Explores the functionality of a computer in relation to the hardware and their interfaces
Compare the features of Blu-Ray discs and flash memory cards in terms of portability and capacity.
How does grid computing differ from parallel computing in its application?
What is one advantage of the stored program concept in Von-Neumann architecture?
What are the primary functions of the Arithmetic and Logic Unit (ALU) in Von-Neumann architecture?
How does the Control Unit (CU) contribute to the fetch-execute cycle?
Answers and Descriptions:
Answer: Blu-Ray discs offer high capacity (up to 50GB) but lower portability, while flash memory cards are highly portable with moderate capacity (up to 1TB).
Description: Blu-Ray discs suit high-capacity media storage, like movies, but are less portable, while flash memory cards are ideal for portable devices due to their compact size, used in cameras and smartphones.Answer: Grid computing uses distributed systems for large-scale tasks, while parallel computing uses multiple processors within a single system.
Description: Grid computing connects geographically dispersed computers for tasks like scientific research, unlike parallel computing’s localized task division within a single machine, enhancing scalability for complex projects.Answer: It allows programs to be modified easily by changing memory contents.
Description: Storing instructions in memory enables dynamic program updates without hardware changes, a cornerstone of modern computing flexibility, allowing software upgrades and adaptability.Answer: The ALU performs arithmetic operations (e.g., addition) and logical operations (e.g., comparisons).
Description: The ALU is critical for executing calculations and decision-making tasks, forming the computational core of the CPU, essential for processing data in all computing tasks.Answer: The CU fetches instructions, decodes them, and coordinates execution with other components.
Description: The CU orchestrates the fetch-execute cycle by directing data flow and ensuring instructions are processed in sequence, critical for the systematic execution of programs.
