1. A certain RAM memory has a capacity of 8K X 16.
a) How many memory cells (locations) does this RAM have?
b) How many bits will be required to specify the address bus in this memory device?
c) How many I/O lines does it have?
d) What is its capacity in bytes?
2. What are the three basic computer buses?
3. What does DMA in the computer stand for? What purpose does it serve?
4. If we define the resolution of a Digital-to-Analog Conversion (DAC) device to be the reciprocal of its number of logic states in percentage, what will be the resolution of an 8-bits DAC device?
5. If a DAC device has a full-scale, or maximum, output of 15-V across 16 consecutive steps from ground of 0-V, then what is the maximum error in Volts for any given output voltage?
6. In a recent Synchronous DRAM (SDRAM), there is a term called "DDR." What does this term mean in relation to the clock signal?
7. What does ADC stand for?
8. According to the sampling theorem, the sampling frequency should be
a) less than half the highest signal frequency
b) greater than twice the highest signal frequency
c) less than half the lowest signal frequency
d) greater than the lowest signal frequency
9. In an existing local area network (computer network), the frequency of bus contention has been identified as higher than usual. Is this a good phenomenon?
10. Calculate the number of 128K memory blocks that will fit into a 1M address space. Write the start addresses for the blocks.
