Quite a few words from the variety of Old Chinese spoken in the state of Wu (where the ancestral language of Min and Wu dialect families originated and which was likely influenced by the Chinese spoken in the state of Chu which itself was not founded by Chinese speakers),[citation needed] and later words from Middle Chinese as well, have retained the original meanings in Hokkien, while many of their counterparts in Mandarin Chinese have either fallen out of daily use, have been substituted with other words (some of which are borrowed from other languages while others are new developments), or have developed newer meanings. The same may be said of Hokkien as well, since some lexical meaning evolved in step with Mandarin while others are wholly innovative developments.

Where did the language of Min and Wu dialects originate?
Answer: in the state of Wu

The core technology used in a videoconferencing system is digital compression of audio and video streams in real time. The hardware or software that performs compression is called a codec (coder/decoder). Compression rates of up to 1:500 can be achieved. The resulting digital stream of 1s and 0s is subdivided into labeled packets, which are then transmitted through a digital network of some kind (usually ISDN or IP). The use of audio modems in the transmission line allow for the use of POTS, or the Plain Old Telephone System, in some low-speed applications, such as videotelephony, because they convert the digital pulses to/from analog waves in the audio spectrum range.

What is one digital network through which a digital stream can be transmitted?
Answer: IP

In the first half of the 20th century, advances in electronics enabled investigation of the electrical properties of nerve cells, culminating in work by Alan Hodgkin, Andrew Huxley, and others on the biophysics of the action potential, and the work of Bernard Katz and others on the electrochemistry of the synapse. These studies complemented the anatomical picture with a conception of the brain as a dynamic entity. Reflecting the new understanding, in 1942 Charles Sherrington visualized the workings of the brain waking from sleep:

Work in the first half the 20th century in electrical properties of nerve cells were by what two main scientists?
Answer:
Alan Hodgkin, Andrew Huxley
