What are the disadvantages of unstructured programs?
Unstructured programs can be difficult to maintain and debug due to their lack of organization and clear structure, making it challenging to understand the flow of the code. They often lead to code duplication and increased chances of errors, as developers may implement similar functionalities in multiple places. Additionally, unstructured programs can hinder collaboration among developers, as the absence of a standardized format complicates teamwork and integration of different code segments. This can ultimately result in longer development times and reduced software quality.
There's no solid evidence that Link is truly in love with Midna or not. It's a huge debate among fans though, because of a fews in-game hints, but has yet to be confirmed. At the end of it all it's all truly based on opinion though.
Is online translators illegal?
No, they are not.
If you go to google and type in translator
http://translate.google.com/translate_t?hl=en&sl=es&tl=en#
go to that website.
I do not use it because i know full Spanish but, it is helpful for people that need help on it.
You can translate ANY language you want like Examples
"Spanish to English"
"Chinese to French"
"Hindi to Portuguese"
all you have to do is type it in like "Hi" and then there is a 'swap" button right next where you can choose the language and just like this "English to portuguese"
English- Hi!- Portuguese- Oi!
Hope that helped!

Does the computer's CPU carries out high speed calculations?
A CPU does not calculate anything. A CPU processes information 1s and 0s, on or off, binary code. What look likes calculations are really just a program response. When you open the calculator in any computer and you input 2*2, the person who programed that pice of software basicly sais when you insert 2*2 you should display 4. It does not go like when you insert 2*2 cacluate two times two. It is nothing like that.
When you click somewhere it is programed to react to the position you clicked it does not perform a caculation to figure out what you want.
What do a command followed by Ellipsis mean?
It means that the command requires additional input in order to complete the command. Typically, a command that uses an ellipsis means that a dialog box will be displayed. For example, in Notepad, you have a "New" and "Save" command-- they take no additional input to complete (not necessarily, anyways). However, "Open..." and "Save As..." means there is a dialog that must be completed to complete the action (in this case, choosing the file to open or the file to save to).
What is the most common type of numeral system used today?
1. Decimal system
2. Binar system in informatics
Explain the principle of DVST system?
Conceptually the Direct View Storage Tube(DVST) behaves like a CRT with highly persistent phosphor. Pictures drawn on will be seen for several minutes (40-50 minutes) before fading. It is similar to CRT as far as the electronic gun and phosphor coated mechanisms are concerned. But instead of the electron beam directly writing the pictures on the phosphor coated CRT screen, the writing is done with the help of fine-mesh wire grid. The grid made of very thin, high quality wire is located with a dielectric and is mounted just before the screen on the path of the electron beam from the gun. A pattern of positive charges is deposited on the grid and this pattern is transferred to the phosphor coated CRT by a continuous flood of electrons'. This flood of electrons' is produced by a "flood gun" (This is separate frame the electron gun that produces the main electron beam).
Just behind the storage mesh is a second grid called the collection. The function of the collector is to smooth out the flow of flood electrons. Since large number of electrons are produced at high velocity by the flood gun, the collector grid, which is also negatively charged reduces, the acceleration on these electrons and the resulting low velocity flood pass through the collector and get attracted by the positively charged portions of the storage mesh (Since the electrons are negatively charged), by are repelled by the other portions of the mesh which are negatively charged (Note that the pattern of positive charges residing on the storage mesh actually defines the picture to be phosphor-coated screen and display the picture. Since the collector has slowed down the electrons, they may not be able to produces sharpand bright images. To over come this problem, the screen itself is maintained at a high positive potential be means of a voltage applied to a thin aluminum coating between the tube face and the phosphor. The other popular display device is the plasma panel device, which is partly similar to the DVST in principle, but over comes some of the undesirable features of the DVST.
A buffer register is the simplest kind of register; all it does is store a digital information temporarily. It holds the contents of the memory which are to be transferred from memory to other components. By acting as a buffer, it allows the central processor and memory units to operate independently without being affected by minor differences in operation.

What is the origin of hacking?
The term was used pejoratively by mathematician John Nash. When he became a C.L.E Moore Instructor at Massachusetts Institute of Technology (MIT) in 1951, he brought this term with him.[1]
The term achieved widespread use in the 1960s and its meaning then evolved to a quick, elaborate and/or bodged solution students devised for a technical obstacle; it was used withhacker, meaning one who discovers and implements a hack. The Jargon File, a glossary of slang from technical cultures at the MIT AI Lab, the Stanford AI Lab, Bolt, Beranek and Newman, Carnegie Mellon University, Worcester Polytechnic Institute, and others gave the tongue-in-cheek derivation "German word meaning 'someone who makes furniture with an axe'". This derivation was carried through when the Jargon File was eventually published as "The Hacker's Dictionary" in 1983 and later republished as "The New Hacker's Dictionary". However any student of German will know that the German word 'Hacker' (literal translation: "someone who chops") has nothing to do with making furniture, and that the derivation was intended as a wise-crack.
Over time, the meaning of the word there was expanded, perhaps through contact with the amateur radio community. It came to mean either a kludge, or the opposite of a kludge, as in a clever or elegant solution to a difficult problem. In the term "hack value" it also acquired a meaning of anything that was simultaneously fun and clever.
The initial hacker community at MIT, particularly those associated with the Tech Model Railroad Club, applied this pre-existing local slang to computer programming, producing the variant which first came into common use outside MIT.
The term "hack" was first used by US university computing centre staff in the mid-1960s. The context determined whether the complimentary or derogatory meanings were implied. Phrases such as "ugly hack" or "quick hack" generally referred to the latter meaning; phrases such as "cool hack" or "neat hack", to the former. In modern computer programming, a "hack" can refer to a solution or method which functions correctly but which is "ugly" in its concept, which works outside the accepted structures and norms of the environment, or which is not easily extendable or maintainable (see kludge). The programmer keeps beating on it until a solution is found. The jargon used by hackers is called "Hackish" (see the Jargon file). This should not be confused with "1337" or "leetspeak."
In a similar vein, a "hack" may refer to works outside of computer programming. For example, a math hack means a clever solution to a mathematical problem. The GNU General Public License has been described as[who?] a copyright hack because it cleverly uses the copyright laws for a purpose the lawmakers did not foresee. All of these uses now also seem to be spreading beyond MIT as well.
On many internet websites and in everyday language the word "hack" can be slang for "copy", "imitation" or "rip-off."
The term has since acquired an additional and now more common meaning, since approximately the 1980s; this more modern definition was initially associated with crackers. This growing use of the term "hack" is to refer to a program that (sometimes illegally) modifies another program, often a computer game, giving the user access to features otherwise inaccessible to them. As an example of this use, for Palm OSusers (until the 4th iteration of this operating system), a "hack" refers to an extension of the operating system which provides additional functionality. The general media also uses this term to describe the act of illegally breaking into a computer, but this meaning is disputed.
The term is additionally used by electronics hobbyists to refer to simple modifications to electronic hardware such as a graphing calculators,video game consoles, electronic musical keyboards or other device (see CueCat for a notorious example) to expose or add functionality to a device that was unintended for use by end users by the company who created it. A number of techno musicians have modified 1980s-era Casio SK-1 sampling keyboards to create unusual sounds by doing circuit bending: connecting wires to different leads of the integrated circuit chips. The results of these DIY experiments range from opening up previously inaccessible features that were part of the chip design to producing the strange, dis-harmonic digital tones that became part of the techno music style. Companies take different attitudes towards such practices, ranging from open acceptance (such as Texas Instruments for its graphing calculators and Lego for its Lego Mindstorms robotics gear) to outright hostility (such as Microsoft's attempts to lock out Xbox hackers or the DRM routines on Blu-ray Disc players designed to sabotage compromised players).
Where would your dad hide your laptop if your grounded and you've found it and he found out bout it?
It depends how smart he is, and how smart he thinks you are.
Personally if you'd found something I'd hidden once, I'd hide it in another building.

What do you do when you have an assignment do on the computer and your computer crashes?
If you have an assignmeant due, on the computer but your computer is down. I recommend writing it on paper. Or ask a friend to help you. GO to a friend's house. Or get an F. I hardly reccomend that though. Now I have a question, How did you summit this if your computer is appartently down.

Why is mainframe computing important?
Mainframes are primarily used to store and retrieve vast amounts of data simultaneously amongst many workstations. They are typically used in the financial and banking industries, the airline industry, space agencies and universities. That is, any small to large-scale organisation that requires a data centre.
Mainframes are often thought of as being enormous computers, however the size is actually immaterial. The smallest mainframe consists of just a single cabinet housing the processors, memory, hard-drives and backup facilities, not much unlike a standard desktop computer (albeit slightly bigger). The real difference is in the number of workstations. Whereas a desktop computer independently serves just one workstation with its own discrete set of programs and data, a mainframe can simultaneously serve hundreds if not thousands of workstations with the same programs and data.
Their size is primarily dependant upon the number of workstations and the amount of data that must be served. The mainframe itself (the processor and working memory) may be housed in one or more cabinets, while the data and backup facilities are spread over several more cabinets, perhaps even in separate rooms. The processor itself may consist of several processors all working in parallel (not unlike a multi-core processor, but actually made up of several multi-core processors).
Large mainframes are often confused with supercomputers. However supercomputers are specifically designed to perform high-speed, highly-complex floating point mathematics (with many decimal places), such as predicting the weather or to simulate nuclear reactions, whereas mainframes are specifically designed for transaction processing -- moving data around and performing simple arithmetic upon the data (with relatively few decimal places).
Although their role in the workplace has been partially replaced with cloud-based computing (server farms), the need to keep sensitive data in-house rather than entrusted to an external agency means they still have a vital role in the workplace, most notably in the banking industry.
Moreover, the "gameframe" is a newer breed of mainframe that includes features not unlike that of a supercomputer. They are best described as being a hybrid of the two. As the name suggests, they are aimed at the online gaming community, however their usage could be extended to the film and video effects industries.
