All about networks
The computing network:

2. A computer network is a set of devices interconnected among
themwho through a medium, exchange information and share
resources. Basically, communication within a computer network is a
process in which there are two well-defined roles for connected
devices, transmitter and receiver, which are assuming and alternating
in different moments of time. Networking is simply the joining of data
from two or more computers through a transmission medium.
Classification:
LAN: structuring of networks whose components are in
relatively short distance and because of its proximity are
permitted to use a coaxial cable.
WLAN: is a network that uses wireless LAN media. It is widely
used for its scalability because it requires no configuration and
installation of cables.
CAN: is a network of high-speed devices connecting LANs via
a limited geographical area, such as a university campus, a
military base, etc. Do not use public transport.
VLAN: It is a type of logical or virtual LAN, mounted on a
physical network, in order to increase safety and performance.
In special cases, thanks to 802.11Q protocol (also called
QinQ).
Typesofnetworks
Shared networks: They are a large number of users join,
sharing all transmission needs.

3. Multipoint networks: It allows the union of several terms
to its corresponding computer sharing a single transmission
line.
Packet communication networks: They are networks in
which nodes are processors that regulate concentration
packet traffic.
Digital networks: technological developments are based
on digital transmission and switching and is a digital network
testament use of services ranges.
Public networks: They are those belonging to state bodies
and are open to anyone who asks for them the corresponding
contact.
Large enterprise network: expands the network of
companies and releases the traffic problems in networks.
