QA

Quality Assurance.

QAM

Quadrature Amplitude Modulation, is a method of combining two amplitude-modulated signals into a single channel, thereby doubling the effective bandwidth. QAM is used with pulse amplitude modulation (PAM) in digital systems, especially in wireless applications.

QBE

Query By Example, is a feature included with various database applications that provides a user-friendly method of running database queries.

QCIF

Quarter Common Intermediate Format, is a video conferencing format.

Qi

Qi is a functional programming language that is well suited for mathematical evaluations and the programming of mathematical equations and functions. Qi offers the advantages of pattern matching, lambda calculus consistency, static type checking and optional lazy evaluation.

QIF

Quicken Interchange Format, is file format for financial data.

QISKIT

Qiskit is an open-source software development kit for working with quantum computers at the level of circuits, pulses, and algorithms.

QLC

Quadruple Level Cell is a form of MLC memory.

QLED

Quantum dot Light-Emitting Diode.

QoS

Quality of Service.

QoSS

Quality of Storage Service, is a service that is geared toward accommodating disk storage by optimizing a storage system.

QoTD

Quote of The Day.

QPS

Queries-per-second is a measure of how much traffic a particular query server is handling at a given time. On the Internet, the activity in the collection of servers that serve as the domain name system is sometimes measured in queries-per-second.

QR Code

Quick Response code, is the trademark for a type of matrix barcode (or two-dimensional barcode) first designed in 1994. A QR code consists of black squares arranged in a square grid on a white background, which can be read by an imaging device.

QS

Quad Super Extended Graphics Array, is a display resolution, measuring 2560 x 2048 pixels in size with a 5:4 aspect ratio.

Quad Band

Mobile device that supports voice and data communications conforming to one bearer technology, such as GSM, but on four different sets of frequencies.

Quad Core

Four Processors in one chip.

Quantum Computing

Quantum computing is computing using quantum-mechanical phenomena, such as superposition and entanglement. A quantum computer is a device that performs quantum computing. Such a computer is completely different from binary digital electronic computers.

Query

A request of information on a database resulting in the output that meet the query.

Queue

A queue is a list of jobs that are awaiting to be processed.

Quicktime

A multimedia technology developed by Apple.

QWERTY

Term is used to describe a standard keyboard.
