Question

i need help on computer engineering for beginners.

Answer 1

You want an introduction to software engineering or electrical? You'll need to be more specific really. Remember, the more readily people feel they can help someone, the more likely they are to actually help. You need to pose good questions to get good answers.

There's always Wikipedia. It's a good place to start if you unsure what you're looking for. Once you have more specific goals, you'll be able to engage others with complimentary interests.
