Binary 1
A way of representing information using only two options.
Binary
A contraction of "Binary Digit"; the single unit of information in a computer, typically represented as a 0 or 1
Bit
Data with values that change continuously, or smoothly, over time. Some examples of analog data include music, colors of a painting, or position of a sprinter during a race.
Analog Data
A process for reducing the number of bits needed to represent something without losing any information. This process is reversible.
Lossless Compression
A work or invention that is the result of creativity, such as a piece of writing or a design, to which one has rights and for which one may apply for a patent, copyright, trademark, etc.
Intellectual Property
8 bits
Byte
Error from attempting to represent a number that is too large.
Overflow error
Data that changes discretely through a finite set of possible values
Digital Data
A process for reducing the number of bits needed to represent something in which some information is lost or thrown away. This process is not reversible.
Lossy Compression
A collection of public copyright licenses that enable the free distribution of an otherwise copyrighted work, used when an author wants to give people the right to share, use, and build upon a work that they have created
Creative Commons
Error from attempting to represent a number that is too precise. The value is rounded.
Round-off error
Convert the binary (base-2) number 1011 to decimal (base-10).
11
A process for creating a digital representation of analog data by measuring the analog data at regular intervals called samples.
Sampling
Jorge is sending a large image file to a friend as part of a shared classroom project. What will happen if Jorge opts to compress the image before sending it?
The image will require fewer bits in order to be represented.
What is the name for the plastic or metal tube on the ends of shoelaces?
Aglet
Your computer uses 5 bits to represent decimal numbers (0, 1, 2, 3 and so on) in binary. What is the SMALLEST number for which an overflow error occur?
32
Convert the decimal (base-10) number 75 to binary (base-2).
01001011
You take a photo of a painting with a smartphone which stores the photo as an image file. Which is the analog image and which is the digital image, explain?
analog - painting
photo - digital
What is the national animal of Scotland?
Unicorn
Arman takes a picture with his smartphone which he subsequently posts online. Beatrice finds the picture online and posts a copy of it on her website with an attached Creative Commons license. In this scenario, who owns the photo?
Arman owns the photo because he was the original creator and did not license the work.
How does a computer represent data?
A computer represents data as bits which is either a 0 or a 1
How many total numbers can be represented with an 6-bit binary (base-2) system?
64
What is a group of flamingos called?
flamboyance
Which is typically better at reducing the number of bits bits needed to represent a piece of data. Lossless or Lossy?
Explain.
Since lossless compression keeps all the information from the original item, it cannot do as good a job of reducing the number of bits as lossy compression where some of the original information is lost.
What year was the Internet opened to the public?
1993
