• 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.

  • The Digital Living Network Alliance (DLNA) is a standard that allows devices on a home network to share information with each other.

    It is typically used to store media files (photos, music, videos...) on a central server and allow devices like connected TVs or music palyers to access these media files directly through the network.

  • 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
  • A suite of protocols developed by Apple for computer networking. It was included in the original Macintosh (1984) and is now deprecated by Apple in favor of TCP/IP networking.

  • CRO is the method of improving the performance of a website, not by directing more traffic to it, but instead by getting a higher proportion of the existing traffic to convert.

    The underlying assumption is that each website has a purpose and is trying to get its visitors to take some action. Therefore it should have a Call To Action (CTA). CRO uses different methods to get people to follow the CTA.

    Sometimes it means making the CTA more prominent, or more explicit. Sometimes, it means removing distractions or friction in the process.

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

  • An image type that simulates grayscale by varying the density of dots in a given area.

    Highly colored areas consist of a large density of dots, while lighter areas consist of a lower density of dots.

  • An Internet Service Provider is a company that lets you access the Internet from your home or office by using a DSL modem, a cable modem or any other device (including sattelite links, etc.).

    They are a gateway between the connection that goes into your home/office and the rest of the Internet.

  • 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.

  • 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.
