ANSWERS (VERIFIED ANSWERS) ALREADY GRADED A+
Digital Revolution Ans✓✓✓an ongoing process of social, political, and
economic change brought about by digital technology, such as
microchips, computers, and the Internet.
Convergence: Ans✓✓✓process by which several technologies with
distinct functionalities evolve to form a single product
The Web Ans✓✓✓a collection of linked documents, graphics, and audio
that can be accessed over the Internet.
Cloud Computing Ans✓✓✓provided access to information,
applications, communications, and storage over the Interne
Bits vs. Bytes Ans✓✓✓the word bit is an abbreviation for binary digit, it
can be further abbreviated, usually as a lowercase b. A group of eight
bits is called a byte and is usually abbreviated as an uppercase B
Digital vs. Analog Data Ans✓✓✓Digital data is text, numbers, graphics,
sound, and video that have been converted into discrete digits such as 0s
and 1s. In contrast, analog data is represented using an infinite scale of
values.
Digitization Ans✓✓✓The process of converting information, such as
text, numbers, photos, or music, into digital data
,Lossy Compression Ans✓✓✓throws away some of the original data
during the compression process.
Lossless Compression Ans✓✓✓provides a way to compress data and
reconstitute it into its original state.
Image Resolution vs. Aspect Ratio Ans✓✓✓the proportional relation
between the width and height of an image or video frame. Video
resolutions can be expressed as width × height,
Pixel Interpolation Ans✓✓✓A process that is used by graphics software
to average the color of adjacent pixels in an image, usually when the
image is enlarged.
Audio Sampling Rate Ans✓✓✓refers to the number of times per second
that a sound is measured during the recording process
Data vs. Information Ans✓✓✓data is used by machines, such as
computers; information is used by humans.
Bitmap vs. Vector Graphics Ans✓✓✓consists of a set of instructions for
creating a picture
, File Size Ans✓✓✓Vector graphics usually require less storage space
than bitmaps.
Easy of Editing Ans✓✓✓It is easier to edit an object in a vector graphic
than an object in a bitmap graphic.
Resizing Ans✓✓✓Vector graphics resize better than bitmaps
Realism Ans✓✓✓• Vector graphics are not usually as realistic as bitmap
images.
3-D Graphics Ans✓✓✓are based on vectors stored as a set of
instructions describing the coordinates for lines and shapes in a three-
dimensional space.
Vectors Ans✓✓✓The vectors form a wireframe that acts in much the
same way as the framework of a pop-up tent.
Rending Ans✓✓✓The process of covering a wireframe with surface
color and texture
Ray Tracing Ans✓✓✓The technique for adding light and shadows to a
3-D image
