The Von Neumann architecture is based on the concept of:
Separate memory for data and instructions
Single memory for both data and instructions
Only sequential execution of instructions
Hardware-controlled parallelism
In a digital computer, the Control Unit (CU) is responsible for:
Performing arithmetic operations
Storing instructions permanently
Directing the flow of data and execution of instructions
Increasing clock speed
Which of the following is NOT a basic functional unit of a digital computer?
Input Unit
Output Unit
Arithmetic and Logic Unit (ALU)
Compiler Unit
An operand in computer instructions refers to:
The operation to be performed
The data on which operation is performed
The type of addressing mode
The memory hierarchy level
The Instruction Set Architecture (ISA) defines:
The physical size of the computer
The programming language syntax
The interface between hardware and software
The semiconductor material used
The instruction LOAD R1, 2000 means:
Store the contents of R1 into address 2000
Load the contents of memory location 2000 into R1
Move the address 2000 into R1
Clear the contents of R1
Which of the following is NOT an addressing mode?
Immediate addressing
Direct addressing
Indirect addressing
Conditional addressing
The program counter (PC) in instruction sequencing holds:
The address of the current instruction
The address of the next instruction to execute
The result of the last operation
The base address of memory
In instruction encoding, the opcode field specifies:
The type of operand
The operation to be performed
The address of data
The execution time
Interaction between assembly language and high-level language occurs because:
Assembly is easier to learn than high-level languages
High-level programs are translated into assembly/machine code for execution
Assembly can directly replace high-level programs
Both use the same instruction syntax
