Opteron is a discontinued x86 server and workstation processor line from AMD, and is the first processor that supports the AMD64 instruction set architecture (known generically as x86-64). It was released on April 22, 2003, with the SledgeHammer core (K8) and was intended to compete in the server and workstation markets, particularly in the same segment as the Intel Xeon processor. Processors based on the AMD K10 microarchitecture (codenamed Barcelona) were announced on September 10, 2007, featuring a new quad-core configuration. The last released Opteron CPUs are the Piledriver-based Opteron

ExpressCard, initially called NEWCARD, is an interface to connect peripheral devices to a computer, usually a laptop computer. The ExpressCard technical standard specifies the design of slots built into the computer and of expansion cards to insert in the slots. The cards contain electronic circuits and sometimes connectors for external devices. The ExpressCard standard replaces the PC Card (also known as PCMCIA) standards.

Nano-ITX is a computer motherboard form factor first proposed by VIA Technologies at CeBIT in March 2003, and implemented in late 2005. Nano-ITX boards measure , and are fully integrated, very low power consumption motherboards with many uses, but targeted at smart digital entertainment devices such as DVRs, set-top boxes, media centers, car PCs, and thin devices. Nano-ITX motherboards have slots for SO-DIMM.

ThinkCentre is a brand of business-oriented desktop computers and all-in-one computers, the early models of which were designed, developed and marketed by International Business Machines (IBM) since 2003. In 2005, IBM sold its PC business, including the ThinkCentre brand, to Lenovo. ThinkCentre computers typically include mid-range to high-end processors, options for discrete graphics cards, and multi-monitor support.

Pixlet is a video codec created by Apple and based on wavelets, designed to enable viewing of full-resolution, HD movies in real time at low DV data rates. According to Apple's claims, it allows for a 20–25:1 compression ratio. Similar to DV, it does not use interframe compression, making it suitable for previewing in production and special effects studios. It is designed to be an editing codec; however, low bitrates make it poorly suited to broadcast use.

FFV1 (short for FF Video 1) is a lossless intra-frame video coding format. FFV1 is particularly popular for its performance regarding speed and size, compared to other lossless preservation codecs, such as Motion JPEG 2000.
