Augmented Reality (AR) is a technology that overlays digital information—such as images, text, or 3D models—on the real world. Unlike VR, AR does not replace reality; it enhances it. AR is often experienced via smartphones, tablets, or dedicated AR glasses.
Sample rate is how many times per second an analog audio signal is measured (sampled) to store it digitally. It is expressed in Hertz (Hz). CD quality is 44,100 Hz (44.1 kHz), meaning the sound is sampled 44,100 times per second. Higher sample rates can capture more detail.
A shader is a program that runs on the GPU and determines how pixels or vertices are computed and displayed. Shaders control effects like lighting, shadows, reflections, and materials. There are different types: vertex shaders (move points), fragment/pixel shaders (determine colors), and compute shaders.
Virtual Reality (VR) is a technology that creates a fully artificial, computer-generated environment in which users can navigate and interact. VR is experienced through headsets that cover the entire field of view, often combined with motion controllers for interaction.
