frequency band - In telecommunications, a frequency band -- sometimes called a band -- refers to a specific range of frequencies in the electromagnetic frequency spectrum assigned to certain applications.
frequency jammer - Frequency jamming is the disruption of radio signals through use of an over-powered signal in the same frequency range.
frequency-division multiplexing (FDM) - In frequency-division multiplexing (FDM), multiple signals are combined for transmission on a single communications line or channel, with each signal assigned to a different frequency (subchannel) within the main channel.
frequency-hopping spread spectrum (FHSS) - Frequency-hopping spread spectrum (FHSS) transmission is the repeated switching of the carrier frequency during radio transmission to reduce interference and avoid interception.
frequency-shift keying (FSK) - Frequency-shift keying (FSK) is a method of transmitting digital signals using discrete signals.
friendly name - A friendly name is a term used to refer to a device, application file, certificate or other IT asset instead of its technical name.
front end and back end - Front end and back end are terms used by programmers and computer professionals to describe the layers that make up hardware, a computer program or a website which are delineated based on how accessible they are to a user.
fronthaul - Fronthaul, also known as mobile fronthaul, is a term that refers to the fiber-based connection of the cloud radio access network (C-RAN), a new type of cellular network architecture of centralized baseband units (BBUs) and remote radio heads (RRHs) at the access layer of the network.
FTC (Federal Trade Commission) - The FTC, or Federal Trade Commission, is a United States federal regulatory agency designed to monitor and prevent anticompetitive, deceptive or unfair business practices.
FUBAR - FUBAR is an acronym that originated in the military to stand for the words "f***ed up beyond all repair.
fuel cell - A fuel cell is an electrochemical cell that derives its energy from combustible substances such as hydrogen, methane, propane, methanol, diesel fuel or even gasoline.

full backup - A full backup is the process of making at least one additional copy of all data files that an organization wishes to protect in a single backup operation.
full-disk encryption (FDE) - Full-disk encryption (FDE) is a security method for protecting sensitive data at the hardware level by encrypting all data on a disk drive.
full-duplex - Full-duplex data transmission means that data can be transmitted in both directions on a signal carrier at the same time.
full-stack developer - A full-stack developer is a type of programmer that has a functional knowledge of all techniques, languages and systems engineering concepts required in software development.
fully qualified domain name (FQDN) - A fully qualified domain name (FQDN) is the complete address of an internet host or computer.
function as a service (FaaS) - Function as a service (FaaS) is a cloud computing model that enables cloud customers to develop applications and deploy functionalities and only be charged when the functionality executes.
functional requirements - Functional requirements are the desired operations of a program, or system as defined in software development and systems engineering.
fuzz testing (fuzzing) - Fuzz testing (fuzzing) is a quality assurance technique used to discover coding errors or bugs and security loopholes in software, operating systems and networks.
fuzzy logic - Fuzzy logic is an approach to computing based on "degrees of truth" rather than the usual "true or false" (1 or 0) Boolean logic on which the modern computer is based.
fuzzy search - A fuzzy search is a technique that uses search algorithms to find strings that match patterns approximately.
NetApp FlexPod - NetApp FlexPod is a reference architecture for server, storage and networking components that are pretested and validated to work together as an integrated infrastructure stack.
What is a framework? - In general, a framework is a real or conceptual structure intended to serve as a support or guide for the building of something that expands the structure into something useful.
What is a functional specification document? - A functional specification is a formal document used to describe a product's intended capabilities, appearance and interactions with users in detail for software developers.
What is face detection and how does it work? - Face detection, also called facial detection, is a computer technology that identifies human faces in digital images and video.
What is feature engineering? - Feature engineering is the process that takes raw data and transforms it into features that can be used to create a predictive model using machine learning or statistical modeling, such as deep learning.
What is fine-tuning in machine learning and AI? - Fine-tuning is the process of taking a pretrained machine learning model and further training it on a smaller, targeted data set.
