Can you run 100 Kb and 1000 Kb on the same network?

[Graham Brooker]

I need to replace a faulty 10/100 Kb switch. Everything runs at 100 Kb at
present but I have a 1000 Kb NAS and any future new PC will be 1000 Kb
compatible. My network has 3 x 100 Kb switches at present and one needs
replacing now.

Is there any benefit if I buy a new 1000 Kb switch, which presumably will
work better than the older style anyway. If any of the routes are 1000 Kb
at each end is it possible to have both speeds running on the same network
or will I only see a benefit if I change all the network adapters to faster
speed.

Thanks

Graham

Switches have "dedicated" speeds per port. The only benefit will be
that your 1000 Kb (aka Gigabit) device will communicate faster.

A good compromise is a switch with two GHz ports. This will allow you to
link the 'backbone' of the LAN at a higher speed, but is a lot cheaper than
an all-GHz switch. Since this provides you with a 'diversity' of ten users
accessing the NAS or linking between departments at once, it avoids
bottlenecks.

Netgear FS726T is an example of such.

Hi
Giga switch is Dual speed and its ports are MDX (I.e no need for Uplink or
Crossover cables).
Just buy a good Giga switch and use it. (example,
http://www.newegg.com/Product/Product.aspx?Item=N82E16833156251 ).
All the other concoctions are stuff from the infancy days of Giga and there
is No reason to get them these days.
