Technology Changes
Ten years ago I bought a second hand computer set for 15,000 pesos. It was a reliable computer to be used for office applications and light computer games. A Pentium S desktop having a memory of less than a gigabyte.
Today I could purchase at the same amount a brand new system unit which speed is 10-20 times faster than that PC and has memory of 30 more times. Technology changes, its acceleration is faster than an old man learning how to use them.
Ever since men has trying to make human life more easy and comfortable, thus we become superior in all God’s creation.
From the beginning of trade people always find ways that commerce, counting, and calculating would be more easy. The abacus was created, a calculating tool used primarily in parts of Asia for performing arithmetic processes.
During the industrial revolution many inventions of calculating devices have been used and improved. The difference engine and the analytical engine created by Charles Babbage were one of the great inventions of those days. A video from youtube tells the invention, please watch.
During the word war II the Germans, the proponent of the war, were trying to take the advance in the use of weapons and communication technology, since communication plays the vital role in winning the war the Enigma was created to send coded messages. The British, who first received the attack, did not hesitate to find ways to bring down the opponent. The Colossus was created by the British government a counter technology for the enigma.

The Americans were also interested in warfare technology. They created the ENIAC, designed to calculate artillery firing for the United States Army’s Ballistics, but its first use was in calculations for the hydrogen bomb. From that experience they develop other technologies like the GPS (Global Positioning System) tracks enemies’ location and others.
Nowadays, the Americans also have stepped up to use the cyber weapons. Instead of risking planes to bomb power grids, telephone, exchanges rail roads, they envision soldiers at a computer terminal silently invading foreign networks to shut down electrical facilities, interrupt communication, crash trains and disrupt financial systems.
Who knows that modern wars between nations could happen in internet cafes.
