1. Federated Object Naming Service (F-ONS)
   Federated Naming Service (F-ONS) provides a method for hooking up or federating, multiple naming services under a single, simple uniform interface for the essential naming and directory operations.

   The service supports resolution of composite names―names that span multiple naming systems―through the naming interface. Each member of a federation has autonomy in its choice of naming conventions, administrative interfaces, and its particular set of operations, other than name resolution.
2. Field of View (FoV)
   Field of View (FoV) represents the visual area in which users can see virtual content in an augmented reality headset. This term can also be explained as a measurement of the angle formed by the distance from the user to a fixed point in space and the bounds of vision.

   FOV allows for coverage of an area rather than a single focused point. In virtual reality (VR), a large FOV is essential to getting an immersive, life-like experience. Wider FOV also provides better sensor coverage or accessibility for many other optical devices.
3. File Transfer Protocol (FTP)
   The File Transfer Protocol (FTP) is a standard network protocol used to transfer computer files from one host to another host over a TCP-based network, such as the Internet.

   A standard network protocol used to transfer computer files from one host to another host over a TCP-based network, such as the Internet.
4. Firmware
   Firmware is a software program or set of instructions programmed on a hardware device. The firmware provides the necessary instructions for how the device communicates with the other computer hardware.

   Firmware provides the necessary instructions for how the device communicates with the other computer hardware. It can be thought of as "semi-permanent" since it remains the same unless it is updated by a firmware updater. The user may need to update the firmware of certain devices, such as hard drives and video cards in order for them to work with a new operating system.
5. Firmware Over-the-Air (FOTA)
   Firmware Over-the-Air (FOTA) is a process of updating a mobile phone’s operating system and software over the network, rather than having the consumer come into a service center for updates.

   FOTA-capable phones download upgrades directly from the service provider. Traditionally, the consumer was responsible for updating mobile device firmware via a device-specific service facility or PC download. These inconvenient methods often resulted in inconsistent firmware upgrades and other issues. FOTA allows manufacturers to provide efficient and timely firmware updates for handsets, which increases customer satisfaction and reduces technical support requirements.
6. Firmware Update Management Object (FUMO)
   An open mobile alliance specification for updating the firmware of mobile devices over the air. FUMO allows mobile operators to update mobile devices across network infrastructure without requiring consumers or network engineers to initiate upgrades through direct contact

   FUMO allows mobile operators to update mobile devices across network infrastructure without requiring consumers or network engineers to initiate upgrades through direct contact. FUMO allows mobile devices to be updated over-the-air using the industry-standard protocol OMA DM. It enables operators and device manufacturers to perform updates over-the-air ranging from the simple ones (e.g.:security patch) to the most complex (e.g.: important parts of the operating system). OMA DM/FUMO is an industry standard which allows updates to be installed over-the-air using a device-independent and cross-platform protocol.
7. Fog Computing
   Fog computing is a term created by Cisco that refers to extending cloud computing to the edge of an enterprise's network. In a fog computing environment, much of the processing takes place in a data hub on a smart mobile device or the edge of the network in a smart router or other gateway devices.

   Cisco introduced its fog computing vision in January 2014 as a way of bringing cloud computing capabilities to the edge of the network and as a result, closer to the rapidly growing number of connected devices and applications that consume cloud services and generate increasingly massive amounts of data. The goal of fogging is to improve efficiency and reduce the amount of data that needs to be transported to the cloud for data processing, analysis and storage. This is often done for efficiency reasons, but it may also be carried out for security and compliance reasons. In a fog computing environment, much of the processing takes place in a data hub on a smart mobile device or on the edge of the network in a smart router or other gateway device. This distributed approach is growing in popularity because of the Internet of Things (IoT) and the immense amount of data that sensors generate.
8. Frequency Band
   In telecommunication, a frequency band is a specific range of frequencies in the radio frequency (RF) spectrum, which is divided among ranges from very low frequencies (vlf) to extremely high frequencies (ehf). Each band has a defined upper and lower frequency limit.

   In telecommunication, a band - sometimes called a frequency band - is a specific range of frequencies in the radio frequency (RF) spectrum, which is divided among ranges from very low frequencies (vlf) to extremely high frequencies (ehf). Each band has a defined upper and lower frequency limit. For example, the 2.4 MHz band is used for Wi-Fi and Bluetooth communication.
