Digital Information
A way of representing numbers using 1s and 0s
What is Binary?
a machine that can run a program
What is a Computing Device?
a general description of a task that can (or cannot) be solved with an algorithm
What is a Problem?
the collection of facts and patterns extracted from data
What is Information?

What is Keylogging?
8 bits
What is a Byte?
An agreed-upon set of rules that specify the behavior of some system
What is a Protocol?
putting steps in an order
What is Sequencing?
a relationship between two pieces of data, typically referring to the amount that one varies in relation to the other.
What is Correlation?
software intended to damage a computing system or to take partial control over its operation
What is Malware?

What is Digital Data?

What is a Packet?
a search algorithm that starts at the middle of a sorted set of numbers and removes half of the data; this process repeats until the desired value is found or all elements have been eliminated.
What is Binary Search?
a process that makes the data uniform without changing its meaning
What is Cleaning Data?
a process of encoding messages to keep them secret, so only "authorized" parties can read it
What is Encryption?
A process for reducing the number of bits needed to represent something without losing any information. This process is reversible.
What is Lossless Compression?
the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second
What is Bandwidth?
provides a "good enough" solution to a problem when an actual solution is impractical or impossible
What is Heuristic?
choosing a smaller subset of a data set to use for analysis, for example by eliminating / keeping only certain rows in a table
What is Data Filtering?
