QUES: As computers grew in speed and capability, a number of general-purpose database systems emerged; by the mid-1960s a number of such systems had come into commercial use. Interest in a standard began to grow, and Charles Bachman, author of one such product, the Integrated Data Store (IDS), founded the "Database Task Group" within CODASYL, the group responsible for the creation and standardization of COBOL. In 1971 the Database Task Group delivered their standard, which generally became known as the "CODASYL approach", and soon a number of commercial products based on this approach entered the market.

What was the standard protocol called?
What is the answer?
ANS: CODASYL approach
QUES: However, the problem of deflection settings — 'aim-off' — required knowing the rate of change in the target's position. Both France and UK introduced tachymetric devices to track targets and produce vertical and horizontal deflection angles. The French Brocq system was electrical, the operator entered the target range and had displays at guns; it was used with their 75 mm. The British Wilson-Dalby gun director used a pair of trackers and mechanical tachymetry; the operator entered the fuse length, and deflection angles were read from the instruments.

Which system had electrical tracking?
What is the answer?
ANS: French Brocq
QUES: In 1963, the teenage Brian May and his father custom-built his signature guitar Red Special, which was purposely designed to feedback. Sonic experimentation figured heavily in Queen's songs. A distinctive characteristic of Queen's music are the vocal harmonies which are usually composed of the voices of May, Mercury, and Taylor best heard on the studio albums A Night at the Opera and A Day at the Races. Some of the ground work for the development of this sound can be attributed to their former producer Roy Thomas Baker, and their engineer Mike Stone. Besides vocal harmonies, Queen were also known for multi-tracking voices to imitate the sound of a large choir through overdubs. For instance, according to Brian May, there are over 180 vocal overdubs in "Bohemian Rhapsody". The band's vocal structures have been compared with the Beach Boys, but May stated they were not "much of an influence".

What engineer helped with Queen's feedback heavy sound?
