Network Hub

Definition of Network Hub

A network hub is a basic networking device that connects multiple devices in a local area network (LAN). It operates at the physical layer of the OSI model, which means it simply forwards data packets to all devices connected to it without any intelligence or awareness of the content of the packets.

Origin of Network Hub

The concept of network hubs dates back to the early days of computer networking when Ethernet technology was emerging. Hubs were initially developed to facilitate communication between devices within a small network. They served as a central point for connecting computers, printers, and other networked devices, allowing them to share resources and communicate with each other.

Practical Application of Network Hub

One practical application of a network hub is in small office or home office (SOHO) environments where simplicity and cost-effectiveness are prioritized over advanced network management features. Hubs are often used to establish basic LAN connectivity for sharing internet access, printers, and files among a few devices within a limited area.

Benefits of Network Hub

Cost-Effective Connectivity: Network hubs are typically more affordable than other networking devices such as switches or routers, making them an attractive option for budget-conscious users.

Ease of Use: Setting up a network hub is straightforward and requires minimal configuration. Users can simply plug in their devices, and the hub will automatically handle the connections, eliminating the need for complex network setup procedures.

Compatibility: Network hubs are compatible with a wide range of devices, including computers, printers, scanners, and other peripherals. This versatility makes them suitable for various networking scenarios, from small home networks to larger office environments.


No, network hubs are designed for wired connections only. For wireless networking, you would need a wireless access point or router.

While switches and routers offer more advanced features and better performance, network hubs still have their place in certain scenarios, especially where simplicity and cost-effectiveness are paramount.

Technically, yes, you can daisy-chain multiple hubs together, but it's not recommended as it can lead to network congestion and performance issues. It's better to use a switch for expanding network connectivity.
