What kind of method is applied to all objects of a class rather than individual?
A class static method can be applied to all objects of a class.
What is means by biometric input?
Biometric input is a fed in by a device designed to measure certain physical qualities, such as facial recognition, fingerprint recognition, handprint recognition, or any other type of system that can reasonably identify one person from the rest of the people living in the world, and often replaces or supplements traditional passwords.
How do you open inc. file extensions?
INC file extensions usually indicate that they are "include" files (i.e. they are written with the intent to being called from another source code file). These files are opened using any normal text editor, such as Notepad, Vi, or Edit. Special editors also exist for the language that the source code within is written in, and typically includes auto-completion, syntax highlighting, and error checking.
How do you turn a computer image into a poster?
first save the picture, (dont kow if this works)
and then when you are printing select the size you want. (make sure it is in color)
How do you obtain a tcsh shell login on mac?
If requested for a login it will be the standard Admin user name and password for that account. If you mean how do you open tcsh instead of the default bash you need to open Terminal (in the Utilities folder within the Applications folder), select Preferences from the Terminal menu, select the Startup option and change the Shells open with: option from the default to Command and set the path to /bin/tcsh Close the Preferences window and Quit Terminal. When you launch Terminal it will use tcsh.
Why all variables are declared with in the function?
It is not necessary to to declare variables inside the function in C. If you declare a variable inside a function, the variable becomes local for the function and another variable of same name can be declared in any other function, but you can not use the variable declared in other function. When you declare any variable outside the function body then the variable becomes global and can be used in any function of the program.
Note: errno is an example for a variable declared outside any function.
Can two compilers from different language share components. how?
The lexical scanner is one of the good candidate to be shared among different compilers. The breakdown of tokens should be the same, or at least similar. However, the interpretation of those tokens will be different between languages. The storage of those tokens, stacks, or hash tables, can be the same as well (reusable component).
What is the difference between BIT and Bcs Degree?
Hi: I am form Afghanistan:
my ask about the BCS/BIT
which one is best for the and which subject studying in BCS
and which subject studying in the BIT
thing
How do you locate a fraction and decimals on a number line?
On a number line used to illustrate values in the study of math, integers or whole numbers are spaced evenly, and fractions are in between the whole numbers. Positive nubmers are to the right of zero and negative to the left.
On the positive side, a fraction is placed to the right of the next smaller and to the left of the next larger whole number. It doesn't matter whether you are representing fractions as common fractions (as 5/8 for five eighths) or decimals (as .625). Either way, this number would be to the right of zero and do the left of one. 17.4 would be between 17 and 18.
What is 7777777777777777777777 plus 8888888888888888888888888888888?

KBstatusLED.exe is regarded as malware. Although it resides in the Windows folder, it is not part of Windows. Anything that installs itself into the Windows folders should be treated with suspicion. Unininstall it.

What is the difference between advanced encryption algorithm and encryption algorithm?
People have developed many encryption algorithms.
One particular encryption algorithm is the Rijndael algorithm, usually called the AES or Advanced Encryption Standard.
How do you turn off parent controls?
Parental controls can often be accessed in the options/tools menu of the system. However, to successfully disable parental controls, the pin number may be required.
What are the two applications of dynamic programming?
1)Multistage graph
2)Travelling salesman problem
Can open source software be virus ridden?
It's not impossible, but it's unlikely. Since anyone can see the code, it is likely someone would discover any viruses someone would attempt to put in there, and they would quickly be found out and discovered.
What is a good sentence for compile?
Example sentence - I will compile the details for the report once I have all of the facts.
In computer programming or text markup, to hardcode (less frequently, hard code ) is to use an explicit rather than a symbolic name for something that is likely to change at a later time. Such coding is sometimes known as hardcode (noun) and it is more difficult to change if it later becomes necessary. In most programming languages, it is possible to equate a symbol with a particular name (which may also represent a number) value
In computer science and graph theory, the method of color-coding efficiently finds k-vertex simple paths, k-vertex cycles, and other small subgraphs within a given graph using probabilistic algorithms, which can then be derandomized and turned into deterministic algorithms. This method shows that many subcases of the subgraph isomorphism problem (an NP-complete problem) can in fact be solved in polynomial time.
In general Color coding,
A color code is a system for displaying information by using different colors. Color codes are often difficult for color blind and blind people to interpret.
The earliest examples of color codes in use are for long distance communication by use of flags, as in semaphore communication.The United Kingdom adopted a color code scheme for such communication wherein red signified danger and white signified safety, with other colors having similar assignments of meaning.
As chemistry and other technologies advanced, it became expedient to use coloration as a signal for telling apart things that would otherwise be confusingly similar, such as wiring in electrical and electronic devices, and pharmaceutical pills.
The use of color codes has been extended to abstractions, such as the Homeland Security Advisory System color code in the United States. Similarly, hospital emergency codes often incorporate colors (such as the widely used "Code Blue" indicating a cardiac arrest), although they may also include numbers, and may not conform to a uniform standard.
