01․ The relation among IC (Instruction Cycle), FC (Fetch cycle) and EC (Execute Cycle) is
Instruction cycle consists of fetch cycle and execute cycle.
02․ Each instruction in an assembly language program has the following fields 1. Label field 2. Mnemonic field 3. Operand field 4. Comment field What are the correct sequence of these fields?
The correct sequence of any Instruction in an assembly language program is Label field, Mnemonic field, Operand field and Comment field.
03․ Total number of instructions in 8085 microprocessor assembly language is
8085 microprocessor assembly language consists of 246 instructions.
04․ An 8-bit microprocessor signifies that
An 8-bit microprocessor signifies that it has 8-bit data bus.
05․ Which one of the following microprocessor is not an 8-bit microprocessor
8085, Z-80 and 6502 are 8-bit microprocessors whereas 68000 is a 16-bit microprocessor.
06․ Which one of the following microprocessor has 16-bit data bus?
68000 is a 16-bit microprocessor. So it has 16 data lines.
07․ A microcomputer consists of
A microcomputer consists of a microprocessor, memory and I/O devices.
08․ The address bus of any microprocessor is always
Address bus of any microprocessor is always Unidirectional. Address bus points only memory location so it is unidirectional.
09․ The data bus of any microprocessor is always
A data can be moved from microprocessor to memory and also from memory to microprocessor. So Data bus of any microprocessor is always Bi-directional.
10․ The multiplexing of address bus and data buses is used in
Multiplexing of address bus and data buses depends upon internal architecture of any microprocessor.
