Hello,

When you buy a switch or router, it comes with some default interfaces and some empty slots.

Default interfaces are usually ethernet interfaces; however, router or switch support more different kinds of interfaces. You can order and buy those interfaces depending on your needs. New interfaces comes in the forms of modules can be put inside those empty slots. Suppose you need to etablish a WAN connection between two different locations. So you need to buy a WAN module. It is like buying a ethernet card for your computer. Or you need to connect fiber cables to your router, so you need to buy a module with fiber interfaces.

There are two types of module and also two different slots on routers. Smaller slots are for WIC and bigger for NM (Network module)

1-Network module(your question).

This is a bigger module that can hold a variaty of ports and also some NM modules and some WICs. These module usually can be inserted in bigger routers.

2-

WIC is smaller card that can be inserted in a router dirrectly or in some NM card.

WIC and NM are a little old and today HWIC and NME are mostly used.

Please check the link below to check different kinds of module for router 2800. Take a look at the modules with the prefix of NM, NME, WIC, HWIC.

If you're asking about hardware modules that are inserted into a network device, it allows the network device to provide different capabilities without the need to swap the whole device and/or without provide many features that would otherwise not be needed.

For instance, on a small ISR, a network module might allows for the addition of Ethernet ports, special WAN media, or it might support hardware acceleration of some special feature.
