What do you mean by AD bus in microprocessor?
ad is multiplex address data line bus
What do you mean single and double handshaking of microprocessor 8086?
They are the ways of transmitting parallel data to the microprocessor. In single handshake, a peripheral device first sends a "Strobe signal" to the microprocessor to indicate that it is ready to send data. The microprocessor , upon detecting the strobe signal, opens up its input port and receives the data. After receiving data, it sends an "Acknowledge signal" to the peripheral to indicate that transmission has been completed.A transmission session has been completed. In double handshake, first the peripheral device sends a strobe signal, the microprocessor, sends the acknowledge signal to indicate that it is ready to receive data. After which data is received.After sending data, the peripheral sends a strobe signal to indicate data transmission completion, due to which, the microprocessor drops its acknowledge signal and a session has been completed. The only difference in the two is that, in double handshake, the peripheral is informed about the microprocessor's readiness to receive data. This is doesn't happen in single handshake. So the name follows "double handshake", literally meaning "double confirmation".
Which is better in 8086 and 8051?
If you mean greater (more) 8086.
What do you mean by multiplexing the bus?
If you have less no of data than the no of bits of data or address to b transfer Multiplexing mean to manage given busses in such a way that data or address can be transferred perfectly
The is another name for the computers microprocessor or sometimes for the box that contains the computers microprocessor and memory and to which the monitor keyboard and mouse are attached?
I'm not sure What you mean exactly ? Another name for the Microprocessor? That is known as (CPU) Which is the heart of a Computer. Which Controls Logic, and Control Operations, Reads, Writes, Executes Bits Bytes Data, and is the Primary Control for Processing Data (Centeral Processing Unit) MicroProcessor,''Single circuit Chip''
What does physical address mean?
The physical address is the final address that is presented to the bus, at the pins of the microprocessor chip, to form the address of the desired item in memory.In the 8085, physical and effective addresses are one and the same.In the 8086/8088, the physical address is the effective address plus 16 times one of the segment registers.In higher level processors, such as the 80386 and beyond, the physical address is formed by lookup of the effective address in a page table to convert from virtual/effective address to physical, or linear, address.The effective/virtual address is the address generated by the instruction and the programmer, without regard to any underlying addressing scheme. This is the address used when considering the "programming model", in "user mode".
What do you mean by IVT in 8086?
Interrupt vector table
What do you mean by- 8085 microprocessor?
The 8085 was the next generation of the 8080, providing operation on a single +5V power supply, a multiplexed address/data bus, integration of the system controller and clock generator, new automatically vectored interrupts, a few 16 bit instructions, and serial I/O.
What do you mean by 8 bit?
An 8 bit microprocessor is a 'microprocessor' which only has an 8 bit wide databus.
What is parity interrupt?
There is no parity interrupt on the 8085 or 8086/8088. If you mean a memory parity interrupt, that is a function of system design, not a function of the particular microprocessor involved. Generally, a memory parity error is fatal, so one would typically place it on a non-maskable interrupt, such as TRAP on the 8085, or INT 2 (NMI) on the 8086/8088. This assumes, of course, that the memory parity error does not just crash the processor.
What is the segment of the data bus that connects RAM to the processor?
The usage of "segment" and "data bus" in the question appears inconsistent, and does not completely make sense. If you mean the data segment in the 8086/8088, then this is the region of memory mapped by the Data Segment (DS) register, usually reserved for operands in memory. If you are talking about the 8085, then the question does not make sense at all.
What is the use of insertion queue in 8086?
Maybe you mean the prefetch queue?
