Where's MBR located on the disk?

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: Cache Memory is scratch pad of computer

Correct Answer: RAM: Read / Write memory, High Speed, Volatile Memory ROM: Read only memory, low speed, non volite memory

Correct Answer: ROM cannot be used as stack because it is not possible to write to ROM

Correct Answer: 1 Address lines to refer to the address of a block 2 Data lines for data transfer 3 IC chips 4 Processing data

Correct Answer: In 8086 Carry flag, Parity flag, Ausiliary carry flag, Zero flag, Overflow flag, Trace flag, Interrupt flag, Direction flag, and Sing flag

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

Correct Answer: The Micro Processor enters into Halt-State and the buses are tri-stated
