IoT in week 2&3

What is a Single Board Computer (SBC)?

• A computer built on multiple interconnected circuit boards.

• A complete computer built on a single circuit board with all components needed for functionality.

• A microcontroller used for simple embedded applications.

• A type of computer peripheral device.

What is a System on a Chip (SoC)?

• A computer system where all components are integrated onto a single chip.

• A collection of separate chips functioning together on a motherboard.

• An external chipset that enhances computer performance.

• A software system that manages computer hardware.

What is the main difference between an SBC and an MCU (Microcontroller Unit)?

• SBCs are used for simple tasks; MCUs handle complex computing.

• SBCs are complete computers with operating systems; MCUs are single-chip microcontrollers for specific control tasks.

• MCUs are larger and consume more power than SBCs.

• There is no difference; they are the same.

What is a diode?

• A device that allows current to flow in one direction only.

• A component that stores electrical energy in an electric field.

• A material that resists the flow of electric current.

• A device that opens and closes circuits electronically.

Which of the following are considered passive components?

• Transistors and diodes.

• Resistors, capacitors, and inductors.

• Microprocessors and microcontrollers.

• Integrated circuits and oscillators.

Active components include which of the following?

• Resistors and capacitors.

• Inductors and transformers.

• Diodes and transistors.

• Wires and connectors.

An example of a Single Board Computer (SBC) is:

• Raspberry Pi pico

• Raspberry Pi

• Intel Core i7 Processor

• NVIDIA Graphics Card

A System on a Chip (SoC) typically contains:

• Only the central processing unit (CPU).

• CPU, memory, input/output ports, and other features on a single chip.

• Just the graphics processing unit (GPU).

• External peripherals connected via buses.

Microcontroller Units (MCUs) are best suited for:

• Running complex operating systems like Windows or Linux.

• Simple control tasks in embedded systems.

• High-performance computing applications.

• Graphics rendering in gaming systems.

Which component can be charged and is crucial in power supply circuits?

•  Resistor

• Capacitor

• Diode

•  Inductor
