Why an odd-degree function must always have at least one real root?
An odd-degree function approaches positive infinity in one direction and negative infinity in the other direction so the graph must cross the x-axis at least once, giving it at least one real root.
What is the range of 64 76 46 88 88 43 99 50 55?
that's simple...
the highest number: 99
minus the lowest number: 43
99-43=56
How do you write a program that outputs a given characters in reverse?
write the javascript code to display the reverse no. of given no. (e.g. 247 reverse of 742)
What is the difference between a process and thread?
The same metaphor: the difference of a person (thread) and a family (process)
A process has at least 1 thread and may have many threads, while 1 thread must live within a process
Is wanting to become a computer hacker bad?
It depends on what you mean by hacker.
Being a true hacker is someone who knows lots about a particular technology and is good at modifying it to make it better. Whether hacking is a good or bad thing depend on what you hack. If you hack some thing with a copyright or cause destruction then yes it is bad. If you use those skills to improve open source software, do legal penetration testing, digitalize a toaster, build your own chat program, ect. then hacking is a good, legal, and fun hobby or possibly even a profession.

It is a program that is used to view .vpe files, which are virtual print engine files. They are rare but are used by some, for me I received a receipt from a courthouse in .vpe format and had to download a VPE file viewer to open it, see it, and print it.
How do you program with .dlls?
Introduction to DLLs......
DLLS as the name suggests are the Dynamic Linked Libraries, majorly comprises of the Classes (inclusive of Constructors, Procudures and Function) in case of Object Oriented Paradigm, and / or procedures / functions in case of Procedural Language, are basically used to provide a Service / serve the Application in question!!!
Towards the Question ......
DLLs cannot be executed directly rather its been made call by any of the Application running. So while Designing an Application, the Dlls are either imported or rather is refered to/by the application program.
For Example :-
In VB.NET the syntax for importing a DLL to an application is as below
imports somedll.
In C#.NET the sysntax is
using somedll;
where "somedll" is a dll file name (somedll.dll)that has been imported from the Computer's HDD mem0ry.
Based on this import of dlls we create either an object or directly make a function call located in that DLL file, like here it is somedll.dll...........
What tasks can be accomplished using Task Manager?
When using task manager, it can turn off programs that locked up.
like enternet explorer, or windows media player.
Value of automatic variable that is declared but not intialized?
The value of an automatic variable that is declared but not initialized is indeterminate.
Some debug implementations will preset uninitialized variables to a known state, such as 0xcccccccc, or my favorite, 0xcacacaca, but that is just a hint that you are doing something very, very wrong if you ever encounter such a value.
What is the purpose of a system call?
System calls are used whenever a program needs to access a restricted resource, eg a file on the hard disk, any hardware device, or when it needs to print or draw to the screen
Difference between in-system programming and in-application programming?
simple , In system/circuit Programming [ISP/ICP] is process with which entire on chip controller flash is programmed, where as In application Programming [IAP] is scheme in which a running program - re-programs controller flash by receiving new .hex file from any of the serial interface.
Advantage and distadvantage in hash table?
ANSWER A hash table is a way to find data in an array, when you have a known key and an unknown value that corresponds to the key. You use a hashing function on the key to create an index into the hash table containing the value. In the ideal case, this directly returns the corresponding value. In the usual case, a collision can occur. This means that the hashed key points to multiple possible values. A hash table is usually used on large arrays that would take a long time to search using other methods. A hash table can be very fast and use very little memory, and does not require the array to be sorted. The source code is slightly more complicated than some search methods. With a poorly designed hashing function when the hashed keys do not correspond one-to-one with the values, the secondary search after a hash collision can take a large amount of time.
What assembly language directive indicates the start of the code segment?
The "ORG" (for "origin") statement indicates the start of the code segment.
Many assembly language source files start with "ORG 0", indicating that instructions begin at address 0.
Many other assembly language source files, such as COM files, start with "ORG 0x100", indicating that instructions begin at address 0x100.
Compare multi-core and dual core?
"Dual core" implies that there are two separate instruction execution units placed on a single "die." Some use shared components, such as cache, while others have two full processors, including all sub-components. All dual core processors could be considered multi-core (which simply means multiple "cores" or "processors"). However, a tri-core or quad-core is also a multi-core. Therefore, all dual cores are multi-cores, but not all multi-cores are dual cores.
What is the difference between catch exception e catch error err and catch throwable t?
In Java it is related to the class hierarchy of exceptions. Throwable is the root object of the heirarchy, and both Exception and RuntimeError subclass it. Methods include a "throws" clause in their signature to indicate errors of type "Exception" that can be thrown in the body of the method and returned to the caller. Errors of type RuntimeError do not need to be reported in the throws clause.
Exceptions are also called "checked" errors, and RuntimeErrors are called "unchecked." This simply means that methods that throw checked errors must declare them in the signature.
* Exception: this is a "checked" error. Usually, this is some sort of data error that can be handled by the method. An example is FileNotFoundException - some code didn't an expected file, but the program may be perfectly capable of going on.
* Error: A more serious problem that a program probably can't deal with. An example is OutOfMemoryError - when there is no more memory, there isn't much you can do about it and not much point in continuing.
* Throwable: Superclass of both Error and Exception.
So the main difference is that
* 'catch Exception' will catch just exceptions (the problems you might deal with)
* 'catch RuntimeError' will catch just errors (the problems you probably can't deal with)
* 'catch Throwable' will catch all errors.
Generally, you want to catch Exception or Throwable, but not RuntimeError. You will only want to catch Throwable if there is a requirement that the method never throw an error back to the caller.
See related link to the Java API, and browse the documentation and subclasses of Throwable.

What do you enter for a question on excel?
In Excel, you enter a question or any text into a cell by simply selecting the cell and typing your query directly. If you want to perform calculations or functions based on that question, you may need to use specific formulas or functions in the cell. For example, you could use the =IF() function to evaluate conditions based on the question posed. Always remember to start formulas with an equal sign (=) to indicate that you're entering a formula rather than just text.
