MEANING OF TECHNOLOGY

The term is derived from the Greek words tekhnē, which refers to an art or craft, and logia, meaning an area of study. Thus, technology means literally, the study or science of crafting. Technology can be defined as the processes (methods) and products (materials) that make life easy and stress free.  It is also the application of acquired systematic and scientific knowledge in the development of tools and machines by people to enable them to provide various needs.

Technology is the general term for the processes by which human beings fashion tools and machines to increase their control and understanding of the material environment.

Technology is the study, development, and application of devices, machines, and techniques for manufacturing and production processes.

Technology   is also a method or methodology that uses technical knowledge or tools.

PRODUCTS OF TECHNOLOGY

The use of hoes and cutlass has been replaced by the use of tools and machines powered by steam, water, wind, electricity and sun.

Product of technology refers to the materials, machines and equipment that are used to make life easier. They are the finished products of engineering works; the tools used to achieve specific objectives.  Examples of products of technology are pressing iron, tractor, G.S.M / cell phone, air conditioner, grinding machine, gas cooker, washing machine, electric bulb e.t.c
