As per Indian education system and job recruiters (hiring consultants), not much of a difference.
But to be honest, there is a very fine line of difference between CSE and IT stream.
Information Technology: Specific technologies related to collecting, manipulation and conveying information. This stream came into existenceduring internet era and became super famous (and also due to greediness of Engg colleges you know extra stream, so extra seats, extra money), kind of a younger sibling to CSE. Any technology highly dependent on information like Computer Networking, Web technologies, mobile technologies (apps), Computer Graphics, digital marketing and advertising, e-commerce and many more come under this stream. All the mentioned topics that got revolutionized by advent of internet. So, it would be wise to call this stream as Internet Technologies rather than Information Technologies.
