Input, output and storage：練習問題

A web server requires high-speed access to frequently requested files and must handle a high number of concurrent read/write operations without mechanical failure. Which storage technology is most appropriate for this specific purpose?

A specialist research facility needs to capture 3D spatial data of ancient artifacts with high precision (\( < 0.1 \text{ mm} \)) for digital archiving. Which combination of input and storage technology would be most technically appropriate?

Which of the following statements best describes the primary role of ROM (Read Only Memory) in a contemporary desktop computer system?

In the context of embedded systems, such as a modern digital engine management system in a vehicle, why is Flash memory technically preferred over Magnetic storage?

A corporation implements a Virtual Storage solution to manage data across multiple physical devices. Which of the following best describes the technical abstraction provided by this specific implementation?

Explain why a Solid State Drive (SSD) is generally preferred over a Magnetic Hard Disk Drive (HDD) for the primary boot drive of a laptop, focusing on two physical characteristics.

In an embedded system like a smart thermostat, justify the requirement for both Read Only Memory (ROM) and Random Access Memory (RAM) for the device to function correctly.

Describe how virtual storage can be used to manage multiple physical storage devices as a single unit and identify one significant technical challenge regarding data retrieval speeds in this configuration.

A smart thermostat is designed to control a home's heating system and log temperature data over time.

(a) Explain the primary differences between RAM and ROM in the context of this thermostat's operation. [2]

(b) The thermostat needs to store historical temperature data locally for a period of five years. Identify a suitable type of secondary storage for this purpose and justify your choice. [2]

A medium-sized enterprise is upgrading its data center to handle large-scale database operations and remote employee access.

(a) Define the term virtual storage and describe two advantages it provides to a network administrator managing multiple physical storage arrays. [3]

(b) The enterprise must decide between using magnetic hard disk drives (HDD) or flash-based solid-state drives (SSD) for their primary database server. Analyze these two technologies in terms of their latency and durability under high-frequency write conditions. [3]
