The Arabic term ijazat al-tadris was awarded to Islamic scholars who were qualified to teach. According to Makdisi, the Latin title licentia docendi 'licence to teach' in the European university may have been a translation of the Arabic, but the underlying concept was very different.

What type of license is closely related to the ijazat al-tadris?
****
The answer: licentia docendi

Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space. Computers are small enough to fit into mobile devices, and mobile computers can be powered by small batteries. Personal computers in their various forms are icons of the Information Age and are generally considered as "computers". However, the embedded computers found in many devices from MP3 players to fighter aircraft and from electronic toys to industrial robots are the most numerous.
How much more powerful are modern computers versus early computers?
****
The answer: millions to billions of times

In addition to strictness in character size and shape, Chinese characters are written with very precise rules. The most important rules regard the strokes employed, stroke placement, and stroke order. Just as each region that uses Chinese characters has standardized character forms, each also has standardized stroke orders, with each standard being different. Most characters can be written with just one correct stroke order, though some words also have many valid stroke orders, which may occasionally result in different stroke counts. Some characters are also written with different stroke orders due to character simplification.
What are written with very precise rules?
****
The answer:
Chinese characters
