Modern Computers May Have Originated From the WWII Enigma Cypher Machine
During World War II, British mathematician Alan Turing, along with a team of people at Bletchley Park in Britain, developed a machine capable of breaking the German Enigma code. Enigma was Germany’s principal encryption device during the war and was considered unbreakable. The project was code named: ULTRA. At the time, the Enigma code was considered unbreakable. The machine developed was called Colossus. Colossus was comprised of vacuum tubes (British call them valves), telephone stepper relays, a paper tape reader, and circuits, which could be changed, to enable Bletchley Park to decode parts of the Enigma machines messages. The Enigma messages were transmitted in blocks of Morse code characters, but scrambled into billions of different combinations of Morse Code characters by rotors inside the Enigma machines. This project is considered by some to have been the beginning of today’s modern computers.
Today, computers are everywhere. They are in our homes, cars, offices, and even our pockets, in the form of cellphones. Most of the time they work and perform very useful tasks, and enrich our lives. Once in a while, they malfunction and cause us grief. Some of the reasons are below:
Typical Issues With PC’s Today
- Hard Drive Errors (head crashes, etc.)
- Out of Hard Drive Space
- Virus, Spyware, Ransomware, Malware
- Computer Crashes (blue screen of death)
- Temperature Issues (fan failure)
- RAM (memory card) Defective
- Graphics Card Defective
- Power Supply Failure
- Corrupted Software
