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 a 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

RISC has more registers and pipelines than CISC

What is the benefit of using a super-scalar 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 programming language

How does multithreading improve the performance of a processor?

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

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

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 (P) 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

Central processing unit (CPU) of IAS computer consists of

ALU (Arithmetic and Logic Unit) and CU (Control Unit)

Main memory and ALU (arithmetic and logic unit)

CU (Control Unit) and IO Module

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

Application Programming Interface

Which of the following statements is part of the Von Newmann principle?

The computer uses a program counter to indicate the location of the next statement

Computer can control all operations with a single program

Computer memory is not addressable

Each instruction must have a memory area containing the address of the next instruction

What is the distinction between Computer Architecture and Computer Organization?

Computer Architecture is the way the system is structured, while Computer Organization is those attributes of a system that are visible to the user

Organization the Way The system is structure a system that are visible to the user, while Computer Computer Architecture is the way the system is structured

Computer Architecture and Computer Organization are the same

Computer Architecture is slower than Computer Organization

Which of the following are the four basic functions that a computer performs?

Data processing, Data storage, Data movement, Control

Data processing, Data storage, Data movement, Interrupt

Data processing, Data storage, Interrupt, Control

Data processing, Interrupt, Data movement, Control

During the development process of the computer, which of the following statements is false?

The third generation uses transistor

The second generation uses transistors

The first generation uses vacuum tubes

The fourth generation uses integrated circuit

What electronic component is used to govern operations such as fetching, decoding, and performing arithmetic operations executed by a processor?

Using a analog to digital converter

What is true about IAS Memory Formats?

Both data and instructions are stored in the memory

The memory of the lAS consists of 1000 storage locations (called words) of 32 bits each

Only data is stored in the memory

Only instructions are stored in the memory

What is the most important characteristic of the Synchronous Bus?

The occurrence of events on the bus is determined by a clock

Data is transmitted at the same time

The occurrence of one event on a bus follows and depends on the occurrence of a previous event.

No common clock signal controlling operation

What is the primary purpose of cache memory in a computer system?

To store frequently used data for quick access

To store user files and documents

Why is cache design used in high-performance computing (HPC)? (Choose three correct answers)

Because there is a significant speed gap between the processor and the internal memory in HPC.

Because applications in HPC often require a large bandwidth to support intensive data processing

Because multiple processors are often working in parallel, caches provide a way to efficiently manage data required by these processors

Because power consumption can be a significant operational cost in HPC environments.

What is correct about increasing performance and endurance?

Hard Disk - NAND Flash - DRAM - SRAM

Hard Disk-DRAM - NAND Flash - SRAM

NAND Flash - Hard Disk - SRAM - DRAM

Hard Disk - DRAM - NAND Flash - SRAM
