August 2, 2021 By WatElectronics

This article lists 100 Embedded Systems MCQs for engineering students. All the Embedded Systems Questions & Answers given below includes solution and link wherever possible to the relevant topic.

An Embedded System (ES) is a platform in which multiple hardware and software type components are integrated together on IC technology for the purpose of application-specific or multi-application communication purpose. The entire design of an embedded system mainly depends on the programming part of IC.

Apollo Guidance Computer, was the first embedded system designed by developer Dr. Charles Stark Draper in the year 1980. He designed this embedded system to automatically gain output calculation from the system automatically which was based on mission-critical calculations for the system.

The systems complexity depends on the design and application task that the system is designed for in other terms the number of components required to design an embedded system depends on the application development. Sensors, ADC, DAC, actuators, FPGA, software, memory, external peripherals are a few of the components of embedded system architecture.

Embedded System provides advantage such as reliability, flexibility, and works in real-time. ES is used in various fields of areas such as AI, home automation, industries, etc. They lack in terms of upgradations of features, difficulty to backup data from the system, high maintenance cost, etc.
