We learn from the passage that many of the newest and fastest supercomputers ----.
From its birth during World War II, there is one task
to which cutting-edge computer technology has
always been applied: code-breaking. In 1943,
mathematicians and engineers at Bletchley Park,
Buckinghamshire, built Colossus, the forerunner of
the modern electronic computer. Its task was to
break the Lorentz ciphers, used by Hitler and his
generals for their most secret communications.
Consisting of thousands of valves, optical devices
and pulleys, Colossus looked ungainly but worked
brilliantly. One of its major triumphs was to reveal
that Hitler had been taken in by Allied deception
tactics leading up to D-Day, thus clearing the way for
the real invasion in 1944. Ever since, government
code-breaking centers have bought the fastest
supercomputers the moment they emerge, During
the Cold War, the key challenge was to find and
exploit the slightest weakness in the cipher systems
used by the Soviet Union, acknowledged to be the
most secure in the world. Their efforts ultimately led
to the downfall of all of the Soviet's "Magnificent Five"
British spies.
