Verizon Wireless traces its roots to Bell Atlantic Mobile, NYNEX Mobile Communications, Air Touch Communications, Prime Co Communications, and GTE Mobil net. Bell Atlantic Mobile and NYNEX Mobile Communications merged in 1995 to create Bell Atlantic - NYNEX Mobile,[6] and in 1997 their namesake Baby Bell parents followed suit to form the new Bell Atlantic and their wireless

subsidiary was renamed Bell Atlantic Mobile. Bell Atlantic Mobile and NYNEX Mobile Communications were created from Advanced Mobile Phone

Service, Inc., which was a

subsidiary of AT&T created in 1978 to provide cellular service nationwide. AMPS, Inc. was divided among the RBOCs as part of the Bell System Divestiture.

The Internet is a global system

of interconnected computer

networks that use the standard

Internet Protocol Suite (TCP/IP)

to serve billions of users

worldwide. It is a network of

networks that consists of

millions of private, public,

academic, business, and

government networks, of local

to global scope, that are linked

by a broad array of electronic,

wireless and optical

networking technologies. The

Internet carries a vast range of

information resources and

services, such as the inter-

linked hypertext documents of

the World Wide Web and the

infrastructure to support

electronic mail. An Internet service

provider (ISP) is a company that

provides access to the Internet.

Access ISPs connect

customers to the Internet using

copper, wireless or fiber

connections. Hosting ISPs

lease server space for smaller

businesses and host other

people servers’ collocation

Transit ISPs provide large

tubes for connecting.

A communications satellite

(sometimes abbreviated to

COMSAT) is an artificial satellite

stationed in space for the

purpose of telecommunications.

Modern communications

satellites use a variety of orbits

including geostationary orbits,

Molina orbits, other elliptical

orbits and low (polar and non-

polar) Earth orbits. For fixed

(point-to-point) services,

communications satellites

provide a microwave radio relay

technology complementary to

that of submarine

communication cables. They are

also used for mobile applications

such as communications to

ships, vehicles, planes and hand-

held terminals, and for TV and

radio broadcasting, for which

application of other

technologies, such as cable, is

impractical or impossible.

Telecommunication

s and meteorology

Meteorology is the science that

studies atmospheric phenomena,

especially those that relate to

weather. Meteorologists who

forecast the weather rely on

thousands of weather stations

located around the world, both on

land and at sea. At each station,

measurements are taken of such

things as air pressure and

temperature, wind speed, cloud

cover, and precipitation. Elsewhere,

upper-level observations are made by

weather balloons, and satellites,

which send a continuous flow of

photographs back to earth. All of this

information is sent to national

weather centers where it is plotted

on charts and analyzed by

meteorologists. This information,

called a forecast, is then sent to the

public by newspapers, radio and

television. Meteorology is important

because we are learning about our

atmosphere, the weather, and the

things that shape our world. It helps

us learn more about how to predict

natural disasters and prevent more

destruction....meteorology is very

helpful and a great part of

science...and also a super fun field to

work in.
