When you press the no 4 button in keyboard it will prompt control pannel and printer icon and default printer?

Answer

I read your question and tried it on my computer, nothing happened, perhaps there is something wrong with your computer in the programming section. If this isn't a problem for you just leave it, but if it's a problem take your computer to a computer store and ask them what the problem could be.

What is the Purpose for ripping music when adding to computer?

'Ripping' is the generalized term used for copying tracks from a CD to the PC's permanent drive. The purpose or need for this is to categorize the songs or tracks you want to duplicate onto another medium like an iPod, CD, etc.

'Burning' is the term for creating a CD-R or CD-RW disk.

Can a computer have two operating systems?

Yes,

Windows and Linux can be on the same machine. You have to look at Linux FAQ's to determine which to install first as I don't remember. The point is that it isn't difficult and it isn't crazy.

To switch the machine has to be rebooted. There was an effort to have an emulator under Linux (e.g. WINE) to run a windows session in a Linux window. I don't know the status but you take a performance hit

There are commercial products for running different OS's from within Windows, do a google search. These are availablke for the MacOS as well

The latest versiuon of OSX is claimed to be able to run windows as a built in feature. Go to apple.com to find out

good luck

How do you pre-program a PC to record radio programs similar to video pre-programming for television?

First, you have to have a way for your PC to capture the Radio signal, such as a card or USB device built especially for that purpose. I have a TV Tuner card that has an FM tuner built in. With that I'm able to set up recording of TV and radio automatically. If you do a lookup on Winfast tv2000XP pro. that's the card I have.

What are the four distinct reasons when new processes might be created?

1 reasons for creating multiple processes is 1- If in an application there are various independent major operations, we can create multiple processes for these tasks, a perfect example of this is operating system When you issue the execve or fork syscalls a new process is created. (spawning an application is eseentialy fork + execve) Processes are also created by the kernel scheduler for various internal tasks :P

How 'free' works in c language if you want to free a structure whose elements are itself pointers?

Assuming that the structure you want to free points to OTHER structures that have been malloc'ed, you need to free any malloc'ed elements that are pointeed to by the elements in your structure. Doing otherwise will result in a memory leak. As you free the elements of the structure, make sure that the pointers are NULL, then you should be able to free the structure. If you're doing all this in a UNIX like environment, all memory structures will be freed when the application ends. If you're doing it in a Windows environment, all bets are off.

What is difference between manifest and meta data?

menifest also reffered to as assembly metadata(data about data),contains all information related to assembly like identity section,version number,strong name (optional),culture.so menifest contains information related to the identification assembly or it is a part of assembly where assembly is self describing.

metadata is the information that enables components to be self describing.it is used to describe which class is used,function,methods,fields ....So it is the data about data.

What is linear data structure?

when elements are accesed or placed in contiguous memory location yhen data structure is known as linear data structure. stacks, arrays, queues and linklists are example of data structure.

in non-linear data structure element are not placed in sequential manner. trees, graph are the ex. of non-linear data structure.

How to translate the coordinates of a point?

Here's an example:

In the coordinate plane, the point is translated to the point . Under the same translation, the points and are translated to and , respectively. What are the coordinates of and ?

Any translation sends a point to a point .

For the point in the problem, we have the following. So we have . Solving for and , we get and .

So the translation is unit to the right and units up. See Figure 1. We can now find and .

They come from the same translation: unit to the right and units up. The three points and their translations are shown in Figure 2.

Why are modern operating systems designed to implement multiprocessing?

Multiprocessing is based on the fact that computers work much faster than humans. While you type a sentence on your word processor, the computer is doing nothing, waiting for you to hit the 'save' key, or the spellchecker. Because many people want to do as many things at the same time as possible, modern operating systems are designed to be able to have several programs working at the same time. Thus, while a person is surfing the Web, their email program is checking for new mail. Macintosh was the first multitasking operating system for home computers, followed shortly by Windows. Every window that is open in Windows is a separate application as far as the central processer is concerned, and each one is given a certain amount of processer time to perform whatever processing is needed.

Until recently, the processers in home computers were not fast enough to be able to multitask without a noticable slowing down of the applications. Playing a CD while accessing the hard drive resulted in choppy audio, and slow refresh times on the moniter. However, new proccesers are so fast that many different applications have to be active before any noticable slowdown occurs.

What are the best ways to learn about other cultures?

The best way to learn about other cultures is to immerse yourself in the culture. Move there, live there, learn the language(s) and experience the every day over an extended period of time. The above is true, but if you aren't financially able to do this then read everything you can on different cultures or at least one in particular you are interested in. Also choose friends of different cultures and you can learn some of their traditions and they can learn yours. Variety is everything in friendships.

What is a logical disciplined approach to programming?

Use Software Engineering techniques, specifically UML, to design the structure of the program before-hand. Then you know how different classes within the program (assuming you are using an Object-Oriented approach) need to communicate with each other, and you've broken the whole program down into the smaller more manageable chunks that need to be written.

What is meant by a thread in java programming language?

A thread and a process are same but a minor difference is there.

Process executes a program completely without splitting whereas a thread splits a program into smaller tasks and then execute them separately.And then combine the final result.

that is why a process is often called as Heavy weight and a thread is called as light weight.

Which is better encryption algorithm among DES Blowfish and MD5?

MD5 isn't a encryption algorithm, it's a hashing algorithm.

Encryption will 'hide' the meaning of the encrypted text, while MD5 will 'add up' all the text to come up with a number. This number can be compared to another time this file was 'added up', to provide a simple kind of check to see if the text has been changed or if it is the same.
