A semiconductor device is an electronic component that relies on the electronic properties of a semiconductor material (primarily silicon, germanium, and gallium arsenide, as well as organic semiconductors) for its function. Its conductivity lies between conductors and insulators. Semiconductor devices have replaced vacuum tubes in
ISTE also offers a certification program (ISTE Certification) aligned to the Standards. The certification program is a competency-based model where educators submit artifacts showing their ability to use technology to support learning. Upon successful completion of a peer-review process, educators are considered "ISTE Certified"
Computers in the classroom include any digital technology used to enhance, supplement, or replace a traditional educational curriculum with computer science education. As computers have become more accessible, inexpensive, and powerful, the demand for this technology has increased, leading to more frequent use of computer resources within ...
Technology integration is defined as the use of technology to enhance and support the educational environment. Technology integration in the classroom can also support classroom instruction by creating opportunities for students to complete assignments on the computer rather than with normal pencil and paper.

A semiconductor is a material that is between the conductor and insulator in ability to conduct electrical current. [1] In many cases their conducting properties may be altered in useful ways by introducing impurities ("doping") into the crystal structure.
In 2021, the sales of semiconductors reached a record $555.9 billion, up 26.2 percent, with sales in China reaching $192.5 billion, according to the Semiconductor Industry Association. A record 1.15 trillion semiconductor units were shipped in the calendar year. [13] The semiconductor industry is projected to reach $726.73 billion by 2027. [14]
The study of semiconductors led to the invention of the diode and the transistor, which are indispensable parts of modern electronics systems, computer and telecommunications devices. Another application is for making laser diodes and light-emitting diodes, which are a high-efficiency source of light.
