Electronic engineering is a discipline dealing with the behavior and effects of electrons (as in electron tubes and transistors) and with electronic devices, systems, or equipment.
In the field of electronic engineering, engineers design and test circuits that use the electromagnetic properties of electrical components such as resistors, capacitors, inductors, diodes and transistors to achieve a particular functionality.
In Computer they design new hardware, the design of PDAs or the use of computers to control an industrial plant and Microprocessors etc.
Fundamental to electronic engineering discipline are the sciences of physics and mathematics as these help to obtain both a qualitative and quantitative description of how such systems will work.
Computer science (or computing science) is the study and the science of the theoretical foundations of information and computation and their implementation and application in computer systems
In Computer science engineering you read Mathematical logic, Number theory, Graph theory, Type theory, Category theory, Computational geometry, Concurrent, parallel, and distributed systems, Algorithm design, Software development, Computer architecture, Databases, Artificial intelligence, Computer graphics, Scientific computing etc.
