Physical technology

Physical Technology

Physical technology describes all tools, machinery and gadgets used both within industry and by consumers. This includes anything from a simple hammer or the hardware within a computer to highly sophisticated machinery used in industry, medical settings, aviation, research of all types etc. It also covers transport, environmental and assisting technologies. Its main concern lies within the physical tools used to assist in performing an action or achieving a specific purpose.

Information technology

Information Technology

This type of technology has evolved out of a combination of science and physicaltechnologies. Specific areas within information technology are, for instance, communications technology; computer technology, or to be more specific, computer software and educationaltechnology. The main concern of information technology is to create, store and transmit information from one individual or group to another, often over great distances.

There are many different views regarding types of technology, and definitions are likely to vary, but hopefully this post will be of some help

Electronic technology.

Electronics is the science of controlling electrical energy electrically, in which the electrons have a fundamental role. Electronics deals with electrical circuits that involve active electrical components (such as vacuum tubes, transistors, diodes, integrated circuits, optoelectronics, and sensors), associated passive electrical components, and interconnection technologies. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit.

The science of electronics is considered to be a branch of physics and electrical engineering.[1][2]

The nonlinear behaviour of active components and their ability to control electron flows makes amplification of weak signals possible. Electronics is widely used in information processing, telecommunication, and signal processing. The ability of electronic devices to act as switches makes digital information processing possible. Interconnection technologies such as circuit boards, electronics packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed components into a regular working system.

Electronics is distinct from electrical and electro-mechanical science and technology, which deal with the generation, distribution, switching, storage, and conversion of electrical energy to and from other energy forms using wires, motors, generators, batteries, switches, relays, transformers, resistors, and other passive components. This distinction started around 1906 with the invention by Lee De Forest of the triode, which made electrical amplification of weak radio signals and audio signals possible with a non-mechanical device. Until 1950 this field was called "radio technology" because its principal application was the design and theory of radio transmitters, receivers, and vacuum tubes.

Today, most electronic devices use semiconductor components to perform electron control. The study of semiconductor devices and related technology is considered a branch of solid-state physics, whereas the design and construction of electronic circuitsto solve practical problems come under electronics engineering. This article focuses on engineering aspects of electronics.

Educational technology.

Educational technology is "the study and ethical practice of facilitating learning and improving performance by creating, using, and managing appropriate technological processes and resources".[1]

Educational technology is the use of both physical hardware and educational theoretics. It encompasses several domains, including learning theory, computer-based training, online learning, and, where mobile technologies are used, m-learning. Accordingly, there are several discrete aspects to describing the intellectual and technical development of educational technology:

educational technology as the theory and practice of educational approaches to learningeducational technology as technological tools and media that assist in the communication of knowledge, and its development and exchangeeducational technology for learning management systems (LMS), such as tools for student and curriculum management, and education management information systems (EMIS)educational technology as back-office management, such as training management systems for logistics and budget management, and Learning Record Store (LRS) for learning data storage and analysis.educational technology itself as an educational subject; such courses may be called "Computer Studies" or "Information and communications technology (ICT)".

An educational technologist is someone who is trained in the field of educational technology. Educational technologists try to analyze, design, develop, implement and evaluate process and tools to enhance learning.[2] While the term educational technologist is used primarily in the United States, learning technologist is synonymous and used in the UK[3] as well as Canada.

Medical technology.

MEDICAL TECHNOLOGY 

The field of medicine continues to amaze us with the advances constantly being made in medical technology. In addition to seemingly miraculous surgical procedures that are technology-based, many individuals are dependent upon medical technology to stay alive or otherwise enable people to function outside of hospitals and other medical settings. It is not uncommon to see people in their home and community settings who use medical technology.

For example, artifical limbs and hip and knee implants can help people function in the environment. Cochlear implants can often improve the hearing of people with auditory nerve damage. Some devices provide respiratory assistance through oxygen supplementation and mechanical ventilation. Others, such as cardiorespiratory monitors and pulse oximeters are used as surveillance devices that alert an attendant to a potential vitality problem. Nutritive assistive devices can assist in tube feeding or elimination through ostomies. Intravenous therapy can be provided through medication infusion and kidney function can be assumed by kidney dialysis machines (Batshaw & Perret, 1992). In addition to keeping people alive, technologies such as these can enable people to fully participate in school, community, and work activities.MEDICAL TECHNOLOGY
