What is constant variables?

Variables are items, which change their values during the execution of a program.

Constants do not change the value during the execution of a program.

Give an example of quantitative data?

Quantitative data deals with numbers. It is data that can be measured. An example of this is: 51% of the world's population is female.

Can polygons be 3D?

No. That would make them a prism.

* * * * *

No. A polygon is a 2-dimensional object ad so cannot be 3-d.

Also, there is no need for the shape to become a prism, as suggested by the previous answer.

What is the advantages of automated car parking system using microcontroller?

you dont need round the clock attendants or valets

you tend to need more expensive labor to fix the machines tho

these can be part timers since we have cell phones now

possibly cheaper than live parking attendants but response time is a LOT slower

Where can you find a CAD drawing of a Supra?

the TAMIYA 1:24 Supra comes with orthographic drawings of the Supra-- (left, top, front, back views)... that's the most accurate drawing out there that I've seen, but can't help you with the CAD drawings.

Can the contrast agents used during computed tomography scans be dangerous?

Contrast agents are often used in CT exams and the use of these agents should be discussed with the medical professional prior to the procedure. Patients should be asked to sign a consent form concerning the administration of contrast.

18 Suppose you work for a telecommunications carrier who is looking into providing WiMAX in a suburb of a large city A colleague suggests that your company reserve licensed frequencies from the FCC?

Good luck !

-- Those frequencies are being auctioned now, raking in $erious buck$ for the govt. Like in the billion$ !

-- Once a license is granted, there is a time limit within which you must use it, i.e. put something

up on the air on the assigned frequency, otherwise the license lapses and you no longer own

the frequency.

Why does the television need to be connected to the isolation transformer before it is connected to the power source?

Television sets do not need to be connected to isolation transformers for normal operation. However, most modern sets do not have power transformers, which means they run directly off of the line. In that case, you do need an isolation transformer to protect yourself from electrocution during repair.

How much is CAD?

it is one hundred forty eight dollars and twenty one cents

I have a assignment to do and i need to know some CAD programs and explain what they do and why they are goodbad. can anyone helpwhat are some CAD programs?

Auto cad is a kind of aplication software programme which make the people to draw different kinds of drawing for eg. architecture drawings, fire fighting drawings , furniture drawings ,mechine drawinngs ,electrical drawings etc. In past when autocad programmeswas not developped that time also people was working by hand scatching drawings but nowadays it is impposible from hand because in past people was made low level building but now people are making high rising building. Without auto cad we did not got accuracy so for good accuracy we must have to use auto cad programmes. 2D CAD now is a commodity you can get it free from almost every vendor. Almost all today's CAD vendor flagship now is a 3D cad with advance feature like standard ecomponent library, rendering, parametric designing and collaboration. Another feature usually bundled is the stress analysis and specific function like fluid/pumbling analysis.

Autodesk's 3d product now is called Inventor with competitor among others are : solid works and solidegde. They are more or less equal in quality so best way to buy is have them demonstrate and provide trial version for you to try out. Last but not least beware of the maintenance scheme. It could get quite expensive.

What are the disadvantages of RoundRobin Scheduling?

Pure round robin scheduling processes A, then B, then C, then starts at A again. (A, B, C might be tasks in an operating system context, or devices in a master/slave control network, or whatever.) That is, pure round robin scheduling doesn't acknowledge priorities, and does not allow out-of-order processing. Real-life systems typically use a mixture of algorithms that, together, allow for prioritized and out-of-order processing while, on the other hand, trying to prevent starvation of lower priority items.

Definition of auto in autocad?

The term "autocad" is frequently used to refer to any type of computer aided drafting (CAD), however AutoCAD is actually the trademarked name of the CAD software produced by a company called Autodesk. The "Auto" in AutoCAD doesn't mean anything, but is just a reference to the company's name.

What is the meaning of constant variables?

Constant variables are variables that, once initialized, do not change in value. They are effectively the same as literal constants, except that you can use symbolic names to make it easier to understand the meaning of the program.

For instance, in a trigonometry program, it is easier to use the identifier PI than it is to use the literal 3.1415926535897932. Also, if you have a constant that might be adjustable, such as a factor in an equation, naming it allows you to change its value by changing only one line of code, rather than seeking out all of the lines of code that refer to the factor.

Constant variables are also candidates for being placed in read-only memory, potentially making the program more secure.
