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.

Ah, so.. unanswerable

A web browser (commonly referred to as a browser) is a software application for retrieving, presenting, and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI/URL) and may be a web page, image, video or other piece of content. Hyperlinks present in resources enable users easily to navigate their browsers to related resources.

Ann Arbor has a long history of openness to marijuana, given Ann Arbor's decriminalization of cannabis, the large number of medical marijuana dispensaries in the city (one dispensary, called People's Co-op, was directly across the street from Michigan Stadium until zoning forced it to move one mile to the west), the large number of pro-marijuana residents, and the annual Hash Bash: an event that is held on the first Saturday of April. Until (at least) the successful passage of Michigan's medical marijuana law, the event had arguably strayed from its initial intent, although for years, a number of attendees have received serious legal responses due to marijuana use on University of Michigan property, which does not fall under the City's progressive and compassionate ticketing program.

Ah, so..
