26. As in DRAM, SRAM must be continually refreshed in order to maintain the data. 27. Dual channel memory is a function of the memory controller that requires DDR, DDR2 or DDR3 memory modules installed into the same color or paired slots. 28. Asynchronous components are in step with the CPU's clock cycle. Flashing BIOS is the process of upgrading or refreshing the programming stored on the ROM chip firmware. RAM access time is usually measured in nanoseconds, and hard disk access time is usually measured in milliseconds. 26.
