SDRAM
A generic name for various kinds of dynamic random access memory: DRAM that are synchronized with the clock speed that the microprocessor is optimized for. This tends to increase the number of instructions that the processor can perform in a given time. The speed of SDRAM is rated in MHz rather than in nanoseconds (ns). This makes it easier to compare the bus speed and the RAM chip speed. You can convert the RAM clock speed to nanoseconds by dividing the chip speed into 1 billion ns (which is on...

You can control depth of field by varying three factors: 1) the size of the aperture 2) the distance of the camera from the subject 3) the focal length of the lens. If you decrease the size of the Aperture, the depth of field increases; if you focus on a distant subject, depth of field will be greater than if you focus on a near subject; and if you... |
