Basically as long as people have been around, information technology has been around because there were always ways of communicating through technology available at that point in time. There are 4 main ages that divide up the history of information technology. Only the latest age electronic and some of the electromechanical age really affects us today, but it is important to learn about how we got to the point we are at with technology today.
It can be defined as the time between B. We are talking about a long time ago. When humans first started communicating they would try to use language or simple picture drawings known as petroglyths which were usually carved in rock. Early alphabets were developed such as the Phoenician alphabet.
Petroglyph As alphabets became more popluar and more people were writing information down, pens and paper began to be developed. It started off as just marks in wet clay, but later paper was created out of papyrus plant.
The most popular kind of paper made was probably by the Chinese who made paper from rags. Now Introduction to media technology people were writing a lot of information down they needed ways to keep it all in permanent storage.
This is where the first books and libraries are developed. Some groups of people were actually binding paper together into a book-like form.
Also during this period were the first numbering systems. And yes now that numbers were created, people wanted stuff to do with them so they created calculators. A calculator was the very first sign of an information processor.
The popular model of that time was the abacus. The mechanical age can be defined as the time between and A lot of new technologies are developed in this era as there is a large explosion in interest with this area. Technologies like the slide rule an analog computer used for multiplying and dividing were invented.
Blaise Pascal invented the Pascaline which was a very popular mechanical computer. Charles Babbage developed the difference engine which tabulated polynomial equations using the method of finite differences.
Difference Engine There were lots of different machines created during this era and while we have not yet gottent to a machine that can do more than one type of calculation in one, like our modern-day calculators, we are still learning about how all of our all-in-one machines started.
Also, if you look at the size of the machines invented in this time compared to the power behind them it seems to us absolutely ridiculous to understand why anybody would want to use them, but to the people living in that time ALL of thse inventions were HUGE.
The electromechanical age can be defined as the time between and These are the beginnings of telecommunication. The telegraph was created in the early s.
Morse code was created by Samuel Morse in The telephone one of the most popular forms of communication ever was created by Alexander Graham Bell in The first radio developed by Guglielmo Marconi in All of these were extremely crucial emerging technologies that led to big advances in the information technology field.
The first large-scale automatic digital computer in the United States was the Mark 1 created by Harvard University around This computer was 8ft high, 50ft long, 2ft wide, and weighed 5 tons - HUGE. It was programmed using punch cards.A functionalist would probably focus on what social purposes technology and media serve.
For example, the web is both a form of technology and of media, and it links individuals and nations in a communication network that facilitates both small family discussions and global trade networks. An attempt to define media and technology, and to consider the educational foundations for use.
Introduction to Digital Technology is the foundational course for Web & Digital Communications, Programming, Advanced Programming, Information Support & Services, and Network Systems pathways.
Technology can be a powerful tool for transforming learning. It can help affirm and advance relationships between educators and students, reinvent our approaches to learning and collaboration, shrink long-standing equity and accessibility gaps, and adapt learning experiences to meet the needs of all learners.
