Hi
My friend told me the switch will not assign IPs to clients but
router will. Is he correct?

Neither switches nor routers assign IP addresses. If you are in dhcp
mode, the dhcp server assigns the addresses. If you are in manual
mode the user assigns the IP address through some software program.

In the "old days" all these devices you are talking about were separate
boxes. Now one box many different functions - thus confusion.

What is the different between switch and router?

A switch connects 2 or more computers and makes connections
so that all the computers do not get a broadcast, only the two computers
communicating (as opposed to hub). In a hub everyone shouts so everyone
hears, in a switch only the two computers communicating get the broadcast.
Look up virtual lans and virtual circuts.

so far i know, you
can link two linksys switch to get 200% speed

The slang for getting 200% speed really means that the data is traveling
both ways at the same time. In a 100 baseT network, the connection
means that the data is traveling at 100MB/s in one way. If the data is
traveling both directions at the same time, it is like getting 200MB/s of
effective rate, or 200% speed. You don't need to connect 2 switches
together to get this phenomenon.

later.....

Hi, as you said, switch connect 2 computers, but the switch doesn't
assigne IPs for them, so how can the switch do it?
"hub everyone shouts so everyone hears, in a switch only the two
computers communicating get the broadcast." <------ OK, that mean
the switch is much for faster then hub. Except the matter of speed, it
there any thing else the switch can do but the hub/router don't?
thank you everybody

Depends on what the engineers designed into the thing. If you go
out and get a high end Cisco switch you may be able to use fiber
connections, assign/configure multiple virtual lans, have active
SNMP monitoring and have lots of ports. On the other hand, if you
go out and get a $40 switch from Fry's, you will be able to say that
the connections are not the type used in a hub and you may get
4 ports with no cascading and all plastic parts and a waurantee
that says it will work until you hit the front door.
