dropped connections.
Checking Connections – Checking the physical connections on a hub can help diagnose connectivity issues.
Considerations for Choosing a Hub
Network Size – The size of your network should be taken into account when choosing a hub, as larger networks may require more ports and higher port speeds.
Network Traffic – The amount and type of network traffic on your network should also be considered when choosing a hub, as some hubs may be better suited for high-traffic networks.
Budget – Hubs are generally less expensive than switches, so they may be a good option for small networks with low traffic.
Popular Networking Hub Brands
D-Link – D-Link is a popular networking equipment manufacturer, and produces a range of hubs for home and small office use.
TP-Link – TP-Link is a budget-friendly networking equipment manufacturer that produces a range of hubs for home and small office use.
Upcoming Hub Technologies
There are no upcoming hub technologies, as hubs have largely been replaced by switches in modern networks.
In conclusion, networking hubs were once a common type of networking equipment, but have largely been replaced by switches in modern networks. While they are still used in certain applications, such as in testing or troubleshooting scenarios, switches are generally a better option for building and maintaining computer networks. Understanding the functions, types, features, and considerations for setting up and maintaining a hub can help you make informed decisions about your networking equipment and ensure that your network runs smoothly and efficiently.
