Computer-Based Learning (CBL)
This is the practice of teaching with the computer as the primary tool to facilitate learning. It was hugely successful at tailoring the pace to individual students & was common place in the late 80s to early 90s. The main disadvantage of CBL was the limited level of interaction babies had with their teachers who in some cases basically left them in front of a computer to their own devices.

Computer-Supported Collaborative Learning (CSCL)
This is the practice of incorporating know-how as a way of facilitating learning amongst multiple individuals. Common examples of CSCL tools include blogs, media sharing mediums, wikis & whiteboards. Some advantages of Computer-Supported Collaborative Learning include its ability to increase student motivation, time saving as well as social interaction which helps create critical thinking.
