12. USB Flash Drive:  A small, portable flash memory card that plugs into a computer's USB port and functions as a portable hard drive.  The first commercial USB drive offered 8MB of space, but current drives have reached 128GB of free storage and are getting cheaper every day. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

13. - Serial Port (COM):  Also known as a RS 232 port  New Computers do not come equipped with a COM port anymore. This port was used commonly for connecting a mouse, phones and other networking devices. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

14. - Parallel Port (LPT): Almost obsolete, this port was mainly used to connect old Printers. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

15. - USB Port:  A standard in all Computers today.  Allows connection of all kinds of devices, from Printers, input devices to external hard drives. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

16. - VGA Port:  A blue port used to connect the PC Monitor.  Currently being replaced with DVI and HDMI Professor: Nabil Elmjati IB100 Introduction to computer Sciences

17. - DVI Port: A white port that is replacing the VGA. DVI allows a computer to connect to a high definition monitor or TV. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

18. - HDMI Port: Like the DVI, an HDMI allows the computer to connect to newly released monitors and current High Definition Television. One major advantage of HDMI is the ability to transfer both HD Video and Audio using one cable only. Professor: Nabil Elmjati IB100 Introduction to computer Sciences
