問 61
- ア
正解 A blade server is a server form in which thin computers, each with its CPU, memory, and so on mounted on a single board (a blade), are inserted together in a dedicated chassis (enclosure) for use. Because power supply, cooling fans, wiring, and the like can be shared on the chassis side, many servers can be consolidated in a space-saving, high-density way, and it is used in places such as data centers. Choice ア, “Multiple board-type computers equipped with a CPU and memory are housed together in a dedicated chassis for use”, exactly matches this definition, so the correct answer is ア.
Incorrectイ
Making office software, email software, and the like available for use as web services on the Internet is a description of SaaS (Software as a Service) or ASP, and has nothing to do with a blade server, which refers to the physical structure of server hardware.
Incorrectウ
A computer embedded in devices such as home appliances and automobiles to perform specific control is a description of an “embedded system (embedded computer)”, which differs from a blade server, a general-purpose server.
Incorrectエ
Handwriting input on a liquid crystal display with a touch panel is a description of a tablet device (tablet PC) and the like, not a description of a blade server, which does not presuppose a display or input functions.
- Blade server = a form in which thin boards (blades) carrying a CPU and memory are housed multiple at a time in a dedicated chassis, sharing power supply, cooling, and so on to consolidate servers in a space-saving, high-density way.
- The key point is being able to distinguish its definition from similar, easily confused concepts (SaaS = providing web services, embedded system = built into devices, tablet device = touch-panel handwriting).
