Computers and Information
Processing
Computer - answerA programmable machine that converts raw data into useful
information.
Data - answerAll the files—documents, spreadsheets, pictures, songs, and so on—that
you create and store during the day-to-day use of your computer.
Information - answerData that is accurate, timely, and organized in a useful manner.
Ubiquitous computing (ubicomp) - answerSometimes called invisible computing,
technology that recedes into the background and becomes part of the user's
environment.
Smart home - answerA building that uses automation to control lighting, heating and
cooling, security, entertainment, and appliances.
Internet of Things (IoT) - answerThe connection of the physical world to the Internet.
Objects are tagged and can be located, monitored, and controlled using small
embedded electronics.
Embedded computer - answerA specialized computer found in ordinary devices, such
as gasoline pumps, supermarket checkouts, traffic lights, and home appliances.
Convergence - answerThe integration of technology on multifunction devices, such as
smartphones.
Mobile payment system - answerUsing a mobile device rather than cash or credit cards
to pay for items.
Information processing cycle (IPC) - answerThe process a computer uses to convert
data into information. The four steps of the IPC are input, processing, storage, and
output.
Input - answerThe process of entering raw data into a system.
Processing - answerThe manipulation, calculation, or organization of data to create
useful information.
, Output - answerThe display of processed data.
Storage - answerSaving digital information for archiving or later access.
Binary number system (base 2) - answerA number system that has only two digits—0
and 1.
Binary code - answerA system that represents digital data as a series of 0s and 1s that
can be understood by a computer.
Bit (binary digit) - answerThe smallest unit of digital data.
Byte - answerConsists of 8 bits and is used to represent a single character in modern
computer systems.
ASCII (American Standard Code for Information Interchange) - answerAn 8-bit binary
code set with 256 characters.
Unicode - answerAn extended ASCII set that has become the standard on the Internet
and includes codes for most of the world's written languages, mathematical systems,
and special characters. It has codes for over 100,000 characters.
Bit (b) - answer1/8
Byte (B) - answer1
Kilobyte (KB) - answer1,000 bytes
Megabyte (MB) - answer1 million bytes
Gigabyte (GB) - answer1 billion bytes
Terabyte (TB) - answer1 trillion bytes
Petabyte (PB) - answer1,000 TB
Exabyte (EB) - answer1,000 PB
Zettabyte (ZB) - answer1,000 EB
Yottabyte (YB) - answer1,000 ZB
Analytical Engine - answerA mechanical computer designed, but never built, in the early
nineteenth century by mathematician Charles Babbage that could be programmed using
punched cards.
