Correct Answer: The data bus is Bi-directional because the same bus is used for transfer of data between Micro Processor and momory of input / output devices in both the direction
Correct Answer: Static RAM: no refreshing, 6 to 8 MOS transistors are required to form one memory cell, information stored as voltage level in flip flop Dynamic RAM: refreshed periodically, 3 to 4 transistors are required to form one memory cell, information is stored as a charge in the gate to substrate capacitance
Correct Answer: Because of high stability, large Q (Quality Factor) & the frequency that doesn't drift with aging Crystal is used as a clock source most of the times
Correct Answer: Three Logic Levels are used and they are High, Low, HIgh impedance state The high and low are normal logic levels & high impedance state is electrical open circuit conditions Tri-state logic has a third line called enable line
