Information Technology

The telegraph was created in the early 1800s.Morse code was created by Samuel Morse in 1835. The telephone (one of the most popular forms of communication ever) was created by Alexander Graham Bell in 1876. The first radio developed by Guglielmo Marconi in 1894. The first large-scale automatic digital computer in the United States was the Mark I created by Harvard University around 1940.

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.

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.

Premechanical(3ooo B.C.)

The ENIAC was the first high-speed, digital computer capable of being reprogrammed to solve a full range of computing problems.There are 4 main sections of digital computing:The first was the era of vacuum tubes and punch cards like the ENIAC and Mark I.The second generation replaced vacuum tubes with transistors.The third generation replaced transistors with integrated circuits. The fourth and latest generation brought in CPUs (central processing units) which contained memory, logic, and control circuits all on a single chip.

Evolution

There are 4 main ages that divide up the history of information technology. And some of them really affects us today, so that it is important to learn about how we got to the point we are at with technology today.

Mechanical(1450 to 1840)

Electromechanical(1840 and 1940)

Let´s go back in the history

Electronic(1940 to now)

Let´s see a timeline
