In the Air Force, CDC stands for "career development course." Here's how it works: After basic training, you go to technical training to learn how to do your job. Once you graduate, you get a 3-skill level. When you get to your first assignment, they order your CDC materials. Your CDCs are booklets that you have to read and take an ungraded course exam at the end of each booklet. Your supervisor will check your answers, go over the ones you got wrong, and once you finish all your CDCs you'll be scheduled for the end of course exam. You have to score at least 65% to pass. If you pass, and you meet the rest of the requirements, you'll be upgraded to your 5-skill level. Some career fields have CDCs for upgrade to the 7-skill level as well. |

Before you start calling people "retards", you should know that not everyone in the military has CDCs.
The Navy does not use them, as I have never seen a CDC in over twenty years of service, active and reserve.
Should I ask you what PQS is?
BTW. The Centers for Disease Control is far more well known than Air Force training guides. |

Control Data Corporation (CDC), was one of the pioneering supercomputer firms. For most of the 1960s, it built the fastest computers in the world by far, only losing that crown in the 1970s to what was effectively a spinoff. CDC was one of the eight major computer companies through most of the 1960s; the others were IBM, Burroughs Corporation, NCR, General Electric, Honeywell, RCA, and UNIVAC. CDC was well known and highly regarded throughout the industry at one time, but today is largely forgotten.
CDC started business by selling subsystems, mostly drum memory systems, to other companies. Mr. Cray joined the next year, and he immediately built a small transistor-based 6-bit machine known as the "CDC Little Character" to test his ideas on large-system design and transistor-based machines. "Little Character" was a success, and CDC soon released a 48-bit transistorized version of their 1103 re-design as the CDC 1604 in 1959, with the first machine delivered to the U.S. Navy in 1960. The 1604 designation was chosen by adding the number, 501, in CDC's address, 501 Park Avenue, to the number of Cray's former project, the 1103. A 12-bit cut-down version was also released as the CDC 160A in 1960, arguably the first minicomputer. The 160A was particularly notable as it was built as a standard office desk item, which was a rather-unusual packaging for that era. New versions of the basic 1604 architecture were rebuilt into the CDC 3000 series, which sold through the early and mid-1960s.
Mr. Cray immediately turned to the design of a machine that would be the fastest (or in the terminology of the day, largest) machine in the world, setting the goal at 50 times the speed of the 1604. This required radical changes in design, and as the project "dragged on" --it had gone on for about four years by then--, the management got increasingly upset and it demanded greater oversight. Cray in turn demanded (in 1962) to have his own remote lab, saying that otherwise, he would quit. Norris agreed, and Cray and his team moved to Cray's home town, Chippewa Falls, Wisconsin. Not even Bill Norris, the founder and president of CDC, could visit Cray's laboratory without an invitation. (See story of a salesman's uninvited visit to Chippewa Falls |
