Connecting Devices

Three Layer Switch
-Connects multiple devices to create a network
-Also acts as a router and provides users on the network with an internet connection
Fragmentation
Fragmentation is an important function of network layer in which gateways break up or divide larger packets into smaller ones called fragments. The two types of fragmentations are transparent fragmentation and non-transparent fragmentation.
-
-Transparent Fragmentation
This fragmentation is done when one network is made transparent to all other subsequent networks through which packet will pass. Whenever a large packet arrives at a gateway, it breaks a packet into smaller fragments.
-Non-Transparent Fragmentation
This fragmentation is done when one network is non-transparent to the subsequent networks through which a packet passes. Packet fragmented by a gateway of a network is not recombined by exit gateway of same network.
