File Transfer Protocol (FTP)

  08/26/08 07:19, by admin, Categories: Networks

FTP is a protocol for transferring files over TCP/IP networks such as the Internet.

To transfer files, you need to connect to an FTP server with some FTP client software.

FTP can be used to transfer very large files, especially files that are too large to be sent via email. However, the need for a server to exchange files with someone else makes this less practical than email.

FTP is also commonly used to upload web pages and web applications to web sites. Most web servers also feature an FTP server.

Some commonly use FTP clients are:

  • Windows: FileZilla
  • Mac: CyberDuck, Transmit
  • Unix: ftp command

Fuser Unit

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.

Term used for a toner usage measurement on laser printing. For example, 5% coverage means that an A4 sided paper has about 5% image or text on it. So, if the paper or original has complicated images or lots of text on it, the coverage will be higher and at the same time, a
toner usage will be as much as the coverage.

eXtensible Markup Language (XML)

  08/24/08 10:57, by admin, Categories: Uncategorized

XML stands for eXtensible Markup Language.

It is a way of organizing text and/or contents with tags. Tags look like this:

<sometag>some content</sometag>

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 />.

Other XML dialects include RSS and Atom.
