The word “technology” comes from the Greek words “techn” (which pertains to arts or crafts) and “logia” (which pertains to the study). The combination of these two words, technology, means systematic treatment.
Over the past two centuries, the use of the word “technology” has changed significantly. By the 1940s, “technology” referred not only to the study of the industrial arts, but to include all machines, tools, equipment, weapons, communication and transportation devices as well as the skills by which humans use them. manufacture and use.
Broadly speaking, technology refers to a collection of tools, machines, and techniques that can be used to solve real-world problems. Tools and machines can be as simple as nail pins or as complex as particle accelerators or space stations. Plus, they don’t need to be physical;
Virtual technology, such as software and cloud services, falls under this definition of technology.
Broadly Speaking, Technology Is A Means To Fulfill Human Purpose.
Since technology can be so simple or extremely complex, it can be classified into different groups. Below we have explained all the different types of technology with modern examples.

Materials technology is a broad discipline that involves selecting materials with properties that best meet the requirements of a target application. It may also include maintaining the performance of the material by resisting fatigue, corrosion and other damages during the life of the machine.
Since different materials have different properties, the blending of multiple materials yields interesting features, leading to new applications.
Recent advances in materials technology lend additional functionality to the term “smart materials”, which characterize their response to certain external stimuli such as light, humidity and temperature. Many innovative materials such as carbon nanotubes, graphene and piezoelectric materials have been successfully developed and tested over the past decade.
Materials science and materials technology are closely related to each other. Whereas the former covers the design and discovery of new materials (especially concrete), materials technology focuses more on techniques and tests to determine how to improve the product.
Applications: Cars built using mechanical robots, 3D printers, power plants
Mechanical technology deals with the techniques of holding mechanical parts and materials together to form functional structures and to control or transmit motion. For example, brakes on bicycles, latches on doors, gear systems in car transmissions, etc.
Mechanical engineering technologists are expected to apply principles from product design, materials science and manufacturing processes to create useful products and production machinery.
They primarily work as troubleshooters in the ongoing maintenance of machinery and automatic equipment.
More specifically, his work includes stresses, stresses, shear forces, bending, bearing, clutches, dynamics of a rigid body, motion, balance of rotating masses, free vibrations, flow of fluids, due to the thermodynamic behavior of real Includes deflection analysis. liquids, and much more.
Applications: stethoscope, pacemaker, ventilator, computed tomography (CT) scanner, surgical robot
Medical technology is often defined as the application of science to create solutions to prevent disease, injury, or other health problems. This may include detection of diseases through advanced machines, methods of treatment of patients and monitoring of good health.
In the broadest sense, medical technology focuses on equipment, systems, facilities, and processes (but not on drugs). A medical device can be a device, instrument, instrument, implant, reagent, or software.
From syringes and sphygmomanometers (a device for measuring blood pressure) to medical imaging techniques (such as X-rays and MRI machines), medical machines can play many roles in the diagnosis, prevention, monitoring, treatment, and eradication of disease.
One of the major technological advances in healthcare is 3D printing. It is used to make specialized prostheses, splints, parts for inert implants as well as customized replaceable body parts.

Over the past decade, robotics has made a significant contribution to healthcare. Robots can assist doctors in performing various difficult tasks. surgicalThe robotic arm allows surgeons to bend and move tissues in a more flexible and efficient manner.
Applications: Computers, Smartphones, Digital Cameras, Radars (Radio Detection and Ranging), Electricity Suppliers, Multimeters, Interactive Sensors
Electronics deals with everything that involves the emission, flow and control of electrons in vacuum and matter. An electronic component can be any physical unit in a system (such as capacitors, resistors, inductors, diodes and transistors) that carries electrons or their associated fields to suit the intended operation of the electronic system.
Electronics mainly include passive and active components, solid-state devices, operational amplifiers, audio and radio-frequency amplifiers, oscillators, frequency modulators, digital circuits, digital circuits, power supplies and optoelectronics devices such as solar cells, light-emitting diodes Are included. and optical fiber.
This has made possible the development of a wide range of electronic consumer, military and industrial products.
By 2021, most electronic devices will use semiconductors to perform electron control. In fact, these devices represent a large part of modern technology.
Integrated silicon circuits can be found everywhere, including in everyday home appliances, cars and even satellites. They are used extensively in telecommunications, signal processing and information processing.
Applications: LAN (Local Area Network), Video Text, Teletext, Internet, Wireless Information Transfer, GPS
Communication technology involves converting audio-visual and telephone networks with computer networks through an integrated system of cabling or links.
Network enhancements come from recent advances in computing devices, some of which have been specifically developed to convert network applications and data from one point to another.
It is a broad and constantly evolving field, covering all devices for receiving, storing, retrieving, processing, transmitting information electronically in digital form. This includes radio, television, mobile phones, communication equipment, satellite systems, as well as many different services.
Communication technology is, in fact, an important part of IT infrastructure. It makes it possible to exchange, transfer and provide information through private or public networks. It also enables better management of e-resources and thus, quality services.
In addition, this technology is used extensively in space. For example, NASA and agencies use free-space optical communications in outer space to transfer more data in less time.
