Hello there! 

Greetings! 

Both branches are very similar the only main difference is that  ISE deals with only software while CSE deals with both software and hardware.

Computer Science Engineering (CSE) encompasses a variety of topics that relates to computation, like analysis of algorithms, programming languages, program design, software, and computer hardware. Computer Science engineering has roots in electrical engineering, mathematics, and linguistics.

Whereas,  Information Science and Engineering is a discipline which includes theories, standards, methods and innovations of various different domains like mathematics, cognitive science, information theory, etc to solve the complex IT problems. Information Science and Engineering focuses on collection, categorizations, strategizing, and storage of information as well how to analyze and interpret the raw data.  It is an area of professional practice to address the effective communication between information in the context of social, organizational, and individual needs in order to build the software or embedded applications for societal benefit.
