Why crystal is a preferred clock source?

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: 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: Main Boot Record is located in sector 0, track 0, head 0, cylinder 0 of the primary active partition

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: 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

Correct Answer: LIFO (Last In First Out) stack is used in 8085 In this type of Stack the last stord information can be retrieved first

Correct Answer: Accumulator register, Temporary register, Instruction register, Stack Pointer, Program Counter are the various registers in 8085

Correct Answer: IEEE 1394 (Firewire) supports the maximum of 63 connected devices with speeds up to 400 Mbps
