  2. USB 3.0 - Wikipedia

    en.wikipedia.org/wiki/USB_3.0

    The specification defines a physically separate channel to carry USB 3.0 traffic. The changes in this specification make improvements in the following areas: Transfer speed – USB 3.0 adds a new transfer type called SuperSpeed or SS, 5 Gbit/s (electrically, it is more similar to PCI Express 2.0 and SATA than USB 2.0) [ 9 ]

    Cross section diagram of standard strut channel. Basic strut channel comes in the open box section 1 + 5 ⁄ 8 in (41 mm) square. A half height 1 + 5 ⁄ 8 in × 13 ⁄ 16 in (41 mm × 21 mm) version is also available, used mostly where mounted directly to a wall as it has significantly less stiffness and ability to carry loads across an open space or brace.

  4. Stainless steel - Wikipedia

    en.wikipedia.org/wiki/Stainless_steel

    Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an alloy of iron that is resistant to rusting and corrosion. It contains iron with chromium and other elements such as molybdenum, carbon, nickel and nitrogen depending on its specific use and cost. Stainless steel's resistance to corrosion results ...

  5. SAE 904L stainless steel - Wikipedia

    en.wikipedia.org/wiki/SAE_904L_stainless_steel

    SAE 904L stainless steel. 904L is an austenitic stainless steel. It is softer than 316L, [1] [2] and its molybdenum addition gives it superior resistance to localized attack (pitting and crevice corrosion) by chlorides and greater resistance reducing acids; in particular, its copper addition gives it useful corrosion resistance to all ...

  6. Solid-state drive - Wikipedia

    en.wikipedia.org/wiki/Solid-state_drive

    A solid-state drive (SSD) is a type of solid-state storage device that uses integrated circuits to store data persistently. It is sometimes called semiconductor storage device, solid-state device, and solid-state disk. [1][2] SSDs rely on non-volatile memory, typically NAND flash, to store data in memory cells.

  7. HDMI - Wikipedia

    en.wikipedia.org/wiki/HDMI

    Previous HDMI versions use three data channels (each operating at up to 6.0 Gbit/s in HDMI 2.0, or up to 3.4 Gbit/s in HDMI 1.4), with an additional channel for the TMDS clock signal, which runs at a fraction of the data channel speed (one tenth the speed, or up to 340 MHz, for signaling rates up to 3.4 Gbit/s; one fortieth the speed, or up to ...

  8. Slow-scan television - Wikipedia

    en.wikipedia.org/wiki/Slow-scan_television

    Slow-scan television (SSTV) is a picture transmission method, used mainly by amateur radio operators, to transmit and receive static pictures via radio in monochrome or color. A literal term for SSTV is narrowband television. Analog broadcast television requires at least 6 MHz wide channels, because it transmits 25 or 30 picture frames per ...

    en.wikipedia.org/wiki/Structural_steel

    Structural steel. Structural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section. Structural steel shapes, sizes, chemical composition, mechanical properties such as strengths, storage practices ...
