  • 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.

  • 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
