the use of modern transistors in electronics such as amplifier circuits.

Electronic devices, like transistors or crystals, which can control current without the use of moving parts, heated filaments, or vacuum gaps.

Electronic circuits comprised of transistors and integrated circuits, rather than vacuum tubes.

consisting of semiconductor materials and components and related devices

No moving parts. Solid-state memory, in contrast to hard disks with several moving parts, is inherently more durable.

In electronics, consisting chiefly of semiconductor devices and related components.

A field of electronics that uses semiconductor materials and has no moving parts. It requires less power than conventional systems.

Any element that controls current without moving parts, heated filaments, or vacuum gaps.

Any electrical circuit built without electro mechanical parts such as tubes (valves). Transistor circuitry.
