• The Institution of Electrical and Electronics Engineers (IEEE) is an non-profit organisation involved in advance development of all technologies related to electricity.

  • Wi-Fi Protected Setup (WPS) is a standard for setting up a wireless home network.

    If your wireless access point/router supports WPS, you can configure the wireless network connections easily without requiring a computer. For example, all you may have to do is press a button on the devices to register them on the network.

  • 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 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.

  • The Bit depth describes the number of bits used to represent the color of a single pixel in a bitmapped image. Higher color depth gives a broader range of distinct colors. As the number of bits increases, the number of possible colors becomes impractically large for a color map.

    1-bit color is commonly called as monochrome or black & white.

  • 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
  • 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".

    Examples: "Buy now" button, "Sign up", "Download now", "Subscribe here"...

  • DNS is a system that stores information associated with domain names in a distributed database on networks such as the Internet.

    For example, when you type in a domain name like, for example, mozilla.org, you computer will automatically query the Domain Name System to find the actual IP address of the server you are trying to reach, for instance: 63.245.209.11.

    You can see that query in more detail by opening a command window and typing in:
    nslookup mozilla.org

  • 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.
