Greetings!!

See the basic difference between BTech computer science and information science is this that Computer science includes details about computing, microprocessor, the designing of circuit and software development for super computer. While in Information technology it deals with storing data , retrieving data , designing information database and making computer network.

So if you take up computer science you will study about designing and management of information systems for software and hardware. You will be studying about algorithm, artificial intelligence, numerical computation, programming language.

While if you take up information science you get a chance to get to work in the field of implementation of computer system, networking, software engineering.

So you may choose your career field on the basis of the above mentioned information by seeing that in which of the field are you interested.

As far as scope is considered both the courses have their own importance and requirements, B tech in computer science is being more preferred these days however it totally depends upon your understanding and interest.

Hope this helps....
