Electronics is a branch of science that deals
with the emission of electrons from
conductors and semiconductors, with the
subsequent manipulation of these electrons,
and with the construction of electronic
devices. The first electronic device was the
thermionic valve, or vacuum tube, in which
electrons moved in a vacuum, and led to such
inventions as radio, television, radar, and
the digital computer. Replacement of valves
with the comparatively tiny and reliable
transistor from 1948 revolutionized
electronic development. Modern electronic
devices are based on minute integrated
circuits (silicon chips), wafer-thin crystal
slices holding tens of thousands of
electronic components.
