Hi Suryakant,
uplink will forward normal traffic to other switches or any devices.
Normally the interface speed used for uplinks will be high.
Trunk link will be used for carrying vlan traffic to other switches or any other devices.
If you are using vlans on switches and you want that vlan traffic to be forwarded to other switches then you have to configure trunk links.
If you are not configuring trunk links then VLAN info will not be carried to other switches.

Hi
Well, in LAN terms: - a trunk link is any link that carries more than one VLAN. Therefore it would be using dot1q or ISL.
An uplink is a more flexible term, can mean lots of things - but typically it's a link to a switch further towards the core - so from access to dist, dist to core, etc. It may or may not be a trunk link - often they are, but depending on your LAN design it may just carry one VLAN or it may be a layer 3 routed link.
