Types of network devices?

1.Hub
2.Router
3.Switch
4.Bridge

Why we need network devices for example if you are using modem, will connect maximum four device like pc or laptop. in case 50 pc's are your requirements then we want to use router or switch these devices are share signal equally to connected system. Example 8mbps speed of your connection will share equally to systems via these switch, router. But each network device have specific functions.

1.Hub is a central connecting device in star topology (early days we used this hub) two types of hub 1. Passive hub 2. Active hub

1. Passive hub is network device simply connect to modem then share signal, traffic equally.

2. Active hub also called as multiport repeater it will regenerate data then share signal. ( for example weak signal may drop the data when travel long distance in order to avoid this active hub regenerate signal and make strong then share signal, data ) active hub need electricity power to regenerate signal.
