Technology is the combination of any new methods, skills, systems, or processes used in the creation of new products or services or in their achievement of specific objectives, like scientific research. Some sectors that use technology are telecommunications, information technology, engineering, computer science, electrical engineering, software engineering, and physical sciences. The development of new products and services often require the use of new technology. Many processes in daily life require the application of technology, like the use of machinery to create products or to do physical work, the development of new medical equipment, or even the design of new infrastructure.
There are three main categories of tech industries. The first is information technology, which includes computer science, engineering, and applied software engineering, and includes computer technology, computer systems engineering, information management, networking, software, hardware, and networking. These fields all are involved in creating, building, and maintaining computer systems and often rely heavily on information technology. The second category is healthcare, which is the largest part of the tech industry. This field incorporates a wide variety of technologies, including bio-medical technologies, cognitive science, and other areas. The third category is environmental technologies, which involves a broad range of technologies that are used to help solve problems for improving the quality of the environment and to prevent environmental issues, from minimizing the effects of harmful emissions to addressing climate change.
Another growing tech industry is in Big Data, which is essentially the study of vast sets of data, often gathered into large databases. These can include satellite images, census records, or any other source that holds information. Large tech companies like Apple and IBM have been using big data to power a variety of their operations, from helping doctors analyze data about disease symptoms to offering online shopping. Some tech companies like ZaaZoom! Inc., however, are attempting to buck the trend and offer an iPhone application that solves some of the same problems as many of the big data tech companies.
