This episode continues our discussion on the Basics of Digitizing Data. In this episode, you will learn about the electronic circuitry of a computer. At the most basic element within your computer is the switch. It’s on or off, just like the light switch on your wall. On is 1 and off is 0.
Your key takeaways are:
- Computers handle digital signals
- Signals are electrical voltages
- Digital allows us to best represent the real world within a finite machine
- A digital “off” state is represented as 0
- A digital “on” state is represented as 1
- You can combine circuits to achieve a pattern of 1s and 0s
Computer circuitry is digital:
Digital vs. Analog
What is digital?
These are the main distinctions between Analog and Digital signals:
- Continuous flow of data
- Infinite flow of data
- Proportional to the real world
- Digital is discrete and finite
- Digital has 2 states
- Computers can only handle so much information
- Allows the computer to store and process data and instructions
- Breaks up information into separate elements
What is an off state and an on state in electronics?
An off state -> 0 (also a “false” state)
An on state -> 1 (also a “true” state)
Convert the following into 1s and 0s:
This is 8 bits, the basics of computer circuitry.
