Your Laptop should have a female VGA port on it. Different Apple brand laptops use various video adapters. If you do not have that adapter you check one out from technology services (see below).

The male audio cable goes where you insert your headphones.

Locate the cables on the desk and choose  
how you want to connect your laptop. VGA or HDMI?  
This decision will be based on what connection your 
laptop has.  
 
If your laptop has an HDMI port or can be adapted to then use the HDMI cable only.             
Newer PC and Mac laptops may have an HDMI, mini-display port or display port. The later two can be adapted to HDMI.
Older laptops will have VGA or require VGA adapters. 
Mac laptops manufactured after April 2010 support digital audio output via the mini-display port which when paired
with the correct adapter means only the HDMI cable is needed. 
Older Mac laptops will need to use the Mini Audio Plug for the sound.

Mini-display port adapters can be acquired from Technology Services  
or Equipment Checkout in BMC 5.104 and CMA 3.102.
