Chapter 2:Embedded Systems Flashcards
What is an Embedded System?
An Embedded System is a single painted circuit board containing all the functions of a computer.
What are Embedded Systems?
Embedded Systems are a combination of computer hardware and software designed for a specific function or dedicated task.
Name examples of Embedded Systems.
Examples of Embedded Systems include:
- Industrial Robots
- GPS Receivers
- Digital Cameras
- DVD Players
- MP3 Players
- Microwave Ovens
- Photocopiers
- Gaming Consoles
- Set top boxes
- Wireless Routers
What are the advantages of Embedded Systems?
Advantages of Embedded Systems include:
- Do not need much secondary storage
- Do not need much primary storage
- Low clock speed
- Low spec components are cheaper and consume less power.
What characterizes Analog signals?
Analog signals are continuous and represent continuous data.
How is information translated in Analog technology?
In Analog technology, information is translated into electric pulses of varying amplitude.
What are examples of Analog Inputs?
Examples of Analog Inputs include:
- Temperature
- Light Intensity
- Sound Intensity
- Magnetometer
What is an example of an Analog Output?
An example of an Analog Output is a Speaker (Sound).
What characterizes Digital signals?
Digital signals are discrete and represent information in binary format (1 or 0).
How are states represented in electrical circuits for Digital technology?
In electrical circuits, states are represented by voltage (5V = on or 0V = off).
What are examples of Digital Inputs?
Examples of Digital Inputs include:
- Button (on/off)
- PIR sensor
What are examples of Digital Outputs?
Examples of Digital Outputs include:
- Buzzer
- LED
- LED display
What are examples of Micro Bit Inputs?
Examples of Micro Bit Inputs include:
- Sensor (Light, Temperature, Movement)
What are examples of Micro Bit Outputs?
Examples of Micro Bit Outputs include:
- Speaker
- LED
