• 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 bounce rate is the percentage of visitors who leave a web site after viewing a single page.

    This is widely regarded as a bad thing because it may mean that visitors did not find what they were looking for and "bounced" away to another site. They left almost immediately.

    However, this is a broken metric in many cases. For example if you were looking for opening times of a retailer in your city and you found that info right on the homepage of the retailer, you will technically leave the site after a single page view. However it does not mean you did not find what you were looking for.

    Furthermore you may have visited some competing sites in a row, "bouncing" from on e to the next, still finding the exact information (closing times) on each of them in a single page view each.

  • 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).

  • The subnet mask is used in conjunction with the network address to determine which part of the address is the network address and which part is the host address.

    A subnet mask may look like 255.255.255.0 which means the first 3 bytes are part of the network and the last byte is the address of the host on the subnet.

    Another way to write the same network mask as above is /24 which means the 24 first bits (8 bits * 3 bytes) are part of 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 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.

  • 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.

  • 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

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

  • A domain name looks like some-name.com, another-name.org or even yet_another.ca for example.

    Those names are registered centrally for each "Top Level Domain" (TLD) such as .com , .org or .de ( "ca" being teh country code for Canada for example ).

    Once a domain name is registered it can be used to locate servers on the internet by using the Domain Name System in order to route e-mail or access web sites.
