Computer Chapter 1 : Topic 1.4
Von Neumann Computer Architecture
1 / 12
According to Von Neumann Architecture, which principle allows both program instructions and data to be stored together in the same memory?
Reasoning: The stored program concept is the key idea of Von Neumann Architecture, where instructions and data share the same memory.
2 / 12
A computer is executing a program by fetching instructions one after another from memory before processing them. Which feature of Von Neumann Architecture is demonstrated?
Reasoning: Von Neumann systems typically execute instructions sequentially through the fetch-decode-execute cycle.
3 / 12
In Von Neumann Architecture, why is a single memory used for storing both data and instructions instead of separate memories?
Reasoning: Using one memory for both data and instructions simplifies hardware design.
4 / 12
Which component of Von Neumann Architecture is primarily responsible for performing arithmetic calculations and logical operations?
Reasoning: The ALU performs mathematical calculations and logical comparisons.
5 / 12
A computer receives data from a keyboard, processes it, and displays the result on a monitor. Which units of Von Neumann Architecture are directly involved?
Reasoning: Input devices provide data, CPU processes it, and output devices present results.
6 / 12
Which component of the CPU controls and coordinates all activities taking place inside a Von Neumann computer system?
Reasoning: The Control Unit manages the execution of instructions and coordinates components.
7 / 12
A programmer saves a new software application into memory before execution. According to Von Neumann Architecture, where will the instructions be stored?
Reasoning: Von Neumann Architecture stores both data and instructions in the same memory.
8 / 12
During the fetch-decode-execute cycle, what is the correct first step performed by the processor before an instruction can be executed?
Reasoning: The processor must first fetch the instruction from memory.
9 / 12
Which statement best explains the role of memory in Von Neumann Architecture during program execution?
Reasoning: Memory provides the instructions and data needed by the CPU.
10 / 12
A computer slows down because instructions and data must share the same communication pathway between memory and CPU. This limitation is known as:
Reasoning: The Von Neumann Bottleneck occurs because instructions and data share the same bus.
11 / 12
Which sequence correctly represents the operation of a processor in Von Neumann Architecture while executing a program?
Reasoning: Instructions are first fetched, then decoded, and finally executed.
12 / 12
A student is identifying the major components of Von Neumann Architecture in a computer system diagram. Which set correctly represents those components?
Reasoning: The main components of Von Neumann Architecture are the CPU, Memory Unit, Input Unit, and Output Unit.
