See the thing is that computer and science engg. deal with the science i.e. theory, the algorithm, the programming, creating new software,etc. Where as computer engg.deals with the hardware it's design etc. and electronics engg. is something different which deals with making smaller things much smaller by updating it's design and technology within it.

Thank you

Hello dear,

the basic difference between them is that computer science focuses on theory, algorithms and software engineering.

Electronic engineering, computer systems engineering and computer engineering will focus more on systems design and hardware.

computer is the study of how data and instructions are processed, stored, communicated by computing devices.

Hope This Helps.
