elecommunications and Its History
where did the word telecommu
nications come from?
from Old.French. communicacion, from Latin. communicationem (nom. communicatio), from communicare "to share, divide out; impart,
inform; join, unite, participate in," lit. "to make common," from communis
what does that term mean?
impart, inform; join, unite, participate in," lit. "to make
common," from communis
what are some basic elements in the telecommunications?
a transmitter that takes information and converts it to a signal;
a transmission medium that carries the signal; and,
a receiver that receives the signal
and converts it back into usable information.
nternet Knowledge What is the internet?
is a global system of interconnec
ted computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide.
What services does it provide?
The World Wide Web
Remote access
Collaboration
File sharing
Streaming media
Internet Telephony (VoIP)
Videos
Information
Web pages
gaming
microsoft
What is web 2.0?
is associated with web applications that facilitate
participatory information sharing, interoperability, user-centered design,[1] and collaboration on the World Wide Web

what is a satellite?
is an object that goes around, or
orbits, a larger object, such as a planet. While there are natural satellites, like the Moon, hundreds of man-made satellites also orbit the Earth.
What services or uses does a
satellite provide ?
The service can be provided to users world-wide through Low Earth Orbit (LEO) satellites.
Geostationary satellites can offer higher data speeds, but their signals can not reach some polar regions of the world. Different types of satellite systems have a wide range of different
features and technical limitations, which can greatly affect their usefulness and
performance in specific applications.
What is an orbit?
An orbit is a regular, repeating path that an object in space takes around another one.
What is a communications satellite?
Since 1972, the world has employed communication satellites to revolutionize the way humans connect with each other.
can you gice me a example of communication satellites?
Miami's top choice for Satellite Uplink and Downlink Services.
What elements from a satellite communication system?
In general, a satellite is anything that orbits something
else, as, for example, the moon orbits the earth. In a
communications context, a satellite is a specialized
wirelessreceiv
er/transmitter that is launched by a rocket and placed inorbit around the earth. There are hundreds of satellitescurrently in operation
elecommunications and meteorology.
What is meteorology?
Meteorology is the
science that studies atmopheric phenomena, especially those that relate to weather.
What is the importance of meteorology?
Meteorology is important because we are
leanring about our atmosphere, the weather, and the things that shape our world.
How are telecommunications and satellites useful for meteorology?
Satellite-based data collection and distribution systems are integrated in the GTS as an essential element of the global, regional and national levels of the GTS
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, Molniya orbits, other elliptical orbits and low (polar
and non-polar) Earth orbits.
What are weather maps?
A weather map displays various meteorological features across a particular area at a particular point
in time.Such maps have been in use since the mid-19th century and are used for research and weather forecasting purposes. Maps using isotherms show temperature
gradients,which can help locate weather fronts.
Do you know of any event of the history of your country in which meteorology aided by telecommunications and satellites
useful for meteorology?
A Weather forecasting is the application of science and technology to predict the state of the atmosphere for a given location. Human beings have
attempted to predict the weather informally for millennia, and formally since the nineteenth century. Weather forecasts are made by collecting quantitative data
about the current state of the atmosphere and using scientific understanding of atmospheric processes to project how the atmosphere will evolve.
Were you directly affected by that situation?
In my house, family,and also of been a human been.
