Inputs/Outputs
What is an input and what is an output?
Data you give to the computer - Input
Data you get from the computer - Output
What are the four types of memory we talked about?
RAM, ROM, cloud storage, external memory
How does data physically travel inside a computer?
Wires
What is binary?
A computer language made up of 0s and 1s
Give two examples of inputs
Mouse clicks
Typing
Sound
Pictures
Movement etc
What is the different between RAM and ROM?
RAM is short term (volatile) and cannot store data when the computer is turned off.
ROM is long term (non-volatile) and stores data even when the computer is turned off.
Where does all the data in a computer get processed?
CPU - Central Processing Unit
What is the physical form of the information that travels inside a computer?
Electricity
When doing a google search, I typed in what I wanted to search up and pressed enter. What two inputs did I give the computer? What output did it give me?
Inputs- typing in search terms and pressing enter
Outputs - seeing the search results on my screen
How does cloud storage work?
Data is stored on another computer (a server) and we access it through the internet using log in information.
What gets stored in each of the following: RAM, ROM, hard drive
RAM - data an application needs while it’s running
ROM - data the computer always needs such as how to start up
Hard-drive: All our files
How is binary related to how information physically travels inside a computer?
Binary is a representation of wires with and without electricity.
0s - wires with no electricity
1s - wires with electricity
Different patterns of these tell the computer what to do in different situations
What are examples of data that can be inputs or outputs? In what context would they be an input or an output
Sound: input when talking to siri, creating a voice note, etc
Output when siri talks to you, listening to music, etc.
Where is RAM located inside the computer?
Motherboard :)
What part (other than CPU and RAM) on the motherboard are needed to display things on your screen?
Video card/graphics card
Explain how a computer would open a picture on your screen. Start from the button click to open it all the way to the picture showing up on your screen.
what is the input? How does the data travel? Where all does it go inside the computer? How does it get back to the screen? What is the output?
Input: mouse click
It travels as a patten of wires with and without electricity (can be represented to us as 1s and 0s aka binary) to the CPU.
It needs the CPU RAM and video card
It travels back the same way it came in a pattern of wires with and without electricity.
The output is the picture displayed on the screen.
