Acronyms

Postby Layzie Bone » Sun Dec 09, 2007 2:20 am

We all know what RAM is Random Access Memory, but some people, not everyone doesn't know what it does, and that's what this is going to cover.


PSU - Power Supply Unit - This is your computer's power supply, this is where your plugging the power cord into your computer. The PSU converts AC electric (Alternating Current later on in this thread) to DC, there are three main output voltages: 12 V, 5 V, and 3.3 V. If the PSU does not operate correctly it can damage other componets in your computer such as the motherboard and processor, in some cases it can kill the hard disk depending on what has malfunctioned in the PSU, generally what I see is the 5 V part of the PSU is usually what goes bad.

AC & DC - Alternating Current (AC) - Direct Current (DC) - Alternating Current can be found in your home usually varies between 110 V to 130 V, though the standard is 120 V. The key term here is alternating, the direction of the electricity changes about 50-60 times a second (also reffered to 50/60 Hz (Hertz) or cycles, because of this alternating directions allows electricity to travel further distances. When Thomas Edison first lit up New York City he was using Direct Current, because of his method many generators were used, a few years later Westinghouse (not the cheap TV's) developed Alternating Current. Direct current only flows in one direction. FYI - in AC electric there is no true polarity, some may argue, but there really can't be.

Volts - Dealing with electricity, look at voltage like a crave, the higher the voltage the more electricity wants to flow, thus when lightning strikes a very high voltage is needed to travel through air as it air is a good insulator.

Amperes - Also known as amps. This is the actual rate in which electricity flows.

Impedence / Resistance / Ohms - All are the same thing, Ohms is the measurement used, this is the restriction of the flow of electricity, higher resistances will require higher voltages to maintian a steady flow (amps) of electricity.

CPU - Central Processing Unit - This is where all the number crunching takes place, everything you see and everthing you do on a computer goes through this componet first. Other terms like GPU Graphics Processing Unit are other Processors that are in your computer.

DDR (DDR2 DDR3 GDDR2 GDDR3) - That just means Double Data rate. This terms deals with computer memory. Used to you had SD Memory which may have ran at 133 MHz, well with DDR memory you could still have 133 MHz but would be equivalant to 266 MHz, getting twice the performance. Currently in most computers DDR2 Memory is used, which is about 2x times faster than DDR and speeds of 533, 667, 800 and 1066, when DDR2 first came out 400 Mhz was also available. The higher the speed the better the performace.

Hz - Hertz (kHz, MHz, GHz) - Hertz - 1 Hz is one cycle per second, whether that be sound or sothing going in some sort a loop. Since this can expressed as sound or the speed of your computer here's a few thing that might help your grasp the idea. Your ears can hear frequences from around 20 Hz (deep bass) to 20 kHz like a dog whinning, the "k" in kHz means kilo meaning thousands, so when your dog whines the sound waves hit your ears 20 thousand times per second. Computers on the other hand operate in MHz and GHz, M for millions and G for billions.

That's all for now, more later...give me suggestions?

I thought we could add these to your list Wanabe...

http: - HyperText Transfer Protocol
https: - HyperText Transfer Protocol - over Secure Socket Layer (SSL)
SSL - Secure Socket Layer - when the "s" follows the http,
look for the padlock icon in the URL and lower RHS of your screen.

URL - Uniform Resource Locator - when you type the address of a web page into your browser,
you are typing a URL - eg http://forums.cricketmx.com

RHS - just kidding :wink:

HTTP - Hyper Text Transfer Protocol - Protocols are a standards of transmitting data, HTTP is a standard for transmitting web pages and the media required to show them. There are many different protocols, such as TCPIP, which is necessary for your computer to see other computers on the internet.

HTML - HyperText Markup Language - A webbased language for webpages, not all webpages use HTML, some use other platforms, such as ASP, Java, and others.

Here's an example of some basic HTML coding, or also known as tags, similar of what this board allows you to do:

Code: Select all
<HTML>
<head>
<title>Here's my webpage!</title>
</head>
<body>
<h1>
<center>
This is my webpage
</center>
<p>
</h1>
<h3>
This is just a sample of some basic HTML Coding<br>If you paste this in Notepad and save it as a HTM or HTML file<b>you will be able to see the output of this code.<p>
This is what is used to make a hyperlink:<br>
<a href="http://www.cricketmx.com">Click Here!</a><br>
This is what is used to put a picture in a webpage:<br>
<img src="http://forums.cricketmx.com/templates/EternalDarkness/images/logo_phpBB.gif"><br>
Not sure if that's right, but who the hell uses notepad for making pages this day & age?</h3>
</body>
</html>


HTTPS / SSL - Secure Socket Layer - SSL is encyrption, this means there is a fat chance in hell anyone is going to know what you're viewing, or buying in most cases. You might see 128-bit SSL, or even 256-bit SSL, the higher the encrytion, the better, because this makes it harder to put the data back togeather again.

I'll do SATA/ RAID next time....

AJAX - Coming Clean On Acronyms

Defining Ajax
February 18, 2005


Ajax isn’t a technology. It’s really several technologies, each flourishing in its own right, coming together in powerful new ways. Ajax incorporates:

* standards-based presentation using XHTML and CSS;
* dynamic display and interaction using the Document Object Model;
* data interchange and manipulation using XML and XSLT;
* asynchronous data retrieval using XMLHttpRequest;
* and JavaScript binding everything together.

The classic web application model works like this: Most user actions in the interface trigger an HTTP request back to a web server. The server does some processing — retrieving data, crunching numbers, talking to various legacy systems — and then returns an HTML page to the client. It’s a model adapted from the Web’s original use as a hypertext medium, but as fans of The Elements of User Experience know, what makes the Web good for hypertext doesn’t necessarily make it good for software applications.

Ajax Is Not an Acronym
Fri, 27 Apr 2007


And it never was.

In the original article about Ajax, the author states: (See the article above: Defining Ajax
February 18, 2005)


The name is shorthand for Asynchronous JavaScript + XML, and it represents a fundamental shift in what's possible on the Web.

Although he never calls it an acronym and never uses it as such, this particular statement can be blamed for the widespread misconception that Ajax is an acronym. Microsoft even thinks it's written as AJAX. Thankfully, most books get it right.

The assertion that it's AJAX reminds me of similar assertions that Perl is PERL. If you have some extra time, read this debate from a few years ago; it's entertaining.

In my talk Tuesday night at New York PHP, I tried to provide a concise and precise definition of Ajax as I interpret it:

Client-side technologies / techniques that allow two-way communication between the client and the server.

I want to include all of the creative client-side techniques used to communicate with the server (e.g., IFrames) without including the purely client-side techniques that don't interact with the server and therefore aren't Ajax at all.

I think my simplistic definition might still be too restrictive, though. In the case of something like Netflix's star rating, the goal is just to send thhttp://shiflett.org/blog/2007/apr/aja ... n-acronyme rating to the server. You can update the interface with CSS, so two-way communication isn't necessary. You could argue that the use of <script src=""> doesn't really constitute two-way communication either. I'm sure there are other examples.

How do you define Ajax?

Now...
The assertion that it's AJAX reminds me of similar assertions that Perl is PERL

Knits my brow (with great difficulty mind u :wink: ) and considers PERL...
