Computer Architecture Quiz

Choose the most four basic functions of a computer.

• Moving data, storing data, processing data, controlling.

• Supporting operating system, accessing hard disks, supporting network connections, supporting HDMI ports.

• Reading disks, accessing network resources.

• Reading data from keyboard, printing data to monitor, allowing network connections.

Refers to the operational units and their interconnections that realize the architectural specifications.

• Computer architecture

• Computer function

• Computer organization

• Instruction set architecture

What is the most important function of the control unit (CU)?

• It manages the order of running instructions.

• It will read and process data from main memory.

• It directs the operation of the other CPU components.

• It will read instructions from main memory then decoding them.

The first generation of computers used _______ for digital logic elements and memory.

• Transistor

• Integrated Circuits

• Large-scale integration

• Vacuum Tubes

What is Memory Address Register (MAR)?

• Contains a word to be stored in memory or sent to the I/O unit, or is used to receive a word from memory or from the I/O unit.

• Employed to hold temporarily the righthand instruction from a word in memory.

• Contains the address in memory of the word to be written from or read into the MBR.

• Contains the address of the next instruction pair to be fetched from memory.

What is false about the von Neumann architecture?

• Data and instructions are stored in a single read-write memory.

• The contents of this memory are addressable by location, without regard to the type of data contained there.

• Execution occurs in a sequential fashion (unless explicitly modified) from one instruction to the next.

• Data is stored in main memory and instructions are stored in cache memory.

What is the maximum addressable memory of a 32-bit microprocessor with 24-bit address?

• 16 GB

• 16 MB

• 16 Gbits

• 16 Mbits

_______ interprets the instructions in memory and causes them to be executed.

• Registers

• CPU interconnection

• Arithmetic and Logic Unit (ALU)

• I/O Modules

• Control Unit (CU)

What is the most important characteristic of the Synchronous Bus?

• 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.

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

• No common clock signal controlling operation.

What is the correct order of memory access speed from fastest to slowest?

• Registers > Cache > RAM > SSD

• Cache > Registers > RAM > SSD

• Registers > Cache > SSD > RAM

• Cache > Registers > SSD > RAM

• All of the mentioned are wrong
