what is this slot in my computer?
I am using a toshiba laptop. Sorry, I dont have the model type. There is this weird slot on the left side of it. First off, there are three USB ports. 2 on the left side, and one on the right side. behinnd the 2 USB ports on the left side is the trapezoidal plug with all the metal prongs on it (name of this please)? but my real question is what is the slot in front of the 2 USB ports? the slot is about a centimeter tall, and 2" wide. on the side of the slot there is a button. if you push the button it pops out about a centimeter and a half. what is this slot for? sorry no pictures.
