What are the major events that led to the development of modern electronic systems?

The development of modern electronic systems can be traced back to the discovery of the electron in 1897 by J.J. Thomson. This discovery led to a series of innovations and inventions that revolutionized the field of electronics. Here are some major events that led to the development of modern electronic systems:

• 1904: John Ambrose Fleming invents the vacuum tube, which is used to amplify signals in electronic circuits.
• 1926: Julius Lilienfeld patents the first field-effect transistor, which is the basis for modern electronics.
• 1947: William Shockley, John Bardeen, and Walter Brattain invent the point-contact transistor, which is the first transistor to be used in practical applications.
• 1958: Jack Kilby invents the integrated circuit, which combines multiple components into a single chip.
• 1965: Gordon Moore, co-founder of Intel Corporation, observes that the number of transistors on a chip doubles roughly every 18 months. This observation is known as Moore's Law and has become a guiding principle of the electronics industry.

These major events led to the development of the modern electronic systems that we use today. From radios and televisions to computers and smartphones, electronics have become an integral part of our daily lives.
