Q. Explain about Unified Memory Architecture?
UMA signifies Unified Memory Architecture. It is an architecture that reduces the cost of PC construction. In this a part of main memory is essentially used as frame buffer. Therefore it removes the use of a bus for video processing. So it is less costly. However it isn't supposed to perform as well as AGP etc. in somecases it may give a better performance than bus-based systems. It's the interface used these days in low-cost motherboards.
