I'll see if I can give some somewhat vague answers to help you get started with them..

Differences between:
1) Data loss and data corruption
- These are completely different, you can't compare them. Data loss means that some of the data was lost, Data corruption means that some of the data had become corrupted. (Like the difference between not receiving a package (through conventional mail), and getting a damaged package)
2)centralized and distributed network configurations
- Centralized means that one (or a few) computers are in charge, distributed means that all peers are the "servers"
3)routers ,hubs and bridges
- hubs: allow multiple computers to be networked. Iirc, all they do is bounce all incoming data out on all connections (actually, newer ones are more intelligent, I think)
Bridge: allows users of one network to use another network through a server connected to both. The most common example is plugging a laptop into a LAN and using the wireless card to create a wireless network
Router: Routes packets, it's in charge of DHCP and stuff. Most routers also act as a bridge (connects internal network to the Internet), and a hub

The definition of a router has become muddied by the consumer products now sold as routers. This Wikipedia page might be useful to get started from; it tries to differentiate between the terms based on the layer of the OSI model that the device is aware of: http://en.wikipedia.org/wiki/Network_switch
