AM Amplitude Modulation AM is the name given the to the technique of varying the amplitude or loudness of one signal known as the carrier typically an audio signal, swinging both above and below 0 volts with a second signal called the modulator. In the typical amplitude modulation AM scenario, a low frequency oscillator with a positive voltage say, between 0v and 5v, or maybe something smaller such as between 1v and 2v is fed into the control input of a voltage controlled amplifier to add vibrato to an audio signal passing through it.

Function Argument s The arguments of a function are just its input. Nonetheless, this general form is very convenient because you only have to write the formula once and then you can refer to it in a simpler and more general way. HyperText means text that includes links that, with appropriate support from a browser, allow you to "jump" from one part of a text to another part or to an entirely different page.
Markup means embedded symbols that function like printer's composition marks to control the appearance or rendering of a text. HTML allows formatted textual information to be transmitted in a linear fashion using at most different ASCII characters and shares characteristics with braille.
The keyboard layout that is typically printed on the keys of computer keyboard is Standard You can change the layout as a Setup option in most modern computer systems.
Some people use the Dvorak layout because they find it easier. Other layouts are appropriate for non-Latin alphabets. Most people stick with one layout and use different mappings for different purposes.
Most keyboards can sense several keys being pressed simultaneously so that, for example, a Shift key can be used to double the number of codes.
In this case, one keyboard event consists of several signals. However, if you are interested in simulated six-key typingyou've probably discovered that although most keyboards recognize up to three simultaneous keystrokes, only a few can recognize six keys being pressed simultaneously.
Keyboard Mapping Table A keyboard mapping table is an internal table that determines the relationship between a keyboard event and the ultimate results. It is easiest to envision this as a two-step process. The keyboard layout determines the numerical code associated with an event and then the mapping table determines the meaning of the numerical code.
If you don't like a mapping table that is built into the software you are using, you often don't have any way of directly changing the table.
For example, Braille ASCII uses code which is the standard ASCII code for the numeral 4 character for the braille cell with dotswhich represents the period punctuation mark in literary braille.
The ASCII code for the period keyboard character with the standard keyboard mapping used by most American keyboards is code A keyboard mapping that has been found convenient in the past for literary braille is to use the lower-case letters for the cells that correspond to the letters while reserving some of the upper case letters for the two-letter signs such as "C" for dots or "ch".
There are 47 keys for keyboard characters on most standard computer keyboards so, with the Shift key, there are 94 options for the 63 braille cells. If you don't have any trouble remembering the letters used for numerals in literary braille, you could also use the keyboard numerals as NUMBRL codes for the indicators with dots only in the right-hand column of a cell.
LaTEX LaTEX is a widely-used extension to the TEX formatting system that adds some new features including a more logical recognition of document structure with items such as chapters and sections.
Many scientists prefer to type formulas directly in LaTEX without special software. However, there are also numerous easy to use but less efficient graphical interfaces like MathType and ScientificNotebook available for this purpose.The education field is so full of acronyms and specialized words that it can seem like a confusing alphabet soup!

As always in academic writing, the goal of maximizing clarity should be kept in view when abbreviations are considered.
Saving space is not a sufficient reason to abbreviate; the abbreviation must also help the reader to comprehend your point.
