2003 Honda Accord Sterter and alternator

Where excately is the alternator of my car?
Is a Honda Accord 2003 EX. I recently change the battery, because everyday in the morning was so hard and dificult start the car, but just on the mornings, until yesterday the car doesnt start at all. I can see the battery isnt or wasnt the problem, because all the panel are illuminated when I turn the key. So is this problem seems like the car need a new starter and alternator system? Thank you.
