A modulator-demodulator is a device used to transmit digital data over an analog channel. It modulates/demodulates a carrier signal in order to encode digital information onto it.
A modem is typically used to transmit computer data over POTS phone lines.

The CTA is the primary usier interface element (button, link, form...) that asks the user to take the action the website would like its visitors to take. This results in a "Conversion".

An Automatic Document Feeder (ADF) is a mechanism that will automatically feed an original sheet of paper so that a printer can scan some amount of the paper at once.
XML stands for eXtensible Markup Language.
It is a way of organizing text and/or contents with tags. Tags look like this:
Of course, although possible, this is not designed to be read by humans. It is designed to be processed by machines. Typically one program generates an XML document and another one computes it to some further extent.
And XML document very much looks like an HTML document, except that the tags are different.
There are actually many different dialects of XML, each for a different purpose. Each of these dialects has its own tags. And even more tags can be added. Hence the "eXtensible" in the name.
There is an XML dialect for writing web pages. It is called XHTML. It is basically the same thing as HTML except for minor syntaxic differences. For example in HYML you would write <BR> whereas in XML you would write <br />.
HTML is the language used to create web pages such as the one you are currently looking at.
HTML is a standard normalized by the W3C.
The Joint Photographic Experts Group (JPEG) algorythm is a very commonly used method of compression for photographic images. It is also a file format used for storing or transmitting photos.
The JPEG algorythm is lossy which means some details of the original picture are lost when compressing the algorythm. The algorythm has a quality setting allowing to set a balance between smaller file size and better quality.
Duty cycle is the page quantity which does not affect printer performance for a month. Generally the printer has the lifespan limitation such as pages per year. The lifespan means the average capacity of print-outs, usually within the warranty period. For example, if the duty cycle is 48,000 pages per month assuming 20 working days, a printer limits to 2,400 pages a day.
The part of a laser printer that melts the toner onto the print media. It consists of a hot roller and a back-up roller. After toner is transferred onto the paper, the fuser unit applies heat and pressure to ensure that the toner stays on the paper permanently.
This is why paper is warm when it comes out of a laser printer.
WPA-PSK (WPA Pre-Shared Key) is special mode of WPA for small business or home users.
A shared key, or password, is configured in the wireless access point (WAP) and any wireless laptop or desktop devices. WPA-PSK generates a unique key for each session between a wireless client and the associated WAP for more advanced security.
