Bandwidth, both within the college and in connecting to the Internet, is a shared, finite resource. To manage web resources so that they are available to the most users, users can download no more than 4 files from the Engineering College web server at the same time. The policy pertains to specific file types: audio and video files -- mp3, mpeg, wav, avi, etc. -- and pdf, ppt, and iso files. You will get a browser error message when attempting to download more than 4 files of those types.
