Markdown is a lightweight markup language for creating formatted text using a plain-text editor. John Gruber created Markdown in 2004 as an easy-to-read markup language. Markdown is widely used for blogging, instant messaging, and large language models, and also used elsewhere in online forums, collaborative software, documentation pages, and readme files.

Zigbee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios, such as for home automation, medical device data collection, and other low-power, low-bandwidth needs, designed for small-scale projects which need wireless connection. Hence, Zigbee is a standard for low-power, low-data-rate, close-proximity (i.e., personal area) wireless ad hoc networks.

Sempron has been the marketing name used by AMD for several different budget desktop CPUs, using several different technologies and CPU socket formats. The Sempron replaced the AMD Duron processor and competed against Intel's Celeron series of processors. AMD coined the name from the Latin semper, which means "always", to suggest the Sempron is suitable for "daily use, practical, and part of everyday life". The last Semprons were launched in April 2014. The brand was retired with the launch of the AMD A-Series APUs.

AirPlay is a proprietary wireless communication protocol stack/suite developed by Apple Inc. that allows the streaming of multimedia and device screens, together with related metadata, between compatible devices. Originally implemented only in Apple's own software and hardware, the company has since licensed the AirPlay protocol stack to third-party manufacturers and it has been implemented on devices such as television sets and home audio systems. AirPlay works through either a direct peer-to-peer connection between devices or through an infrastructure local network.

Animated Portable Network Graphics (APNG) is a file format which extends the Portable Network Graphics (PNG) specification to permit animated images that work similarly to animated GIF files, while supporting images with a higher color depth and full alpha transparency not available for GIFs. It also retains backward compatibility with non-animated PNG files. It was developed by the Mozilla Foundation in 2004.

The NSLU2 (Network Storage Link for USB 2.0 Disk Drives) is a network-attached storage (NAS) device made by Linksys introduced in 2004 and discontinued in 2008. It makes USB flash memory and hard disks accessible over a network using the SMB protocol (also known as Windows file sharing or CIFS). It was superseded mainly by the NAS200 (enclosure type storage link) and in another sense by the WRT600N and WRT300N/350N which both combine a Wi-Fi router with a storage link.

DVR-MS (Microsoft Digital Video Recording) is a proprietary video and audio file container format, developed by Microsoft used for storing TV content recorded by Windows XP Media Center Edition, Windows Vista and Windows 7.
