hiya anyone interested in helping me out with a question? an expansion memory adapter may be required when A, an application requires access to more than is presant within the system board, B a hard disk unit is to be installed within the system unit. C all of the system motherboard expansion slots have adaptors or option cards fitted D an EGA graphics adaptor card is fitted in place of an MDA or CGA unit. i think it is c but can any one confirm or argue and why thanks

A) an application requires more memory... If their are no free expansion slots on the mother board how would you fit an expansion memory adapter in? This would rule out C.

thanks borrelli133

G'day, I'll second that; it's A for me to. If you require more memory than is on the system board (assuming you have filled all the chips...) then you must decode extra using an expansion slot (quite common in the old PCs). I think the others are less likely...if you select C as your answer-exactly where are you going to put this memeory expansion card??? The video option is possible but video RAM usually comes with the card if there is more than what is allocated for it by the BIOS ie under 1 Meg. regards, Elric
