An adapter is a hardware device or software component that converts transmitted data from one presentation form to another. The data presentation can be, for example, a message sent between objects in an application or a packet sent through a network. A null modem adapter enables users to transform a normal serial cable into a null modem. It contains the necessary crosslinks between the signals. A null modem adapter converts any straight-through wired cable with connectors into a null modem "cross-wired" configuration. This configuration is suitable for many serial PC Read More

A proximity sensor is an electronic device that is designed to detect the presence of objects, people, or other living things within a given distance and detection threshold. Proximity sensors are able to detect objects without physically touching them by transmitting a detecting field/beam such as infrared, acoustic, and inductive transmissions. When the sensor receives the transmission, it analyzes the return signal for interruptions that indicate that a new object has entered the search area and activates the sensor. The type of sensor deployed depends on the nature of the Read More

The term Video Graphics Array can be used to refer to many different things, but the original usage was by IBM for the graphics standard implemented in their PS/2 computer line. The original IBM VGA standard marketed in 1987 consisted of a 640 pixel by 480 pixel 16-color display at its highest resolution, but also included lower resolutions. Among those alternate modes, the 320 by 200 pixel 256-color "Mode 13h" was a common resolution for computer games because of the increased range of colors available to developers.

A surge suppressor is a device that protects electrical equipment by dispersing or grounding excess electric current that surges or spikes in the electrical power grid. These surges can occur up to four times a day and can damage electronic equipment that is connected to power outlets throughout a home or office. Lightning, downed power lines, high-frequency sound waves, high-power electrical equipment, and natural weather conditions generally cause surges and spikes. How Surge Suppressors Work A surge suppressor is a ceramic or metal cylinder that is filled with oxygen in Read More

A ferrofluid is a metallic liquid that becomes magnetized when placed in a magnetic field. Ferrofluids are made up of clumps of iron nanoparticles that are evenly placed throughout a carrier fluid such as water or organic solvent. These clumps all work together to create a response to a magnetic field, consequently creating a very strong magnetic bond. Ferrofluids should not be confused with magnetorheological fluids, which solidify when exposed to a magnetic field. How a Ferrofluid Works Ferrofluids are made up of clumps of nanoscale particles of a metal Read More
