Router Components

1. Motherboard: - It is a main board of router. All the devices (internal) are connected with it.
   
   
   
2. Microprocessor: - This devices help router to process data communication and perform its task.
   
   

Interface: - Router has many interfaces.

Console Port: - By this port we can configure router.

Auxiliary Port: - This port is used for remote configuration of router.

Serial Port: - This port is used for serial connectivity.

Ethernet Port: - This is used for LAN connection.

Fast Ethernet Port: - This port is used for 100 base LAN connectivity.

Reset Hole: - From reset hole we can restore factory default setting.

3. Ram: - Ram is used when the data is processing.
   
   
4. NVRAM: - In a router Non volatile ram is used for permanent storage.
   
   
5. Flash Memory: - This memory stores the entire configuration while running.

Networking Devices

Hub: - Hub is a device which is used mainly for computer networking. It communicates data within systems. I t is a half duplex device which work on layer one.

Switch: - Switch is a intelligent device with communicates data between system and network which work on layer 2. It is a Full Duplex as well as Half Duplex devices. Switch terminate broadcast domain and minimized collision domain.

Bridge: - Bridge is a device which is used to connect different network topology. It works on layer 2.

Repeater: - Repeater is a device which is used to regenerate singles. This device work on layer 1. There are two types of repeater.

1. Active Repeater
2. Passive Repeater

 

Router: - Router is a device which is used for connecting multiple WAN networks. Router works on layer 3. The main works of router are routing, filtering (packet and data), security, connection or terminating collision domain.
