Yes there is quite a lot of differences but I would like to sum them up.
*CSE*
As per the curriculum, CSE includes 75–80% programming and the rest is covered in the studies of Networking, Operating Sysytem, Kernel, Cryptography, App Development, Web-App Development etc.
Whereas,
*IT*
Again, as per the curriculum, IT deals with 50–55% of Networking which will include studies of hardware like Switches, Hubs, most likely Cisco hardware as well as software knowledge which basically includes the network terms like data packet, TCP/IP, UDP, the Open System Interconnection model etc. And rest of the syllabus includes programming that would be used by the students to make their final year projects like writing a Web Crawler/Spider etc.
