The motes were powered by a tiny battery and could gain light energy through a photocell, which was enough to feed the infinitesimally small amount of energy a mote consumes . Motes are also known as “smart dust,” since the intention is that their tiny size and low cost make them inexpensive enough to “sprinkle” in the real world to as sensors. An ecologist, for example, could sprinkle thousands of motes from the air onto a field and measure soil and air temperature, moisture, and sunlight, giving them accurate real-time data about the environment.

Software refers to the programs your computer uses to perform the actions you want it to. Learn all about computer software, from Web browsers to the latest operating systems, with our explanations, reviews, videos and prices. They're involved in scientific research and developing empirical understandings of users. Conversely, UX designers are almost invariably industry-focused and involved in building products or services—e.g., smartphone apps and websites. Regardless of this divide, the practical considerations for products that we as UX professionals concern ourselves with have direct links to the findings of HCI specialists about users’ mindsets. With the broader span of topics that HCI covers, UX designers have a wealth of resources to draw from, although much research remains suited to academic audiences.

The US Army asked Bell Laboratories to design a machine to assist in testing its M-9 gun director, a type of analog computer that aims large guns to their targets. Mathematician George Stibitz recommends using a relay-based calculator for the project. The result was the Relay Interpolator, later called the Bell Labs Model II. The Relay Interpolator used 440 relays, and since it was programmable by paper tape, was used for other applications following the war. Using a pen-like stylus, pen-based computers accept handwritten input directly on a screen. Users of the handheld pen-based computers, also called personal digital assistants , like the Palm, enjoy having applications such as calendars, address books, and games readily available. Secondary storage consists of devices, such as diskettes, which can store data and programs outside the computer itself.

A computer is a machine or device that performs processes, calculations and operations based on instructions provided by a software or hardware program. It has the ability to accept data , process it, and then produce outputs. Large-scale distributed systems were first used for scientific and engineering applications and took advantage of the advancements in system software, programming models, tools, and algorithms developed for parallel processing. Modern supercomputers derive their power from architecture and parallelism rather than the increase of processor speed. The supercomputers of today consist of a very large number of processors and cores communicating via very fast custom interconnects.
