• big data

• client/server model

use of a central computer (server) to manage resources on a network

• client/server model (for network)

• central processing unit (CPU)

• circuit

• Creative Commons

rather than using a local computer, this form of communication uses a network of remote servers to calculate and/or store data; has fostered new ways to communicate and collaborate

• symmetric encryption

the amount of logical reasoning (sometimes measured in lines of code) required to create an algorithm

• complexity (of an algorithm)

• convergence rate

• bandwidth

• Boolean logic

using computer algorithms to solve problems

• computing
