Hub Definition
A hub is a network device that connects multiple devices on a single network segment, allowing them to communicate with each other. It acts as a central point of connection, facilitating data transmission between devices.
Types of hubs include:
- Passive hubs: These hubs simply relay data signals without any amplification or regeneration.
- Active hubs: These hubs amplify and regenerate data signals, ensuring reliable transmission over longer distances.
- Intelligent hubs: These hubs offer additional features such as traffic monitoring, error detection, and port management.
Hub Characteristics, Hub def
Key characteristics of hubs include:
- Simple and inexpensive
- Plug-and-play functionality
- Supports multiple devices
- Limited bandwidth capacity
- No collision detection or error correction
Common hub configurations include:
- Star topology: Hub is at the center, with devices connected to it.
- Bus topology: Devices are connected to a single cable, with the hub at one end.
Hub Applications
Hubs are used in various applications, such as:
- Small office or home networks (SOHO)
- Temporary or ad-hoc networks
