ITPEC FE Morning October 2023 Question 15

A task is distributed over networked computers to gain processing capacity — that is grid computing.

Grid computing links many computers, often geographically spread and owned by different organisations, over a network and splits one large job among them, so together they act like a single high-performance computer. Volunteer projects that analyse scientific data on home PCs are a well-known example.

Answer (a)

Why not others:

• •(b) — describes virtualisation or emulation, which imitates hardware in software for portability and flexibility
• •(c) — describes a real-time system, whose requirements are deadlines on response and the time for which sensor data stays valid
• •(d) — describes IoT, where networked sensors are monitored and controlled from smartphones

Key rule: Grid computing adds up the capacity of many separate computers to solve one problem; virtualisation goes the other way, splitting or imitating one machine.
