Here is a question about this article: A group of seven companies began the development of USB in 1994: Compaq, DEC, IBM, Intel, Microsoft, NEC, and Nortel. The goal was to make it fundamentally easier to connect external devices to PCs by replacing the multitude of connectors at the back of PCs, addressing the usability issues of existing interfaces, and simplifying software configuration of all devices connected to USB, as well as permitting greater data rates for external devices. A team including Ajay Bhatt worked on the standard at Intel; the first integrated circuits supporting USB were produced by Intel in 1995.
What is the answer to this question: What was the goal for USB's?

So... to make it fundamentally easier to connect external devices to PCs

Here is a question about this article: Sanskrit has also influenced Sino-Tibetan languages through the spread of Buddhist texts in translation. Buddhism was spread to China by Mahayana missionaries sent by Ashoka, mostly through translations of Buddhist Hybrid Sanskrit. Many terms were transliterated directly and added to the Chinese vocabulary. Chinese words like chana (Devanagari: ksana 'instantaneous period') were borrowed from Sanskrit. Many Sanskrit texts survive only in Tibetan collections of commentaries to the Buddhist teachings, the Tengyur.
What is the answer to this question: Where do many Sanskrit texts survive?
