Unit 2 Binary/Data Terms

Bits: Smallest unit of computer information. The bit can either be on(1) or off(0).
Bytes: Unit of computer information. Usually will feature 8 bits
Hexadecimal / Nibbles: Half of a byte, so this uses only 4 bits
Binary Numbers: Represent with 0s and 1s
Unsigned Integer: Does not have a plus or minus indicator in front of the value
Signed Integer: Has a plus or minus sign in front of a value
Floating Point: Can be a positive or negative decimal
Binary Data Abstractions:
Boolean: Variable which has a value of either True or False
ASCII: American Standard Code for Information Interchange, encodes data for communication, allows a multitude of symbols to be represented
Unicode: System used to store and process text data
RGB: red, green, blue color model, can use data values to represent colors
Data Compression:
Lossy: (note discussed yet)
Lossless: (note discussed yet)

Unit 3 Algorithm/ Programming Terms

Variables: Stores a value in a data set, there are multiple data types
Data Types: types of data, include string(letters/words), integers(numbers), boolean(T/F), float(decimals)
Assignment Operators: operators which assign a variable a value, usually =
