Technology ("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia) is the sum of techniques, skills, methods, and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge of techniques, processes, and the like, or it can be embedded in machines to allow for operation without detailed knowledge of their workings. Systems (e.g. machines) applying technology by taking an input, changing it according to the system's use, and then producing an outcome are referred to as technology systems or technological systems.
The simplest form of technology is the development and use of basic tools. The prehistoric discovery of how to control fire and the later Neolithic Revolution increased the available sources of food, and the invention of the wheel helped humans to travel in and control their environment. Developments in historic times, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale.

The Sholes and Glidden typewriter (also known as the Remington No. 1) was the first commercially successful typewriter. Principally designed by the American inventor Christopher Latham Sholes, it was developed with the assistance of fellow printer Samuel W. Soule and amateur mechanic Carlos S. Glidden. Work began in 1867, but Soule left the enterprise shortly thereafter, replaced by James Densmore, who provided financial backing and the driving force behind the machine's continued development. After several short-lived attempts to manufacture the device, the machine was acquired by E. Remington and Sons in early 1873. An arms manufacturer seeking to diversify, Remington further refined the typewriter before finally placing it on the market on July 1, 1874. Read more...
