What term is defined as the use of knowledge, tools, and ideas to improve living conditions and work efficiency?

The term that refers to the use of knowledge, tools, and ideas to improve living conditions and work efficiency is technology. Technology encompasses a broad range of practices and applications that help enhance various aspects of human life. It includes everything from machinery and systems to software and methods that enable more efficient processes or better living standards.

This definition aligns closely with the idea that technology not only seeks to introduce new tools but also aims to improve functionality and usability in our daily lives and workplaces. The emphasis on improving living conditions and work efficiency demonstrates technology's role in fostering innovation and practicality in various fields.

While engineering is a discipline that often applies scientific and mathematical principles to design and build solutions, it is more specific to the creation of structures, machines, and systems rather than the broader application of ideas and tools found in technology. Science is focused on the study and understanding of the natural world through observation and experimentation, while innovation refers to the introduction of something new or improvement of existing ideas and practices. These concepts are somewhat related, but they do not capture the full scope of what technology represents in enhancing efficiency and quality of life.
