Network of Local Area (Local Area Network) The Network
of Access is used, as his name says it, to have access
towards a
network of widespread area.
This type of network when it does not possess connection
with other cities, because it is not connected to a
network of widespread area, calls him Internal Network
(Intranet).
It is a system of communication between computers, which
allows to share information and resources, with the
characteristic of which the distance between the computers
must be small.
The topology or the form of connection of the network,
depends on some aspects like the distance between the
computers and means of communication among them since
this it determines, the speed of the system.
There are three topologies of network:
•It
stars (Star)
•Channel
(Bus)
•Ring
(Ring)
A network must be:
• |
Reliable. To be available when it
is required to him, to have speed of suitable answer.
|
• |
Confidential. To protect the data
on the users of thieves of information.
Integra. In its handling of information. |
• |
The three mentioned types of connection
are the main ones to communicate a series of computers
of the same family. |
The Network operating
system NET BIOS (NETwork Basic Input/Ouput System),
allows to control all the devices of the network, from
archives to periphery.
Operating with archives:
This Operating system allows to block registries of
archives (record Lock) with the purpose of assuring
that the registry access by a user is not modified by
another one, allowing ace that the rest of the ready
file rest to be used. Once defined the form of installation
of the network, it is possible to form each one of the
workstations of 4 different forms, depending on configuration,
the computer could send or to receive messages and to
use or to share peripheries
