The I/O devices have a separate address space from memory

The I/O devices and the memory share the same address space

The memory and I/O devices have an associated address space

A part of the memory is specifically set aside for the I/O operation

Which component defines the system call interface to the operating system and facilitates binary portability?

Application Programming Interface

How does Boolean algebra contribute to the design of digital circuits?

It simplifies the implementation of desired functions

It helps in the analysis of economic data

It facilitates the design of analog circuits

It is primarily used for chemical engineering and physical engineering

Why is it essential to use symbolic representation of machine instructions?

It makes machine instructions more human-readable and understandable

It reduces the overall complexity of computer systems and user programs

It minimizes the need for memory storage for the user programs

It enables fastest execution of high level language instructions

What is a branch instruction?

The instructions that have as one of its operands the address of the next instruction to be executed

The instructions that are used to divide a program into multiple subprograms

The instructions that are used to pause the program

The instructions that are used to return to the beginning of the program

What is the role of the control unit in a processor?

The control unit in a processor directs and coordinates the execution of instructions, interpreting and managing the flow of operations within the CPU

The control unit's primary role is to perform arithmetic and logical operations within the processor, orchestrating the manipulation of data

The control unit only manages the flow of data between the CPU and external devices and does not play a significant role in executing instructions

The control unit is solely responsible for managing the flow of instructions from secondary storage to RAM and does not have a role in the internal operation of the CPU

How do data registers and address registers differ in some computer systems?

Address registers can be employed in calculating operand addresses, while data registers hold data.

Data registers are only used for stack-related operations

Data registers are used for indexed addressing, while address registers are used for data storage

Address registers are reserved for segmented addressing, while data registers are general-purpose

What is the main benefit of using ARM processors over other processors?

Low cost and low power consumption

Which statement is incorrect about RISC and CISC architecture?

CISC architecture requires more general-purpose registers than RISC architecture.

CISC architecture is more convenient for programmers than RISC architecture.

CISC architecture has more operands in an instruction compared to RISC architecture.

CISC architecture has a more flexible instruction set than RISC architecture.

What is the main benefit of using RISC over CISC?

RISC has faster instruction execution and simpler instruction decoding than CISC

RISC has more instructions and addressing modes than CISC

RISC has variable-length instruction formats and direct memory access than CISC

What is the benefit of using a superscalar organization over a scalar organization?

It increases the instruction throughput and improves the performance

It reduces the power consumption and the heat dissipation

It simplifies the instruction set and the compiler design

What does the term "instruction-level parallelism" refer to in computer architecture?

The degree to which instructions in a program can be executed in parallel

The number of processor cores in a multi-core CPU with multiple resources

The complexity of the instruction set architecture

The length of an instruction cycle with high level programing language

How does multithreading improve the performance of a processor?

It increases the instruction-level parallelism by issuing multiple instructions from different threads in the same cycle

It increases the thread-level parallelism by executing multiple threads on different cores or processors

It increases the utilization of the processor resources by hiding the latency of long-latency events such as cache misses or branch mispredictions

What is the significance of the program counter (PC) in the fetch phase of the instruction cycle?

The program counter (PC) in the fetch phase holds the memory address of the next instruction to be fetched and executed

The program counter (PC) is not used in the fetch phase, and its role is limited to tracking the number of instructions executed by the CPU

The program counter (PC) is responsible for executing instructions and has no specific role during the fetch phase

The program counter (PC) is only relevant in multi-core processors and does not contribute to the fetch phase of the instruction cycle in single-core systems
