A
A single binary digit of either a 1 or 0
bit
Using the power of computers to solve problems
computer science
Information that can be expressed in a numerical form.
Digital Information
What does the numbers 1 and 0 represent in binary
1 represents on and 0 represents off
A base 2 number system, two digits of 0 and 1 which is the language our computers speak.
binary system
Malware, shutting down critical infrastructure, stealing sensitive data, loss of privacy
The downside of Computer Science
The process of simplifying complicated data into manageable chunks
data abstraction
A prediction made by Gordon Moore in 1965 that computing power will double every 1.5-2 years, it has remained more or less true ever since.
Moore's Law
What number system is made up of 16 digits and what are they
Hexadecimal Number System
0-9A-F
A combination of eight bits together
Byte
A set of rules governing the exchange or transmission of data between devices.
protocol
Protocol for encoding text
ASCII (American Standard Code for Information Interchange)
Short for "picture element", the smallest element of a digital image, typically a tiny square or dot that contains a single point of color of a larger image.
pixel
Numeric coding scheme that allows us to represent colors by using a combination of red, green, and blue light in each pixel - there are 24 bits per pixel
RGB
How is RGB represented in Binary
8 bits each for Red, Green, and Blue for a total of 24 bits
How RGB is represented in Hexadecimal
2 digits each with a pound sign in front
Used to brighten our digital images. We add the same set value to each of our RGB colors, making sure to not go over the value of 255
Brightness filter
Same as above but we are subtracting instead of adding a set value to each RGB color and using max in place of min to not go below a zero value.
darkening filter
