  • interface computing

    in computing, an interface is a shared boundary across which two or more separate components of a computer system exchange information. the exchange can be between software, computer hardware, peripheral devices, humans, and combinations of these. some computer hardware devices, such as a touchscreen, can both send and receive data through the interface, while others such as a mouse or .

  • utility software

    utility software is software designed to help to analyze, configure, optimize or maintain a computer. it is used to support the computer infrastructure - in contrast to application software, which is aimed at directly performing tasks that benefit ordinary users. however, utilities often form part of the application systems.

  • optical fiber

    an optical fiber is a flexible, transparent fiber made by ding glass or plastic to a diameter slightly thicker than that of a human hair. optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths data rates than electrical .

  • fabry–pérot interferometer

    in optics, a fabry–pérot interferometer fpi or etalon is an optical cavity made from two parallel reflecting surfaces i.e.: thin mirrors . optical waves can pass through the optical cavity only when they are in resonance with it. it is named after charles fabry and alfred perot, who developed the instrument in 1899. etalon is from the french étalon, meaning 'measuring gauge' or 'standard'.

  • digital single-lens reflex camera

    a digital single-lens reflex camera digital slr or dslr is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor.. the reflex design scheme is the primary difference between a dslr and other digital cameras. in the reflex design, light travels through the lens and then to a mirror that alternates to send the image to either .

  • microphone

    the first microphone that enabled proper voice telephony was the loose-contact carbon microphone.this was independently developed by david edward hughes in england and emile berliner and thomas edison in the us. although edison was awarded the first patent after a long legal dispute in mid-1877, hughes had demonstrated his working device in front of many witnesses some years earlier, and .

    this image is currently used as a second image in the lion taxobox, and i'm not convinced that it is useful to have two images in a taxobox. it is also used in the park stub, which has three excellent pictures and they should all be kept in the article but almost no text. the technical issue i'm most concerned about is the appearance of the lower, unfocused branches of the tree. what caused .

  • asbestos

    asbestos pronounced: / æ s ˈ b ɛ s t ə s / or / æ s ˈ b ɛ s t ɒ s / is a term used to refer to six naturally occurring silicate minerals.all are composed of long and thin fibrous crystals, each fiber being composed of many microscopic 'fibrils' that can be released into the atmosphere by abrasion and other processes. asbestos is an excellent electrical insulator and is highly heat .

  • curtain wall architecture

    a curtain wall system is an outer covering of a building in which the outer walls are non-structural, utilized only to keep the weather out and the occupants in. since the curtain wall is non-structural, it can be made of lightweight materials, thereby reducing construction costs. when glass is used as the curtain wall, an advantage is that natural light can penetrate deeper within the building.

  • isopropyl alcohol

    isopropyl alcohol iupac name propan-2-ol; commonly called isopropanol or 2-propanol is a colorless, flammable chemical compound chemical formula ch 3 chohch 3 with a strong odor. as an isopropyl group linked to a hydroxyl group, it is the simplest example of a secondary alcohol , where the alcohol carbon atom is attached to two other carbon atoms.

  • emulsion

    emulsions, being liquids, do not exhibit a static internal structure. the droplets dispersed in the continuous phase sometimes referred to as the “dispersion medium” are usually assumed to be statistically distributed. the term 'emulsion' is also used to refer to the photo-sensitive side of photographic film.
