Hi, so basically electronics and communication engineering field involves researching, designing, developing, and testing of electronic equipment used in various systems.

They basically deals with microprocessors, solid-state devices, digital and analog communication, analog integrated circuits, microwave engineering etc.

Every physical device have microprocessors on them. Your tablet, phone, laptop, television etc.

This is a great field to pursue and have a good and settled job market.

And basically computer science engineering is a totally different field. A computer science engineer basically deals with softwares (builds them, works on them etc).

Computer science is a vast field with variety of technologies such as Artificial Intelligence, Cyber Security, Machine Learning, Internet Of Things, etc. A computer science engineer works on programming languages such as Python, C, C++, Java, JavaScript etc.

A computer science engineer have a great salary package too though it depends what skills he have.

Computer science as a carrier is a great option.

Hope this is helpful.
