An electronic circuit with about 20 transistors fabricated on a silicon chip is known as

A)

MSI

B)

SSI

C)

RJE

D)

DPS

Correct Answer : SSI

An electronic circuit with about 20 transistor fabricated on a silicon chip is known as SSI.

An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or "chip") of semiconductor material, normally silicon.

The term "large scale integration" (LSI) was first used by IBM scientist Rolf Landauer when describing the theoretical concept; that term gave rise to the terms "small-scale integration" (SSI), "medium-scale integration" (MSI), "very-large-scale integration" (VLSI), and "ultra-large-scale integration" (ULSI).

SSI stands for Supplemental Security Income. Social Security administers this program. We pay monthly benefits to people with limited income and resources who are disabled, blind, or age 65 or older. Blind or disabled children may also get SSI.
