Hardware Questions

A SIPO and AND gate circuit can detect this sequence.The output of SIPO is connected to a four input AND gate ,the third SIPO output should be connected through a NOT gate.When the 1101 sequence is loaded in to the SIPO the AND output goes HIGH otherwise keeps LOW.

The Micro Processor enters into Halt-State and the buses are tri-stated. 

8085 is a one address microprocessor. In 8085 interrupts  are classified by software and hardware interrupts.

RST 6.5 & RST 5.5 are level-triggering interrupts.

1. Address lines to refer to the address of a block

2. Data lines for data transfer

3. IC chips

4. Processing data

Intel's 80386 was the first 32-bit processor, and since the company had to backward support the 8086. All the modern Intel-based processors run in the Enhanced mode, capable of switching between Real mode (just like the real 8086) and Protected mode, which is the current mode of operation.

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

Microprocessor is a program-controlled device, which fetches the instructions from memory. decodes and executes the instructions. Most Micro Processors are single-chip devices.
