    Nana and Nathan will pop round, but don& #39;t worry, it& #39;s gonna be lols . So take a look at that Verizon message again: Did you second guess the number it came from? In the hacking world, this is called "spoofing." By spoofing a customer into thinking they are communicating with a trusted business, the hacker can trick you into handing over your login user names and passwords.

    During this time, there was also research into other forms of digital video and audio communication.Many of these technologies, such as the Media space, are not as widely used today as videoconferencing but were still an important area of research.This was first embodied in the device which came to be known as the video telephone, or videophone, and it evolved from intensive research and experimentation in several telecommunication fields, notably electrical telegraphy, telephony, radio, and television.Simple analog videophone communication could be established as early as the invention of the television.In 1995 the first public videoconference between North America and Africa took place, linking a technofair in San Francisco with a techno-rave and cyberdeli in Cape Town.At the Winter Olympics opening ceremony in Nagano, Japan, Seiji Ozawa conducted the Ode to Joy from Beethoven's Ninth Symphony simultaneously across five continents in near-real time.Finally, in the 1990s, Internet Protocol-based videoconferencing became possible, and more efficient video compression technologies were developed, permitting desktop, or personal computer (PC)-based videoconferencing.

    Very expensive videoconferencing systems rapidly evolved throughout the 1980s and 1990s from proprietary equipment, software and network requirements to standards-based technologies that were available for anyone to purchase at a reasonable cost.Only in the late 20th century with the advent of powerful video codecs combined with high-speed Internet broadband and ISDN service did videotelephony become a practical technology for regular use.In the 1980s, digital telephony transmission networks became possible, such as with ISDN networks, assuring a minimum bit rate (usually 128 kilobits/s) for compressed video and audio transmission.During the first manned space flights, NASA used two radio-frequency (UHF or VHF) video links, one in each direction.TV channels routinely use this type of videotelephony when reporting from distant locations.
