What is meant by the phrase 'language independent' when talking about pseudo-code?
Pseudo-code is intended to be easily understood by all programmers regardless of the programming language they use. Pseudo-code is not a programming language, it's merely a way of generalising an algorithm in a program-like manner such that the semantics of the algorithm can be easily digested and converted into any language-dependant code. There is no "standard" that dictates the syntax of pseudo-code, thus it is often much more verbose than an actual programming language would be and is typically heavily commented to cater for languages that do not permit ideas to be expressed directly in code. This ensures that the same code can be utilised by any programmer, hence it is language-independent.
What do the computer words Ram and Rom stand for?
"RANDOM ACCESS MEMORY
Data is loaded into RAM from long-term storage (ie- the hard-disk drive) for execution/processing by the CPU. Having too little RAM can lead to performance problems as data is paged back to the hard drive in order to make space for data that is being loaded into RAM."
"ROM = Read Only Memory. Though a CD-R can be written to, generally, it's only once. Then the CD can only be read and being a form of memory, can be called ROM or CDROM when applied to a CD. All music CDs are basically ROM. Even an LP record could be considered a form of ROM as its content cannot be changed. But in general, ROM refers to electronic devices"
What are the application programs and the operating system programs?
Application programs - they are designed to perform specific tasks. Widely used application programs include:- *Word processing
*Spread sheet programs
*Data base progrms
*Graphics programs
*Accounting programs
*Utility Programs Norton Utility
Operating System- they are a set of instructions that enables the computer hardware and software to interact.
Who invented Mac operating system?
The Mac's operating system has evolved over several decades with contributions from numerous software engineers and designers at Apple.
If the application programmer believes it is important for 1 bit to be stored in the Windows Register then it will be done. Usually it is not needed.
Converting video from MSWMM to avi?

Enumerated goods were products/goods produced by the colonies that could only be shipped to England.
What is the profit and loss of obeject oriented programming language over structured programming?
Usually when dealing with object oriented code you have a loss of efficiency, but you have the ability to reuse your code. I also find the time that it takes to design the application is more when your using OO.
Difference between a user control and a custom control?
In Windows programming, both user control and custom control refer to a control. Controls are re-usable components that may, but don't necessesarily do, have a graphical user interface. In some development scenarios, controls can be added to the application's graphical user interface using a simple drag-and-drop operation.
The term "user control" refers to a standard control that may be used by the user (the programmer). Perhaps the name would have better been "standard control." User controls include pre-defined components for all the fundamental components of a Windows graphical user interface, such as buttons, sliders, check boxes, radio buttons, lists and drop downs, etc. Non-interactive components such as a simple timer interface are also included.
A custom control is a control that is especially made by the programmer, and is not included with the development toolkit as a pre-defined component.
Is an Intel Celeron processor a dual core processor?
There are Celeron dual core processors today. However, just because you have Celeron processor, it does not mean your Celeron processor is a dual core processor. The easiest way to tell is to look at the Intel sticker on your computer. If it says "Dual Core," then it is dual core. If it does NOT say "Dual Core," then it is not dual core.
The Native Image Generator (Ngen.exe) is a tool that improves the performance of managed applications. Ngen.exe creates native images, which are files containing compiled processor-specific machine code, and installs them into the native image cache on the local computer. The runtime can use native images from the cache instead using the just-in-time (JIT) compiler to compile the original assembly.
Differences between walkthrough and inspection?
Walk through is an informal meeting for evaluation. No preparation is required Inspection is a methog that deserves careful consideration by an organizatin concerned with the quality of the product. It is conducted by quality control members.

How do you fix your computer of it doesn't always go through the boot phase?
It depends on what type of computer and what you mean by Boot Phase. All PC's go through a POST check (power on self test). This powers up the hardware and checks the mother board components: hard drive, processor, memory etc. If a component is faulty it might prevent the boot sequence continuing. Check your BIOS for a diagnostic tool, some PC's have self test option if you press a particular key to interrupt the boot sequence.
If it is Windows that is not loading first thing to try is press F8 as soon as Windows loads. Choose Safe mode and see if it boots. Safe mode is where Windows loads but only with the minimum of software and hardware support. If the PC can't boot to Safe Mode try to do a repair using your Windows disk (installation CD or DVD). For XP run through the setup wizard and do not choose repair until the setup program finds there is an existing install, then choose to repair it, there are plenty of guides on repairing different version of Windows on Microsofts website.
The third alternative is to boot from a Windows PE disk. These Windows "Preinstallation Environment" disks can be easily downloaded and are free. They load a stripped down version of Windows from CD and can be used to look at various system logs, registry, files and folders on the host PC. They can also be used to reset passwords on machines where the local admin account password is lost. Barts PE is my favorite for XP although there are plenty going around.
What is the definition of an open source distribution?
Distribution is a word usually used to refer to a certain version or "flavor" of UNIX or Linux, and open source is code that is free to modify and recompile, distributed in source code form (and usually precompiled binaries, as well). Most open source software is available free of charge, but not all of it. So an "open source distribution" would be a certain version of UNIX or Linux that is free to modify and recompile, distributed in source code form. All Linux distributions are required to be open source, as they are all under the GNU General Public License, which you may read at the following address: http://www.gnu.org/licenses/gpl.html
Difference between the first generation language and third generation language?
Released on January 11, 2005, the first-generation iPod Shuffle weighed 0.78 ounces (22 g) and was designed to be easily loaded with a selection of songs and to play them in random order. According to Apple,[citation needed] owners of existing iPods had often left the music selection to "shuffle", and the new iPod Shuffle was a way of implementing that in a much more cost-effective fashion. It relies on the use of an "autofill" feature in iTunes, which can select songs at random from a user's music library (or from a specific playlist) and copy as many as will fit into the iPod Shuffle's memory. The Shuffle can hold up to 240 songs (1-GB model, based on Apple's estimate, of four minutes per song and 128 kbit/sAACencoding). It used the SigmaTelSTMP35xx system on a chip (SOC) and its software development kit (SDK) v2.6, a flash memory IC, and USB rechargeable lithium cell. The STMP35xx SOC and its software was the most fully integrated portable MP3 playback system at release time and SigmaTel was Austin's largest IPO (2003) capturing over 60% of flash based MP3 player world market share in 2004. In 2005, peak iPod first-generation Shuffle production occurred at a hundred thousand units per day, at the Asusfactory.
It lacks a display and the trademark scroll wheel, playlistmanagement features, and is missing the games, address book, calendar, alarm, and notes capability of larger iPods; it cannot be used with iSync. Due to the codec not being ported, it is incapable of playing Apple Lossless andAIFF audio files.
Due to superior audio technology in the SigmaTel STMP35xx SOC and SDK, the iPod Shuffle has a better bassresponse than a 4th generation iPod, according to a review published days after its release.[2][3]

iTunes offers some new features for iPod Shuffle. One is the ability to reduce the bit rate of songs to 128 kbit/s AAC. The conversion is done automatically, with the original fileleft untouched on the computer and the smaller (lower bit rate) file sent to the iPod Shuffle. Older versions of iTunes allowed an iPod Shuffle playlist to be viewed and changed while the unit is not connected; the next time the unit is connected, it can then be updated with the changed playlist. This functionality is no longer a part of iTunes as of iTunes 7.
The front of the iPod Shuffle has buttons for Play/Pause, Next Song/Fast Forward, Previous Song/Fast Reverse, and up and down volumeadjustment. On the reverse, it has a battery level indicator light (activated by a button) and a three-position switch to turn the unit off or set it to play music in order orshuffled. It plugs directly into a computer's USB port (either 1.1 or 2.0), through which it also recharges its battery, which has an expected life of around 12 hours between charges. The USB plug is hidden beneath a cap. The unit also comes with a lanyard that attaches to the iPod Shuffle via an attached cap and this allows the user to wear the iPod Shuffle around his or her neck.
The iPod Shuffle can also be used as a USB flash drive. iTunes allows a user to set how much of the drive will be allowed for storing files, and how much will be used for storing music.
Second generation[edit]A Second-generation iPod Shuffle in size-comparison to a Dellmouse.
On September 12, 2006, Apple announced the release of the second generation iPod Shuffle, calling it "the most wearable iPod ever".[4]First shipments of the unit were slated for an October 2006 arrival, but actually started shipping on Friday, November 3, 2006.[5]The second generation initially featured a lone 1 GB model in a silver brushed aluminum case similar to the second generation iPod Nano and the older iPod Mini. The new model is less than half the size of the first generation model at 41.2 x 27.3 x 10.5 mm (1.62 x 1.07 x 0.41 in), and is the size of the iPod Radio Remote available for iPod Nanos and 5th generation iPods. Apple claimed it was the "world's smallest MP3 player". This size includes the new built-in belt clip; the actual unit itself is thinner, with the entire device weighing only 15.5 g (0.55 ounces). The power/shuffle/no shuffle switch from the first generation version was separated into two controls to avoid an accidentally selected mode of operation. The formatting of the iPod itself is new to Apple, as the 2G (second generation) shuffle will only format itself to FAT32. iTunes issues a warning that the iPod is incorrectly formatted if brought to the Macintosh formatHFS+. All previous iPod models have allowed the usage of either the Mac format or the Windowsformat.[6]
On the second generation iPod Shuffle, USBconnectivity is provided via an included piece of hardware which acts as a docking station for the transfer of data and the recharging of the iPod's internal battery through its headphone jack. The second generation iPod Shuffle is also able to act as a flash drive, just like the first generation iPod Shuffle. However, unlike the first generation iPod Shuffle, the second generation does not have a built-in USB connector. This means that the docking station is required for connection to a computer on the second generation model.
The second generation Shuffle can play MP3, MP3 VBR, AAC, Protected AAC, Audible (formats 2, 3 and 4), WAV and AIFF. Due to its low processing power the only iTunes-supported file format that the iPod does not support is Apple Lossless.[citation needed] Using large file sizes inherent of WAVorAIFF files will very quickly fill the device's low 1 GB capacity. iPod Shuffle cannot play music from music video files.
On January 30, 2007, Apple announced the addition of four new colors to the iPod Shuffle line. Pink, orange, green, and blue choices have been made available via retailers and the Apple Store(online) in addition to the original silver color. The colors blue, green, and pink are essentially the same hues as the second generation iPod Nano and iPod Mini. The new orange color is a first for the iPod franchise. They also now come with the new redesigned headphones that were not included with the original silver model. The box was also changed to have gray text instead of the lime-green text; lime-green text indicating that the original headphones are included, gray text indicating that the new headphones are included On September 5, 2007, Apple refreshed the line with four new colors including a Product Redversion. The new colors are turquoise, lavender, mint green, and Product Red, with the previous colors orange, blue, green, and pink being discontinued.
On February 19, 2008, Apple introduced a 2 GB version of the iPod shuffle, retailing for US$69 and available in all the same colours as the 1 GB model. On the same day, the price of the 1 GB model was lowered from US$79 to US$49.
At the Apple Let's Rock Event on September 9, 2008, Apple released four new colors for the iPod Shuffle: blue, green, pink, and red, replacing the colors that were released in September 2007. The blue, green and pink variants of the iPod shuffle during this period reverted to shades that were similar to the colors that were released in January 2007, while the red variant was now a brighter shade.[7]
In June, 2009, Avon offered a gold iPod Shuffle (second generation) for $29 when purchased in conjunction with two ANEW skin care products.[8]
The second generation 2 GB iPod Shuffle was discontinued on March 11, 2009 and the 1 GB version was discontinued on September 9, 2009.
A third generation iPod Shuffle.
The third generation iPod Shuffle was released on March 11, 2009 and was said by Apple to be "jaw-droppingly small" and "The first music player that talks to you" as well as the first waterproof iPod.[9]with dimensions of 45.2×17.5×7.8 mm (1.78×0.69×0.31 in). It was available with a silver or black brushed aluminum case similar to the second generation iPod Shuffle. This made it the first iPod Shuffle that was available in black. It featuredVoiceOvertechnology that allowed song names, artist names, album names and playlist contents and names to be spoken in 20 different languages[10]using the Text-to-Speech incorporated in iTunes 8 and 9. It also gained support for multiple playlists, in contrast to previous versions of the iPod Shuffle, which allowed only a single playlist.
The inside of a third generation iPod Shuffle.
The third generation iPod Shuffle features a polished steel attachment clip, adopting for the first time the polished steel finishing previously found only on the larger iPods, rather than the brushed aluminum used in the second-generation iPod Shuffle. It also no longer had volume or track controls on the device itself. Instead, the packaged iPod earbudsincluded a three-button device on the right earbud cord. This adds the functions of changing between playlists, hearing the song title and artist of the track playing, as well as play/pause, track changes and volume control.[11]It is not possible to change songs or volume with most third-party headphones, since they lack these controls. However, since the iPod Shuffle begins playing music automatically when it is turned on, third-party headphones may still be used in "autoplay" mode (with no volume or playback controls). Some third-party headphones and headphone adapters include full support for the third generation iPod Shuffle.[12]The official headphones contain a chip designed by Apple to control the device. DRM is not however present in the chip as there is no encryption used.[13]
On September 9, 2009, Apple introduced three new colors for the iPod Shuffle: pink, blue, and green. The Apple Store also offered a 4 GB model made of polished stainless steel.[14]
What are the high school classes you need for video game Development?
