An open case of a steam turbine. Today, most of the electricity is generated by these turbines. Living standards and electricity use are closely related. The development of electrification is regarded as the greatest significant engineering feat of the 20th century. The term “technology” (Greek:, techne, “art, skill, cleverness of hand”; and -o, -logia) refers to the collection of techniques, skills, methods, and procedures employed in the creation of goods and services as well as the achievement of goals, such as scientific research. Technology can be the understanding of methods, procedures, and the like, or it can be a feature built into machinery that enables use without intimate knowledge of how they function. Technology systems or technical systems are machines or other systems that employ technology to take an input, modify it to suit the system’s needs, and then produce an output.

The creation and use of fundamental tools constitutes the most basic type of technology. The Neolithic Revolution and the earlier discovery of how to regulate fire boosted the amount of food that was accessible, and the development of the wheel made it easier for humans to move about and control their surroundings. The printing press, the telephone, and the internet are examples of historical developments that have lowered physical barriers to communication and enabled people to freely communicate on a global scale.
