Why does it take so long to download a movie from itunes?
The total time will vary based on one's Internet connection. Movies are of a very high quality and may be easily over one gigabyte in size. Unless one has an Internet connection that costs hundreds of dollars a month like a T1 line, when dealing with gigabytes, it is going to take time.
In Draw to Life how do you get health away from FrostWind?
Once you get past the first part by shooting snowballs at him until you reach the arrows, when you are on the second part when Frostwind comes round you will sometimes get the opputunity do three groudhog jumps(B down B) on him. When you do this, his health will gradually go down so you are able to proceed. The rapo's name you have rescued is Heather.
EDIT: I don't know about the original answerer but on my DS the groundhog jump is A down A. Just thought I should mention it in case B down B doesn't work ^^;

What is the South African fax code?
You dial a fax number on a fax machine exactly the same way you would dial the same number on a landline telephone at the same location.
The telephone country code for South Africa is +27, and you must drop the trunk prefix 0 from the South African area code.
(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
What is a multiplexer and how does it works?
There are many different types of multiplexers. However, the basic function of all of them is to combine multiple signals into a single 'channel' for transmission. At the other end of the channel, a demultiplexor is responsible for splitting the combined signals back into the original, separate signals. Different types of muliplexors include Time Domain (TDM), Frequency Doman (FDM), Statistical (SM), and Space Domain (SDM). In a TDM, for example, every signal is given a specific duration time slice. This means that the bandwidth of the channel between the mulitplexor and demultiplexor (mux and demux for short) must be greater than the sum of the bandwidth of all of the input signals. So, 10 1MHz signals might be multiplexed into on 11MHz signal for transmission across a microwave or fiber link. Much signal transmission equipment is available with the mux functionality built in, freeing the designer from having to worry about it as a separate condition. For example, a fiber transmitter may have several high speed data ports. It senses the bandwidth of each signal, then automatically adjusts its own output bandwidth accordingly. Finally, muxes can be connected to other muxes in a hierarchical configuration. The phone company used such a configuration for long distance traffic, using local loops into groups, into super-groups and so on until satellite bandwidth was reached.
What is the operating system of a computer?
The operating system serves many purposes. Talking at a high level operating system can be cosidered as a translator between user and computer(CPU).CPU or processor can understand only 0s and 1s, but the programs that we use today are written in somehigh level language like C or Java or something else. Now these programs ultimately had to be changed to 0s and 1s inorder to execute. This is the responsibility of Operating System. Then comes multitasking, we can execute multiple programs simultaneously in a single CPU, so this single execution core is shared among programs. This CPU management is also onus of Operating System.Not only CPU managent but many other resources are managed by Operatimg System like memory. Speaking at low level you cannot imagine a computer without Operating System. To facilitate access to the workings of the machine, which at its core only deals in zeros and ones.
Without an operating system, you would have to manually type in instructions to the computer using machine code or a low-level language, and call functions.
It would take several hours to be able to perform simple tasks such as typing word documents!
Operating systems pre-load all the commands, information, and configurations the computer needs to perform tasks automatically, easily, and using a simple interface, such as mouse point-and-click or voice command, as well as streamlining general use and allowing simplified keyboard commands like control-alt-delete
Which is better and iPad or tablet?
It's apples and oranges. one is nothing like the other. The PS3 is a game console that goes in a room connected to a HDTV and has an internet connection so that it can browse the web download movies and play games. An iPad is a portable device that you carry around to use Most people would like to have both and not one or the other.
What programs can you use to separate each vocal and music fom a song?
I think you know sound forge it has a "channel converter" tool for just removing voice approximately. open the sound file in Sound Forge.select the part do u want to remove voice, goto "process menu -> channel converter" a new form will open select the template with a sub name ->Stereo to stereo (vocal cut) from drop down list click ok. This will remove voice. U can also use paragraphic EQ tool to remove voice or beat.
a dulcimer is an Appalachian instrument that you play on your lap it is like a guitar but you simply lay it across your lap, push down the first string (melody string) on a fret and strum all three strings.
Can you put left 4 dead on 2 computers?
Yes, there are some emulators (An emulator is something that lets you play games created by different systems on your computer, well, usually on the computer)
In short, yes.
Is it easy? No, it's a huge game.
Are things like N64 games easy?
I downloaded my N64 emulator easily.
Unless you're willing to pay, then, sorry, you may have some trouble.
What are the pros and cons of the various digital photo frames?
Pros-
-if you have a good camera that you can control the lighting and exposure situation, you'll take incredible pictures.
-photoshop allows you to easily fix small mistakes you might make
-image stabilization on the camera & automatic focus
Cons-
-films cameras can give a much more natural look
-improper use of digital editing will ultimately make the pictures look fake
-almost complete control of the end result image.
-Automatic mode on digital cameras are extremely weak in low lighting situations
How do i know if my car is being tracked by someone?
It all depends on what type of information the device is intended for, for the most parts it's somewhere near the front end of the vehicle, but because of the every changing size and uses of GPS devices it can be anywhere.
Why does the computer use the binary number system?
A computer can only distinguish between two states: on and off. So it can only use two numbers.
Because the first computer consisted of rows of switches which were either on - or off. The binary number system uses a 1 and 0 in place of the on and off functions.
Hello,
The computer uses the binary system because the information in a computer is actually electrical pulses (on/off) And because of that we use 0 (off) and 1 (on) to make it easier for us to calculate it :)
Actually, we don't really have a choice in using the binary system. Computers are electrical machines, so we are pretty much forced to use it as the lowest level of communication. Then past that there's hexadecimal, then plain text.
the computer uses binary number system because the computer can understanding the binary language that is (0,1),and data which are entered by the input device the computer can convert each word into binary number that is (0,1)and then it process the data and again convert into machine language(binary language) to high level language and then we can saw and understand the output result.
Binary is used in all computers because at the hardware level everything is simply on or off, 1 or 0. With only two possible symbols to physically represent, binary systems are extremely simple to implement, whether through mechanical means or through electro-chemical means: a switch is either on or off; a capacitor either holds enough electrical charge or it does not; polarised material is either positively charged or it is negatively charged; a punch card either has a hole at a specific location or it does not. Any medium that can easily differentiate between two possible states can therefore be used to store and retrieve digital data. The simpler the data representation is to implement, the faster the machine will operate. And there simply is no numbering system any simpler than binary.
You can represent 0 and 1 with a simple change of state--on or off. And they can be used to convey the most complex data.
Here's an example. Imagine you have a little box with 4 buttons on it. These are the buttons:
1
2
4
8
If you press a button, it equals that number. If you don't press the button, it equals 0. If you press more than one button, they're added together.
Now look what happens if you press the buttons in different combinations:
no presses = 0
press 1 only, total = 1
press 2 only, total = 2
press 1 + 2, total = 3
press 4 only, total = 4
press 1 + 4, total = 5
press 2 + 4, total = 6
press 1 + 2 + 4, total = 7
press 8, total = 8
press 1 + 8, total = 9
And that is exactly how one "byte" (which contains 8 "bits," each of which can just be on or off) expresses the digits from 0 to 9. And so you can make any number, any number at all, because all numbers consist of the digits from 0 to 9. And you can add, subtract, multiply, divide, and more by turning those buttons or switches on and off.
It gets a little more complicated with letters and special characters (all the symbols you can type that aren't letters and numbers), but the principle is the same.
Along with the data, though, you have to make rules for interpreting it. For instance, you have to make a rule that says the first bit is worth 1, the second 2, and so on. And there are very elaborate rules for how the computer receives, translates, and returns all kinds of data. Those rules are definitions and programs. It even has to have rules for making definitions and programs, and those rules add up to what we call a "language."
You see what we can do with computers. If you're old enough to have watched the possibilities grow over the decades, you are probably more amazed than if you have just grown up with it. And we are really only just beginning. What we have now is still very primitive.
Those 0's and 1's (which we call "binary" and which we can use to mean on/off or yes/no) are incredibly powerful when you combine them with logical reasoning.
How computers use binary codes?
Computers have zero IQ. Computer can understand or feel "High voltage" or "Low voltage" or you can say, on and off. Computers use '0' for low voltage and '1' for high voltage. by using the conbinations of '0' and '1' all numbers and characters are classified. for example- if you have to write 'A', It is represented in ASCII code assigned to it and then converted to binary, hence use it.
There are many ways to make gold in WoW, the main way is by doing quests. Some of the other ways are getting Green, Blue, or Purple items and selling them at the Auction House, doing instances, and getting materials that are needed by the many professions and selling them at the Auction House.
This inventor painter and sculptor sketched ideas for a mechanical adding machine?
Leonardo da Vinci.
Experts mean the sketch does not really show an adding machine, but a ratio machine.
What are some emoticons you can make on the computer?
In the 1970s, "Smiley" was fairly bland: a smile or frown. Most were printed large, such as 8 and 1/2" by 11" sheets as a cheap printing to plaster on telephone poles. Of course, all were bright yellow faces with black features. Later, hair was added but never replaced the original Smiley.
When is the next ben 10 ps2 game released?
Ben 10 Alien Force Vilgax Attacks is released October 27 2009 and October 5 2010
Ben 10: Ultimate Alien was released
Ben 10: Galactic Racing to be released on October 18 2011 will not include the PS2

Key Success Factors
Core Strengths
Apple has numerous internal strengths that make it a successful and
competitive company. For one, Apple has a powerful footing in the personal
computer market by being "different" with its innovative style and ease of use.
Its operating system is developed in house, leaving it free from the tangles of
the dominant Microsoft operating systems. This gives apple a very large degree
of control over its product in the physical appearance, specifications, and overall
usability. Apple does all this while keeping its Macintosh computers compatible
with existing PC computers. Additionally, Apple fosters a research intensive
office environment and is constantly releasing products with the current trends
and styles as seen through its latest iPod and Mac mini. This makes Apple one
of the biggest innovators in the computer and portable music industries, being
first to bring new and creative ideas to the market.
Core Weaknesses
Due to their research intensive nature, Apple has high R&D costs, which
means that Apple is far less cost effective in a very saturated market. While they
currently hold 90% of the portable music market, Apple is constantly relying on
innovation to keep it ahead, putting the company in a risky position if its R&D
does not come through.
Moreover, Apple has a hard time selling the Mac
computer to many customers do to the perception that the Macintosh is
incompatible with other PCs and software. In other words, customers get scared
of an operating system that looks different then windows and assume it doesn't
work the same. While this is not true, it hinders the ability of Apple to steal
away existing PC users to grow its market share.
Finally, Apple has problems
with some customers due to the high prices of many of their products. While
this has not hindered their sales in the portable music market yet, it can be
traced to problems within their computer market sales.
Market Opportunities
Within the industries that Apple competes there are numerous
opportunities for increased market share and growth. Since Apple is already
recognized as one of the main leaders in the portable music market they have
the ability to further increase their company image and quality
image reputation. This will allow Apple to maintain their already
well established clientele as well as attract new customers. Within
the personal computer market Apple is expected to sustain
substantial market share gains in 2005 because customers are
awaiting the launch of Windows Longhorn for Microsoft.
On the portable music side of things, it is speculated that if Apple were to
release a flash-memory based mp3 player that its music business
would be worth close to 5 billion by 2006.
As a final point, many speculate that Apple's entire line of Macintosh computers will gain market share due to the halo effect of the iPod.
Market Threats
There are many potential threats that Apple faces everyday. The primary threat that they face is the rapid advancement in technology. Since most people judge the computer on the speed (GHz) of its CPU, Apple has had a hard time with customers considering the Macintosh inferior in
speed to the PC. Although, recently the new Macintosh
computers have begun using 64bit technology as opposed to the PC which is still primarily using 32bit technology.
This has given Apple a slight edge to their
speed problem. Therefore, Apple must make sure that
they stay up-to-date and on the cutting edge of
advancements and innovations. One slip in their R&D
department and Apple could lose an enormous amount of their market share.
One final note is the threat of Napster, Apple's primary competitor to its iTunes

music service. Napster has begun aggressively marketing its new service which
allows unlimited music downloads which are "rented" to the mp3 unit while the
subscription is active. This service, costing only $14.95 a month, is the first
serious challenge to iTunes 99 cent per song download business strategy.
Whether or not Napster will effectively unseat Apple is yet to be seen, but shows
the vulnerability of Apple's portable music market share.
Competitive Strategy Analysis
In such a highly competitive industry where superior quality and brand
image are key success factors for a computer company, it is necessary for
computer companies to become cost leaders or differentiate themselves by
offering a unique product. Apple has become known as a computer company
that has innovative and stylish computers and music playe
How Are Computers Useful To Human Beings?
With ever increasing availability of more complex and dynamic operating systems, the primary use of a computer is only limited to the imagination and technical know how of the user.
Some examples of use in the home:
- Network attached storage (Linux distribution named FreeNAS)
- Media Server (Hewlett-Packard makes a dedicated version of this)
- Graphics design (Adobe is the forefront in design software)
- Architectural design (AutoCAD leads this category)
- On-line banking (savings, loans, insurance, credit, mutual funds...)
- Gaming (always fun, sometimes aggravating)
- Social Networking (Myspace, Facebook, Twitter).
- Knowledge sharing (WikiAnswers, Wikipedia, Lifehacker, Gizmodo)
- Science (Folding at Home is a great example of home-based cloud computing)
The list goes on. These are just a few examples. Use your imagination, and chances are someone is using a computer in their home somewhere for that purpose.
