解説
問 69
Incorrectア
A virtual computer is a mechanism (virtualization) that uses software to create multiple logical computer environments on a single physical machine; it is not dedicated hardware built to achieve ultra-high-speed scientific and technical computation.
- イ
正解 The correct answer is “イ” Supercomputer. The scenarios the question lists — “global-scale environmental simulation,” “genetic analysis,” and “processing massive amounts of calculations at ultra-high speed” — are all scientific and technical computations that require enormous numbers of floating-point operations, and a supercomputer is a computer specialized for such processing that pursues the highest possible level of computing performance. Supercomputers are actually used in fields such as weather and climate forecasting and drug discovery and life sciences, matching the description in the question exactly.
Incorrectウ
A general-purpose computer (mainframe) is a large machine whose main focus is stably processing large volumes of clerical work and transactions, such as a company’s core business operations, with high reliability; it was not developed for the purpose of ultra-high-speed numerical computation itself.
Incorrectエ
A microcomputer is a small, low-cost computer built around a single microprocessor (LSI) and is widely used for embedded control of home appliances and devices. It is not intended for ultra-high-speed, large-scale computation.
ここがポイント
- Grasp the definition that a supercomputer is a computer whose computing performance has been pushed to the extreme for scientific and technical computation (environmental simulation, genetic analysis, weather forecasting, and so on).
- Be able to distinguish among the types of computers classified by use (supercomputer / general-purpose machine = mainframe / microcomputer / virtual computer).
