Question 1

What is the difference between an algorithm and a protocol?

Accepted Answer

A protocol determines not only what needs to happen but also who is responsible for making it happen. For example, a recipe might tell you how to bake a cake, but a protocol also determines who is responsible for buying the ingredients, mixing the batter and so forth.

Question 2

What computer network is generally considered to be the origin of the Internet?

Accepted Answer

ARPANET is generally considered to be the origin of the Internet. ARPANET was a network created by the US Department of Defense that connected universities and private research facilities that were working on ARPA (Advanced Research Project Agency) related contracts.

Question 3

Which of the following equations is used for evaluating a retaining structure's factor of safety of against overturning (FS_o)?

Accepted Answer

The equation FS_o = resisting moment / overturning moment is used for evaluating a retaining structure's factor of safety with respect to overturning. Typically, a minimum factor of safety of 2.0 to 3.0 is considered necessary for a retaining wall to resist rotating outward around the toe of the wall. FS_o is expressed as follows: FS_o = ?Mr / ?Mo Where ?Mr is the sum of the resisting moments around the toe and ?Mo is the sum of the overturning moments around the toe

Question 4

What is a white-hat hacker?

Accepted Answer

White-hat hackers expose security vulnerabilities so that they can be fixed. These activities are sometimes, though not necessarily, illegal or controversial. Black-hat hackers exploit security vulnerabilities for personal gain.

Question 5

1. Parenthesis: 323 + 543 x (45.3 + 33.6) / 22 -17
= 323 + 543 x 78.9 / 22 -17
2. Multiplication: 323 + 543 x 78.9 / 22 -17
= 323 + 42,842.7 / 22 -17
3. Division: 323 + 42,842.7 / 22 -17
= 323 + 1,947.4 -17
4. Addition: 323 + 1,947.4 -17
= 2,270.4 - 17
5. Subtraction: 2,270.4 - 17
= 2,253.4

Question 11

At what height above the Earth's surface do Global Positioning System satellites orbit?

Accepted Answer

Global Positioning System satellites orbit at approximately 20,200 km above the Earth's surface. The mean Earth radius is approximately 6,360 km and the mean distance of a GPS satellite's orbit to the middle of the earth is 25,560 km. Geostationary satellites typically orbit the earth at approximately 42,300 km.

Question 12

What is the most important consideration when developing high quality field notes?

Accepted Answer

Accuracy, legibility and integrity are all important considerations when developing high quality field notes.
If the angles, distances and field note entries are not correct, the entire survey was a waste of time. All measurements and survey details must be recorded at the time of observation and should never be altered in order to yield a perfect closing. If the notes cannot be read, they are meaningless. Additionally, survey information is of little value if the notes are not complete and clear.

Question 13

Leveling (in surveying) is used to determine which of the following:

Accepted Answer

In surveying, leveling is used to determine the difference in elevation between points on the Earth's surface. Vertical measurements are made and expressed as elevations referenced to datums. There are three methods used to determine differences in elevation: direct vertical measurement; trigonometric leveling; and differential leveling.

Question 14

What does the term "metadata" mean as related to spatial data?

Accepted Answer

The term "metadata" as related to spatial data is the information that describes the content, quality, origin or other characteristics of specific pieces of data.
Metadata describes and documents data, providing GIS users with the details on how, when, where and by whom the data was collected; the source of the data entered into the GIS; data projection, scale, resolution and/or accuracy; and the reliability standard to which it is measured.

Question 15

The final measurement in the line of tapes is 83 ft. The normal tape tension is 10 lbs. for the 100-ft tape used. What amount of tension should be applied to the spring balance of the end of the tape to yield the proper tension to the 83-ft increment?

Accepted Answer

8.3 lbs. of tension should be applied to the 83-ft increment of tape.
Solution
10 lbs. /100 ft = 0.1 lb. /ft
(0.1 lb. /ft)(83 ft) = 8.3 lb.

Question 16

In an area where the Earth's surface is higher than the geoid, which of the following statements is true?

Accepted Answer

In an area where the Earth's surface is higher than the geoid, the area is probably located in a mountainous region or on a high plateau. As the geoid is the equipotential surface that best fits mean sea level in a least squares sense, an area that is significantly higher than the geoid is probably in a mountainous region.

Question 17

What activity reduces huge amounts of data to smaller sets of meaningful, usable data?

Accepted Answer

Data mining is the act of reducing huge amounts of data into usable pieces of information. This is mostly done by eliminating data that isn't interesting and looking for patterns in the rest. These patterns, as opposed to the data that underlie the patterns, are often actionable.

What is the firm's approximate facility capital cost of money (FCCM) on a direct labor basis?ItemItem Cost ($)Cost ($) Item Cost ($) Direct LaborDirect Labor 6,234,6686,234,668 Direct Labor 6,234,668 Allowable fringe benefitsAllowable fringe benefits 3,233,8893,233,889 Allowable fringe benefits 3,233,889 Allowable general overheadAllowable general overhead 8,444,4448,444,444 Allowable general overhead 8,444,444 Facility cost of capital (FCCM)Facility cost of capital (FCCM) 190,000 190,000 Facility cost of capital (FCCM) 190,000

Accepted Answer

The firm's approximate facility capital cost of money (FCCM) on a direct labor basis is 3.0%.
Solution
Determine the ratio of the facilities capital cost to the cost of direct labor.
FCCM rate = FCCM/direct labor cost
= ($190,000)/($6,234,668)
= 0.03 (3.0%)
