Embedded Systems Practice Exam

About Embedded Systems
An embedded system is a microprocessor-based computer hardware system with software that is designed to perform a dedicated function, either as an independent system or as a part of a large system. At the core is an integrated circuit designed to carry out computation for real-time operations.

Embedded systems are managed by microcontrollers or digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA), GPU technology, and gate arrays. These processing systems are integrated with components dedicated to handling electric and/or mechanical interfacing.

Embedded systems programming instructions, referred to as firmware, are stored in read-only memory or flash memory chips, running with limited computer hardware resources. Embedded systems connect with the outside world through peripherals, linking input and output devices.

The basic structure of an embedded system includes the following components:
•    Sensor: The sensor measures and converts the physical quantity to an electrical signal, which can then be read by an embedded systems engineer or any electronic instrument. A sensor stores the measured quantity to the memory.
•    A-D Converter: An analog-to-digital converter converts the analog signal sent by the sensor into a digital signal.
•    Processor & ASICs: Processors assess the data to measure the output and store it to the memory.
•    D-A Converter: A digital-to-analog converter changes the digital data fed by the processor to analog data
•    Actuator: An actuator compares the output given by the D-A Converter to the actual output stored and stores the approved output.

Embedded Systems has gained immense popularity across the globe resulting in huge demand for certified professionals.

Why is Embedded Systems important?
The importance of embedded systems is:
•    They are small, fast and power tools used in many gadgets and equipment that have become a part of our everyday lives.
•    To have real-time application guarantee its performance (temporal as well as functional performance) you need embedded systems
•    To achieve a given task set or functionalities with constrained resources, we use embedded systems. (This is actually a quality of embedded systems)
•    Everyone, now-a-days, wants a small phone/computer which could do many things for them. Achieving this while keeping the product cost low requires embedded systems.

Certified Embedded Systems professionals, executives and managers are in high demand in companies across the globe.
