What does INTEGRATED video card mean?

my new computer comes with Integrated NVIDIA® GeForce® 6150 SE graphics . Im confused as to the integrated part. Does that mean it can not be changed to a better graphics card?|||GeForce 6150 SE graphics is an inexpensive chip built into the motherboard. You can change the Primary Display Device configuration in the BIOS if you want to install a graphics card in an available slot on the motherboard. The BIOS has an option where you can choose which kind of graphics to use.|||If it is a desktop system, it may have the option to bypass the on-board (part of the motherboard) video card if you wish to upgrade it with a plug in card. This is not an option with most laptops.|||i believe we have the same or similar pc. hp a6655f i have. you must have an hp too. but integrated means its in the motherboard. YES you can use a different graphics card without even having to mess with that. youll have a pci-e slot that you can put a new graphics card in, just plug in the dvi or hdmi cable in the new graphics card and make sure you get a psu that can support the new graphics card.|||Yes, it means it is solider right into the mother board and cannot be changed.
