solid state

[′säl·əd ′stāt]
(engineering)
Pertaining to a circuit, device, or system that depends on some combination of electrical, magnetic, and optical phenomena within a solid that is usually a crystalline semiconductor material.
(physics)
The condition of a substance in which it is a solid.

solid state

(electronics)
(Often hyphenated when used as an adjective) A term describing any device that uses semiconductor components rather than electron tubes or relays. Semiconductors are "solid" in that they contain no gas ("vacuum" tubes contain a small amount as the vacuum is not perfect) or moving parts (like relays), but probably more important is the connotation of reliability and durability that made possible things like portable radios.

solid state

Non mechanical. Solid state refers to electronic circuits composed of transistors, resistors, capacitors and other components, which may be discrete, single devices, or millions of them can be created in a single chip. For example, microprocessors and memories are all solid state. In a solid state device, there is no mechanical action, although an unbelievable amount of electromagnetic action takes place within.

A computer has solid state and non-solid state parts. The solid state components are the motherboard, chips, screen, camera and optical mouse, while the hard drive, CD/DVD drive, fans, keyboard, microphone and speakers have mechanical components.

Faster and More Reliable Storage
For data storage, solid state devices are faster and more reliable than mechanical drives that spin disk platters, but they are more expensive. Although the cost of solid state disks is dropping all the time, the cost/performance ratio of magnetic disks continues to improve as well. See SSD.

Ahead of Its Time
Predicting the demise of the hard disk, this message was cut out of a mouse pad from the 1990s that was a bit ahead of its time. However, solid state drives (SSDs) are increasingly replacing spinning platters. See SSD.







All Solid State
A USB drive comprises a controller chip, quartz crystal (large silver component), some discrete resistors and capacitors (R's and C's) and a flash memory chip (bottom). The clear plastic is an LED. See USB drive.
