Understanding Computer Architectures: Von Neumann and Harvard

What does computer architecture primarily define?

• The interaction between software and hardware

• The electrical consumption of a computer

• The color and design of the computer case

• The marketing strategies for computer sales

What is the primary role of a CPU in a computer system?

• To manage external communications

• To provide structural support to the hardware

• To enhance the audio output of the system

• To execute instructions and manage data flow

Which architecture uses a single memory unit for both instructions and data?

• Von Neumann Architecture

• Parallel Architecture

• Harvard Architecture

• Decentralized Architecture

Which component in microarchitecture is responsible for arithmetic operations?

• Memory Controller

• Control Unit

• Arithmetic Logic Unit

• Data Processor

What does DMA stand for and what is its function?

• Direct Memory Access, allows devices to access memory without CPU involvement

• Data Management Architecture, manages data storage

• Dynamic Memory Allocation, allocates memory dynamically

• Direct Module Access, provides direct access to hardware modules

What is a significant advantage of Harvard architecture over Von Neumann architecture?

• Lower manufacturing costs

• Simpler bus structure

• Reduced risk of data corruption

• Unified memory access

What is the main disadvantage of Von Neumann architecture related to its processing?

• It does not support parallel execution of instructions

• It requires manual data management

• It allows only parallel execution of instructions

• It supports only high-level languages

Which architecture was first proposed by Howard H. Aiken?
