• Measurement of resolution that is used for scanning and printing. Generally, higher DPI results in a higher resolution, more visible detail in the image, and a larger file size.

  • 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 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.

  • 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.

  • 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

  • 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.
