  • File format used to exchange data between disparate applications. The file format, originally
    introduced by Microsoft Excel, has become a de facto standard throughout the industry, even among non-Microsoft platforms.

  • 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).

  • 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

  • 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.

  • 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.

  • An Automatic Document Feeder (ADF) is a mechanism that will automatically feed an original sheet of paper so that a printer can scan some amount of the paper at once.

  • 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.
