## Glossary
- [PDAF](https://www.adwaitx.com/glossary/pdaf-phase-detection-autofocus/): Phase Detection Autofocus (PDAF) is a sophisticated autofocus system commonly found in DSLR and mirrorless cameras. It works by analyzing the phase difference of light coming from different parts of the lens, allowing the camera to quickly and accurately determine the correct focus distance.
- [OIS](https://www.adwaitx.com/glossary/ois-optical-image-stabilization/): Definition: Hardware stabilization that moves the lens or sensor to counter small shakes. OIS helps reduce blur in low light photos and steadies video. It works alongside electronic stabilization, which crops and smooths motion in software.
- [LPDDR5](https://www.adwaitx.com/glossary/lpddr5-ram/): Definition: Low-power double data rate memory used in phones. LPDDR5 offers high bandwidth and lower power draw than older LPDDR generations, which helps with multitasking, gaming, and camera processing. Actual speed depends on the SoC memory controller and configuration.
- [IP68](https://www.adwaitx.com/glossary/ip68-rating/): The IP68 rating is an international standard that classifies the degree of protection provided by electrical enclosures against the intrusion of solid objects and liquids. It's commonly seen in specifications for smartphones, smartwatches, and other electronic devices.
- [Exynos 2200](https://www.adwaitx.com/glossary/exynos-2200/): The Samsung Exynos 2200 is a high-end system-on-a-chip (SoC) designed by Samsung Electronics, primarily for its flagship Galaxy smartphones. It was officially unveiled in January 2022.
- [Dynamic AMOLED 2X](https://www.adwaitx.com/glossary/dynamic-amoled-2x/): Dynamic AMOLED 2X is a display technology developed by Samsung, primarily found in their flagship smartphones and tablets. It's an evolution of their Super AMOLED and Dynamic AMOLED screens, focusing on enhancing several key areas for a superior visual experience.
- [Corning Gorilla Glass](https://www.adwaitx.com/glossary/corning-gorilla-glass/): Corning Gorilla Glass is a brand of chemically strengthened glass developed and manufactured by Corning Inc. It's designed to be thin, light, and durable, making it ideal for the screens of mobile devices like smartphones, tablets, and laptops, as well as wearables and other electronic displays.
- [Android 15](https://www.adwaitx.com/glossary/android-15/): Android 15 is Google’s 2024 Android release that focuses on privacy, safer app behavior, better media and camera controls, and smarter tools for big screens and foldables. It shipped first to Pixel phones, then to other brands through their own skins and schedules. It’s still current on many devices in 2025.
- [Bluetooth 5.3](https://www.adwaitx.com/glossary/bluetooth-5-3/): Bluetooth 5.3 is the latest version of the Bluetooth wireless communication standard, offering several enhancements over its predecessors. Here's a breakdown to help you understand it better:
- [4K](https://www.adwaitx.com/glossary/4k-video-recording/): Definition: Video captured at roughly 3840×2160 pixels. 4K packs four times the pixels of 1080p, so footage looks sharper on large TVs and monitors. Bitrate, frame rate, stabilization, and codec (H.264 or HEVC) affect quality and file size. Many phones record 4K at 30 fps on the selfie camera and up to 60 fps on the rear camera, depending on the chip and heat limits.
- [25 W](https://www.adwaitx.com/glossary/25w-super-fast-charging/): Definition: Samsung’s name for 25-watt wired charging that follows USB Power Delivery PPS. The charger and phone negotiate voltage and current in small steps to keep things efficient and cooler. Real charge time varies by battery level and heat. Using a certified 25 W PD PPS adapter typically gives the best results.
- [15 W Wireless](https://www.adwaitx.com/glossary/15-w-wireless-charging/): Definition: Wireless power transfer up to 15 watts using standards like Qi. The phone rests on a charging pad or stand; power moves through coils using electromagnetic induction. Charging speed depends on pad quality, alignment, temperature, and the phone’s thermal limits. Wireless is usually slower and less efficient than a good wired charger, but it is convenient on desks and nightstands.
- [120 Hz](https://www.adwaitx.com/glossary/120-hz-refresh-rate/): Definition: A display that refreshes 120 times per second. Higher refresh rates make motion look smoother and reduce blur when you scroll, play games, or switch apps. The trade-off is slightly higher power use, though adaptive modes may drop to lower rates to save battery. Most 120 Hz panels also support touch sampling above 120 Hz, which can improve responsiveness in games and drawing apps.
- [HTTP](https://www.adwaitx.com/glossary/http/): Definition: Hypertext Transfer Protocol is the application layer protocol most web APIs use to exchange requests and responses. It defines methods like GET, POST, PUT, and DELETE, status codes, headers, and message bodies. Modern APIs typically run over HTTPS, which wraps HTTP in Transport Layer Security to encrypt traffic and verify server identity. HTTP/2 introduces multiplexed streams over one connection, improving latency, while HTTP/3 builds on QUIC. Intermediaries such as proxies, gateways, and CDNs can observe or modify headers and caching behavior. Understanding method semantics and idempotency helps design predictable APIs and safe retries. Content negotiation selects formats via headers wisely.
- [API](https://www.adwaitx.com/glossary/api/): Definition: An API (Application Programming Interface) is a defined way for software components to communicate using requests and responses. It specifies available operations, input formats, output formats, and error handling, so different programs can work together reliably. APIs may be local, between processes on one machine, or remote over a network using protocols like HTTP. Public APIs expose services to external developers, while private or internal APIs support a company’s own systems. Styles include REST, GraphQL, and gRPC. Good APIs document endpoints, authentication, rate limits, and versioning, and often publish schemas such as OpenAPI for tooling and testing support. Monitoring tools track real usage.
- [Access token](https://www.adwaitx.com/glossary/access-token/): Definition: An access token is a short-lived credential a client sends to an API to prove permission to call protected endpoints. Servers validate the token before processing. Tokens usually carry scopes, expiry time, and issuer details, as either opaque strings or JSON Web Tokens. They must be stored securely and transmitted only over HTTPS. Most clients include tokens in the HTTP Authorization header using the Bearer scheme. When a token expires, the request fails with an authorization error. A companion refresh token can obtain a new access token without reauthenticating the user. Access tokens should be scoped narrowly to reduce risk.
- [Sparse attention](https://www.adwaitx.com/glossary/sparse-attention/): • A way for AI models to look at only the most useful parts of text instead of everything at once.• It skips less relevant tokens to save time and memory.
- [eSIM](https://www.adwaitx.com/glossary/esim/): • eSIM (embedded SIM) is a tiny chip built into your phone that stores your mobile plan digitally.• It lets you activate or switch carriers without a physical SIM card.
