Technology is simply the combination of any human abilities, technical know-how, techniques, methods, and procedures utilized in the creation of products or services or in their realization of specific goals, for example scientific research. It also refers to the systems and devices that are used to implement these human activities. Basically, the study of technology is an attempt to bring order out of chaos, or more precisely, from the various different forces which influence human actions and their interaction. In this regard, there are five technologies that are known to be the primary factors that lead to the progress of mankind. These are communication, transportation, information and communication technology, computer technology, and energy.
Information technology is a branch of science that deals mainly with the transfer of data from one source to another. The most obvious source of such data transfer is of course the physical mediums that surround us. However, it also travels through the internet, which is just a form of electronic communication. With the aid of such mediums as digital cameras, mobile phones, radio, TV, and other forms of communications technologies, people can exchange information across great distances without much hindrance.
Transportation technology refers to the means by which people get from one place to another. It could either be by land or by sea. Transportation technology is also responsible for shipping, which helps in transporting bulk products and other raw materials. Air transportation is another means of transport, which allows for goods to be brought from one place to another.
Information technology is on the other hand, deals mostly with the machine. Examples of this technology include computer technology, telecommunications technology, medical technology, digital media, optical technology, and networking technology. All the machines mentioned above are interconnected through computer networks. This technology is responsible for the generation of electricity, gas, water, and so on. It also produces the means of communication, information, entertainment, and different types of other activities.
The invention of new technology has often had negative effects, especially when it infringes upon the rights of people in other parts of the world. Technological innovations may be dangerous for the overall advancement of the human society, as it encourages war, murder, sexual harassment, and many other bad activities. Sometimes, the introduction of technology may be welcomed, but once it is used too extensively, it can be harmful. This is when the question of human welfare arises.
Technological change can also be good for the advancement of the human societies if it creates more demand for educated people to create new technology. Also, the creation of technology changes the definition of beauty. It can be positive if used for the good, and negative if used for the evil. Nevertheless, this is a big question that has been discussed throughout history, and still continues today.
