Hubs
 The
fundamental difference between a hub and a switch is that
all Computers and / or peripherals (nodes) connected to a
hub share the bandwidth among themselves while Computers and
/ or peripherals (nodes) connected to a switch port have the
full bandwidth all to themselves.
The Hubs provide an easy
way to scale up and shorten the distance that the packets
have to travel to get from one node to another but they do
not break up the actual network into discrete segments. That
is where switches come in.
Switches
 A
typical network consists of computers (nodes), a connectivity
spectrum of wired or wireless solutions and specialized network
equipment like switches and routers. All these pieces working
together allow your computer to send information to another
computer.
Switches
are a fundamental part of most networks by allowing several
users to send information over a network at the same time
without slowing each other down. Switches allow different
computers of peripherals (nodes) of a network to communicate
directly with each other in a smooth and efficient manner.
Today's switches have the potential to radically change the
way the computers and /or peripherals (nodes)
can communicate with each other. Many companies have grown
in size and complexity over time and their networks will grow
with them. One of new challenging networking solution for
us is to provide: more network security and more bandwidth
to our customers. That is why we turned to Virtual Local Area
Networks (VLANs) for all solutions we provide to our customers.
A VLAN is a collection of Computers and / or peripherals (nodes)
that are grouped together in a single broadcast domain
 VLANs
(Virtual Local Area Networks)
Give us the possibility to provide solutions which will have
multiple broadcast domains over the network and will increase
security & bandwidth for our customers. The VLANs can
communicate with each other using the router.A LAN is a collection
of Computers and / or peripherals (nodes) that are grouped
together in a single broadcast domain.
A broadcast domain is a network
(or portion of a network) that will receive broadcast packet
or packets from any other node located within that network.
A switch that was configured for VLANs has
multiple broadcast domains; but, you still need a router to
route packets of information's from one VLAN
to another; the switches can't do this by themselves.
In today's market SANTEC
Communications challenge is to  provide
reliable and scalable Networking Solutions to our customers.
We understand that our customers will have to rely more and
more on Internet Broadcasting in order to be able to reach
people anywhere in the world with voice, data and video applications.
This broad new spectrum of platforms and applications will
make content delivery via the Internet a challenging proposition
for us. |
