• IEEE 1284

    IEEE 1284 is a parallel port standard of conectivity interface developed by the Institution of Electrical and Electronics Engineers (IEEE).  The term "1284-B" is a connector end of a parallel cable which is attached to other components (i-e: a printer).

  • eXtensible Markup Language (XML)

    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.

  • Dual Inline Memory Module (DIMM)

    A small circuit board that holds memory.

  • Duty Cycle

    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.

  • Institute of Electrical and Electronics Engineers (IEEE)

    International non-profit, professional organization for the advancement of technology related to electricity.

  • File Transfer Protocol (FTP)

    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
  • Dynamic Host Configuration Protocol (DHCP)

    Network protocol used for automatic configuration of IP computers/devices. A DHCP server provides configuration parameters specific to the DHCP client host requesting, generally, information required by the client host to participate on an IP network. DHCP also provides a mechanism for allocation of IP addresses to client hosts.

  • Grayscale

    Shades of gray that represent light and dark portions of an image.

    When color images are converted to grayscale; colors are represented by various shades of gray depending on their brightness.

  • BMP

    A bitmapped image format used internally by the Microsoft Windows graphics subsystem (GDI), and used commonly as a simple graphics file format on Windows.

  • AppleTalk

    AppleTalk is a proprietary suite of network protocols developed by Apple. It was included in the original Macintosh (1984) but is now deprecated by Apple in favor of TCP/IP.
