- Answer-true
The term for information that can be represented by a finite alphabet of symbols, such
as the numbers 0 through 9 or the symbols represented on a computer keyboard, is
data. - Answer-true
What character set in use today is the most common format for English-language text
files? - Answer-ASCII
Industry experts estimate that approximately 15 petabytes (15,000 gigabytes) of new
electronic data are created every day, much of this the result of huge growth in video,
image, audio, and social media data. - Answer-true
Examples of image-based applications used by businesses include: - Answer-digital
photographs, electronic publishing, web publishing, medical publishing
A page of text contains about 10,000 bits of 8-bit character data. The bit image of a
640x480 pixel screen in 256 color mode requires over: - Answer-two million bits
What approximate data rate would be required, without compression, to send a
resolution of 360x250 pixels with an 8-bit grayscale color palette? - Answer-25 Mbs
In terms of the networking implications of video information, real-time video traffic
without compression requires minimal bandwidth to ensure an adequate user
experience. - Answer-false
Since the 1970s, computer communication has changed from an esoteric research topic
to an essential part of everyone's lives. - Answer-true
In 1980, the Internet was a research project that involved: - Answer-less than 100 sites
Today, the Internet has grown into a production communication system that reaches all
populated countries in the world. - Answer-true
Lack of consistency in the networking field has produced a challenge - instead of
uniform terminology, multiple groups each attempt to create their own terminology,
, resulting in jargon that contains terms that are abbreviated, misused, or associated with
products. - Answer-true
The network services and facilities that users interact with are provided by each
individual user. - Answer-false
Data communications is the study of using physical phenomena to transfer information
across a physical communication... - Answer-medium

Network technologies are created to meet various requirements for: - Answer-economic
cost, distance, speed
In the 1970s, the Internet was: - Answer-proposed by Cerf and Kahn, a set of
standards, a revolution in computer networking, a concept
One of the primary reasons for the success of TCP/IP standards lies in tolerance of
homogeneity. - Answer-false
Because the Internet tolerates heterogeneity, engineers can experiment with new
networking technologies without disrupting existing networks. - Answer-true
The term protocol refers to a specification for network communications. - Answer-true
Multiple protocols designed to work together in a complete, cooperative set are called a
suite. - Answer-true
Protocols in a suite are furthermore collected into a unified whole known as a layering
model. - Answer-true
Protocol implementations follow the layering model by passing the input from a protocol
in one layer to the output of a protocol in the next layer. - Answer-false
A pair of protocols in adjacent layers pass a pointer to the packet rather than create a
new copy. - Answer-true
As data passes down through the protocol layers on the sending computer, postage is
added. - Answer-false
What entity created the Open Systems Interconnection (OSI) seven-layer model? -
Answer-ISO (International Organization for Standardization)
