Technology is the practical application of scientific knowledge and principles.  While technology can be represented in physical form (patents, procedures, design documents, manuals, etc.), it is not a physical entity. It is the knowledge of how scientifically determined facts and principles are embodied in the material, device, product, or process.

A technological advancement is an attempt at extending or further understanding the underlying science used to develop current materials, devices, products or processes.

Technology affects the way individuals communicate, learn, and think. It helps society and determines how people interact with each other on a daily basis. Technology plays an important role in society today. ... We are living in an era where technological advances are common.

History of technology, the development over time of systematic techniques for making and doing things. The term technology, a combination of the Greek technē, “art, craft,” with logos, “word, speech,” meant in Greece a discourse on the arts, both fine and applied. When it first appeared in English in the 17th century, it was used to mean a discussion of the applied arts only, and gradually these “arts” themselves came to be the object of the designation. By the early 20th century the term embraced a growing range of means, processes, and ideas in addition to tools and machines. By mid-century technology was defined by such phrases as “the means or activity by which man seeks to change or manipulate his environment.” Even such broad definitions have been criticized by observers who point out the increasing difficulty of distinguishing between scientific inquiry and technological activity.

On July 26, 1775, the U.S. postal system is established by the Second Continental Congress, with Benjamin Franklin as its first postmaster general. Franklin (1706-1790) put in place the foundation for many aspects of today’s mail system

The mail or post is a system for physically transporting postcards, letters, and parcels. A postal service can be private or public, though many governments place restrictions on private systems.

A typewriter is a mechanical device to produce printed characters on a piece of paper by typing individual keys. Introduced in the 1870s, they become widely used for business communications up until the rise of modern day personal computers in the 1980s.

Christopher Latham Sholes is given credit for inventing the first "practical" typewriter. He was in fact the fifty-second person or possibly the 112th to reinvent a "type-writing" machine – which he called a type-writer.

A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user.

It was at this time, 1876–1877, that a new invention called the telephone emerged. It is not easy to determine who the inventor was. Both Alexander Graham Bell and Elisha Gray submitted independent patent applications concerning telephones to the patent office in Washington on February 14, 1876.

A system for transmitting visual images and sound that are reproduced on screens, chiefly used to broadcast programs for entertainment, information, and education.

Philo Farnsworth, in full Philo Taylor Farnsworth II, (born August 19, 1906, Beaver, Utah, U.S.—died March 11, 1971, Salt Lake City, Utah), American inventor who developed the first all-electronic television system.

The Internet is a vast network that connects computers all over the world. Through the Internet, people can share information and communicate from anywhere with an Internet connection.

ThatThat year, a computer programmer in Switzerland named Tim Berners-Lee introduced the World Wide Web: an internet that was not simply a way to send files from one place to another but was itself a “web” of information that anyone on the Internet could retrieve. Berners-Lee created the Internet that we know today.

The first edition of radio was patented in 1896 by Guglielmo Marconi. Marconi was a pioneer of wireless telegraphy. Born in Italy in 1874, he began experimenting with his inventions at the age of 20 after becoming aware of the work of Hertz in electromagnetic waves, also known as radio waves.

Radio technology, transmission and detection of communication signals consisting of electromagnetic waves that travel throughthe air in a straight line or by reflection from the ionosphere or from a communications satellite.

Developed in the 1830s and 1840s by Samuel Morse (1791-1872) and other inventors, the telegraph revolutionized long-distance communication. It worked by transmitting electrical signals over a wire laid between stations. In addition to helping invent the telegraph, Samuel Morse developed a code (bearing his name) that assigned a set of dots and dashes to each letter of the English alphabet and allowed for the simple transmission of complex messages across telegraph lines.

A camera is an optical instrument used to capture an image. At their most basic, cameras are sealed boxes with a small hole that allows light in to capture an image on a light-sensitive surface. Cameras have various mechanisms to control how the light falls onto the light-sensitive surface.

Johann Zahn designed the first camera in 1685. But the first photograph was clicked by Joseph Nicephore Niepce in the year 1814. It was thousands of years back that an Iraqi scientist Ibn- al- Haytham made a mention of this kind of a device in his book, Book of Optics in 1021.

A personal computer is a general-purpose computer whose size, capabilities and original sale price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer operator. ... A personal computer may be a desktop computer or a laptop,netbook, tablet or a handheld PC.

Analytical Engine, generally considered the first computer, designed and partly built by the English inventor Charles Babbage in the 19th century (he worked on it until his death in 1871).

The very first mobile phones were not really mobile phones at all. They were two-way radios that allowed people like taxi drivers and the emergency services to communicate.

Instead of relying on base stations with separate cells (and the signal being passed from one cell to another), the first mobile phone networks involved one very powerful base station covering a much wider area.

Motorola, on 3 April 1973 were first company to mass produce the the first handheld mobile phone.

The cellphone has changed drastically from when the original cell phone (aka bricks) was released. Below is a picture of a very early cell phone, the more modern Nokia 6010 cell phone in the center, and the more modern iPhone. New cell phones are much lighter than the old brick cell phones, smaller, and have large screens to display contacts and phone settings.
