The first indication of communication networks was telephonic and telegraphic
technology. In 1940 data weretransmitted from Dartmouth University, New
Hampshire, New York. In the late 1960s and in the subsequent 70 were created
minicomputers. In 1976, Apple introduced the Apple I, an early personalcomputers. In 1981, IBM introduced its first PC. Midway through the 1980 start
using the PC modems to share files with other computers in a range of speeds
that began in 1200 and reached bps to 56 kbps(point-to-point or dial-up), when
they started to be replaced by higher-speed system, especially ADSL.
What we intend to computer networks?
Well have the ability to capture, store, process, retrieveand transmit information
between people or between people and computers, or between computers and
computers. Now when we talk about computer networks first lines that connect
remote places, but toget benefit from increased transmission capacity of
existing lines and networks and, a fortiori, in the future, we will surround these
physical elements of a number of protocols and services thatfacilitate access of
people to information.
There are different types of networks, among which are the scope of which are
derived:
-Personal area network PAN is a computer network used forcommunication
between the computer devices.
-Local Area Network or LAN is a network that is limited to a relatively small
special area such as a room, a single building, a ship or an aircraft.
-MetropolitanArea Network or MAN is a high-speed network that covers a
geographic area larger than a campus, but still limited.
The most known and used worldwide network of networks is the "Internet",
whichlets you connect to different users around the world.Internet technology
is a precursor of the so-called information superhighway, a theoretical goal of
computer communications that would provide...
