W.salam...
Dude I myself am a CS student but I will try to explain you the difference.. although you should search about it too. Electrical Engg is a vast field. Power engg, communication system engg and even electronics engg are its sub-fields. Computer Electrical Engineering basically deals with the electrical components of the computer i.e RAMs, Processors, registers, caches, flash drives, hard drives etc. So in computer electrical engineering, we study how the circuitry of these electrical components is designed. Fro example, a program that adds two variable a+b. At processor's hardware level this operation is performed by a AND gate (digital logic design). So its the job of computer electrical engg to design efficient hardware components through optimized circuit design.
Don't know much about Telecom EE but it must be dealing with subjects like communication systems, digital signal processing etc at their hardware level.
