ITPEC IP April 2023 — Question 87 of 100
An embedded system is built into a larger device to perform dedicated functions of that device. In a rice cooker it controls heating and timing; in an air conditioner it reads sensors and regulates temperature, fans, and compressors. Embedded systems combine hardware and software and are usually optimized for their specific purpose.
Answer (c)
Why not others:
- (a) Expert system applies encoded specialist knowledge to inference or decision support
- (b) Enterprise system supports organization-wide business processes and information
- (d) Simplex system is not the term for a controller housed inside an appliance; simplex commonly describes one-way communication
Key rule: If a computer controller is integrated into a product to perform that product's specific function, it is an embedded system.
