Basic values or facts. - CORRECT ANSWER Data
Data that has been organized and/or processed in a way that is useful in solving
some kind of problem. - CORRECT ANSWER Information
Data that lacks context. - CORRECT ANSWER Unstructured Data
The representation of all data as strings of 1s and 0s. - CORRECT ANSWER Binary
Digits
Reducing the amount of space needed to store a piece of data. - CORRECT
ANSWER Data Compression
The size of the compressed data divided by the size of the original data, resulting
in a number between 0 and 1. - CORRECT ANSWER Compression Ratio
A data compression technique where the data can be retrieved without losing any
of the original information. - CORRECT ANSWER Lossless Compression
,A data compression technique in which some information is lost in the process of
compaction. - CORRECT ANSWER Lossy Compression
The balance between accuracy and size when dealing with data representation
and compression. - CORRECT ANSWER Tradeoff in Data Representation
Data that is continuous and infinite, representing the natural world. - CORRECT
ANSWER Analog Data
Data that is finite, as computer memory and hardware have limited capacity. -
CORRECT ANSWER Digital Data
Video played as it is downloaded from the Web, emphasizing the need for
efficient data representation. - CORRECT ANSWER Streaming Video
Computers that deal with a vast array of information categories including
numbers, text, audio, images, and video. - CORRECT ANSWER Multimedia Devices
The constraints that previously required data to be kept small due to the cost of
storage. - CORRECT ANSWER Storage Limitations
Inherent limitations that define the maximum number of bits or bytes that can be
transmitted in a fixed amount of time. - CORRECT ANSWER Bandwidth Restrictions
A representation where values grow infinitely large and small. - CORRECT ANSWER
Continuous Number Line
,The attempt to represent an infinite world on a finite machine. - CORRECT
ANSWER Finite Representation
The goal of representing enough of the world to meet our computational
requirements. - CORRECT ANSWER Satisfaction of Computational Needs
The concept that objects move through continuous and infinite space. - CORRECT
ANSWER Real World Movement
The infinite range of values between two integers. - CORRECT ANSWER Numeric
Space
The methods by which different types of data are stored and manipulated on a
computer. - CORRECT ANSWER Representation of Data
Categories of data including numbers, text, audio, images, and video. - CORRECT
ANSWER Types of Data
The process of organizing and representing data effectively. - CORRECT ANSWER
Data Management
A continuous representation, analogous to the actual information it represents. -
CORRECT ANSWER Analog Data
, A discrete representation, breaking the information up into separate elements. -
CORRECT ANSWER Digital Data
An analog device where the mercury rises in a continuous flow in the tube in
direct proportion to the temperature. - CORRECT ANSWER Mercury Thermometer
The process of marking the tube of a thermometer so that the current
temperature can be read. - CORRECT ANSWER Calibration
A number system that uses only two possible values, typically represented as 0
and 1. - CORRECT ANSWER Binary System
A behavior of digital signals that jump sharply between two extremes. - CORRECT
ANSWER Pulse-Code Modulation (PCM)
The loss of information as electronic signals move down a line due to
environmental effects. - CORRECT ANSWER Signal Degradation
The process of periodically restoring a digital signal to regain its original shape. -
CORRECT ANSWER Reclocking
The smallest unit of data in a computer, which can be either 0 or 1. - CORRECT
ANSWER Bit
Using more than one bit to represent more than two things. - CORRECT ANSWER
Multiple Bits
