Technology Changes in past,present and future
Technology changes start from the beginning of a universe. Before going to the main topic let’s see what is technology.
Technology can be defined as methods, that ranging from as simple as language and stone tools to the complex genetic engineering and information technology. In simple way we defined it as the branch of knowledge dealing with engineering or applied sciences.
Technology changes in past
The period of technological changes is not new. As long as there have been people, there has been technology. It starts from Paleolithic – the bulk of the Stone Age. At the period of stone age, human used limited tools for the fulfilment of their needs. At this period, they gradually do improvement in tools. At this time technological made in the filed of survival, hunting, and food preparation. Stone tools and weapons, fire, and clothing were technological developments of major importance during this period.
After the period of stone age comes copper and bronze ages. At this period, changes are made in agricultural technology that included a development of agriculture, animal domestication, and the adoption of permanent settlements.
Iron age is another golden period of technological changes in past. At this period human being tired to discover tools and technology that are cheap as compared to copper and bronze. At this period introduced iron smelting technology. It generally replaced bronze and made it possible to produce tools which were stronger, lighter and cheaper to make than bronze equivalents.
Technological changes in past passing through various periods. Ancient civilizations produced the greatest advances in technology and engineering. After that, Egyptians invented and used many simple machines, such as the ramp to aid construction processes.
Chines also play the vital role in the advancement in technology. They contributed to seismological detectors, matches, paper, sliding calipers, the double-action piston pump, cast iron, the iron plough, the multi-tube seed drill, the wheelbarrow, the suspension bridge, the parachute, natural gas as fuel, the compass, the raised-relief map, the propeller, the crossbow, the South Pointing Chariot and gunpowder technology.
Greek and Roman also the paly important role to the advancement of technological changes with the passage of time. The period of Greek and Roman is also considered early technological changes period. Ancient Greek technology innovations were particularly pronounced in mechanical technology, including the ground-breaking invention of the watermill which constituted the first human-devised motive force not to rely on muscle power.
Technology changes in present time
We can say that 20th and 21st century is a present period of technology. In 20th century technology developed rapidly. Broad teaching and implementation of the scientific method, and increased research spending contributed to the advancement of modern science in the present period. Present technology has improved communication and transport system.

Technology changes in future
Technology in future become more advance. We can take idea our past and present situation of technology. Technology is changing rapidly. Technology in next future years most impact on Internet of the things(IoT). It makes our life more and easier. Everything becomes automated. A to Z all thing become automatic. In automation of technology, Internet will play very important role. In next few year, new technology Li-Fi will take the place of wi-fi. This technology provides the fastest speed of internet as compared to wi-fi.
SmartThings is also the new form of technology. SmartThings is to make your every device, digital or non-digital, connect together and benefit you. Most important innovation brings open source in future. The concept of commercialization will change. You can get more and more benefits through open source products.
