Electronics technology


Electronics technology based on vacuum tube circuits improved gradually in the first half of the 20th century and opened the door for many new applications, including radar, electronic navigation, long distance telephony and television. Early advances in electronics also made possible the demonstration of the first special purpose digital computer by John Vincent Atanasoff at the University of Iowa in 1939. Shortly after came dramatic advances in solid state devices with the invention of the transistor by W. Shockley, J. Bardeen and W. Brattain (1948).


In the transistor, the electronic control of current flow takes place inside a semiconductor, a solid state device having the advantages of low power dissipation, high reliability, small package size and low manufacturing costs. This revolutionary invention was followed by creation of the first monolithic integrated circuit by Jack St. Clair Kilby of Texas Instruments (1959).  Nearly at the same time, new ideas were developing in the electronic systems field, including digital signal processing, information theory and the general purpose digital computer in which operating program instructions are stored in memory along with data. 


Solid state technology has proven to be the ideal tool for implementing new ideas in practical electronics equipment, making possible important advances in information processing and communications. From vacuum tubes to transistors to integrated circuits, electronic devices are being made smaller, more powerful and more efficient, making possible many new products that have improved the quality and convenience of modern living.


In the not-too-distant future, the majority of electronic devices will be connected via the Internet or wireless protocols, bringing convenience and simplicity to daily living, but adding layers of technology and complexity to devices we use every day.
