In the previous lecture, we had a problem when we were trying to access resources from different network
segments where there is a typical network issue that's easily resolved by using a cool device called
a router, as you can see in the middle of the diagram.
Nice, then problem solved.
Well, even though you can use it outdoors for more than just connecting the lens, rorter shown in
the figure is a great solution because the host computers from the fields land can now get to the resources
of the marketing man and vice versa.
Now, you might be thinking that we really don't need a router that could just physically connect the
two workgroups with a type of cable that would allow the marketing and the sales work groups to hook
up somehow.
Well, there is also a solution.
We could do that, but if it did, we would have only one big cumbersome workgroup group instead of
separating work groups for marketing and sales.
And that kind of arrangement just isn't practical for today's networks.
This is because with smaller individual yet connected groups, the users on each LAN enjoy a much faster
response times when accessing the resources and administrative tasks are a lot easier.
Also now, larger war groups run more slowly because there's a legion of hosts within them and all are
trying to get the same resources simultaneously.
So the router shown in the figure which separates the work groups while still allowing the access between
them, is really a great solution.
Well, I would like to again tell you that do not focus too much on the network connectivity devices
like the hubs, routers and switches I've mentioned so far in this section yet that these devices we
will be all covering in the sections of networking devices right now.
I really want you to prioritize your understanding of the concepts that I am presenting here.
So at this point, all you need to know is that hubs and switches are devices that connect other devices
together into a network, and routers connect to different network segments together.
OK, so in the next lecture, I will define the other terms that I have used so far, that is workstations,
servers and hosts.
