Using computer technology to track, record, and evaluate worker performance, often without the knowledge of the worker.
computer-aided design (CAD)
The use of computers to draw products or process designs on the screen.
computer-aided instruction
Software programs for teaching that combine drill & practice software and tutorial software.
drill & practice - repetitious practice
computer-aided manufacturing
when a product's design is fed into the machine and the machine creates the product

can also be used to create a template for circuit designs to be etched onto chips.
also called computer-instructed manufacturing
computer-integrated manufacturing (CIM)
the combination of computer-aided design (CAD) and computer-aided manufacturing (CAM)

the design is created on the computer and the computer manufactures the design
copy protected
Produced in a way that prevents any PHYSICAL copying
examples: software CDs and DVDs
copyrighted software
Software that prevents a disk from being copied
courseware
educational software
cracking
Unauthorized access and/or vandalism of computer systems; short for criminal hacking
desktop publishing (DTP)
the process or the software used to produce print publications
Examples: posters, magazines, newspapers
digital camera
A camera that stores images as bit patterns on disks or other digital storage media instead of film
digital rights management (DRM)
Technology used in audio files to protect musicians' and other artists' intellectual property.
digital versatile discs (DVD)
Digital video disc or digital versatile disc, a popular type of high-capacity optical disc used in movies and computers.
digitize
to convert info in a digital form in order to store it in a computer
distance education
Using computers, networks, and other technology to allow teachers to educate students at remote distances
distributed computing
Integrating all kinds of computers, from mainframes to PCs, into a single, seamless system.
dots per inch (DPI)
A measurement of the density of pixels, defining the resolution of a graphic.
download
to copy a file from an online source onto your computer
drawing software
stores images as a collection of lines and shapes. also stores shapes as formulas and text as text
drill-and-practice software
Teaching software at an individualized rate, small steps, and positive feedback.
educational simulations
Software that enables students to explore artificial environments and challenge students to learn through exploration, experimentation, and interaction with other students.
ergonomic keyboard
a keyboard that places keys at an angle in order to feel more natural -> reduces repetitious stress-injuries such as carpel tunnel syndrome
ergonomics
science of designing work environments -> people to interact efficiently and safely with things
file compression
reducing the file size -> fit more files into same amount of disk space
file decompression
restoring compressed file back to its original state.
filtering software
Software that, for the most part, keeps offensive and otherwise inappropriate Web content from being viewed by children, on-duty workers, and others.
open-source software
Software that can be distributed and modified freely by users
Linux is the best-known example.
menu-driven interface
User interface allows users to choose commands/pathways from menus
software license
An agreement that allows use of specific software on a machine
