Hello
We have a big building, we cannot connect all of them to one switch so we need to use multiple switches on different locations, Switch A is main Switch B,C are sub Switches is their any rule to connect from A to B or C we should connect to the last port of sub Switches?

Switches just repeat the signal to all ports so it does not matter which port you plug into since all of the ports will get the signal sent through them and only the system that it is addressed to in the packet will recieve it - the rest will just ignore it since it is not addressed to them.

What JDFan said. Assuming your subnet mask is setup correctly, all computers should be able to talk to eachother.

Although, if you have a lot of devices plugged in, I would get at least one layer3 managed switch(aka router) and break up your broadcast domain.

JDFan, Switches DO NOT repeat signals to all ports. That is a hub.
A switch will only send the packet to appropriate port or ports if multicast.
Pretty much all the business class switches will have auto-mdx on the ports so you can just plug into what ever port you want.
I would use switches that have fiber uplink ports for speed and reliability.

Sturm ! you took JDfan wrong JDfane explained technically which means that signal get weak due to noise or long travelling through the cable, when it reaches to the switch- the switch will repeat(amplify) the original signal but not the noise, and you are right in second line-- "the switch send the amplified signal to the concerned port only".

The gigabit spec calls for auto MDI-X so gigbit switches should not need crossover cables. Older 10/100 switches may have an uplink port or you can use a crossover cable on a normal port.

If the switch has auto mdi-x ports, then no need to worry about crossover cables.

A lot of the configuration depends on your switches. But typically you connect one switch to another from whatever port you want. Gigabit devices support auto MDI-X. . In my small / medium business installations using broadband connections it has been...

NOTE: Each "|-" represents one level down. For example, devices following |-|- are connected to the device marked |- and so on.
NOTE 2: Depending on the application, WiFi Access point, Firewall, Proxy server, Security network etc... CAN exist as a single broadband / WiFi router. It is demanding a LOT of a router, but for example an Asus RT-N66u, or Buffalo WZR-600dhp with DD-WRT, either are up to the task for lower requirement networks.

ISP modem , network adapter, whatever your ISP calls what they use to connect your net to theirs...(Cable, DSL, FiOS, Google Fiber, whatever...)

|- Business class firewall router. Make and model varies by need and budget of client.
|- Security network, proxy servers etc..
|-|
|-|-WiFi access point. Again make / model varies. Can be SOHO class router with DD-WRT in access point mode.
|-|-Big Switch A. Servers. If space allows, workstations requiring fastest access to servers.
|-|-|-Big Switch B. Workstations requiring fast, but not fastest network access.
|-|-|-|-Big Switch C. Workstations, printers, and appliances having least requirement for bandwidth.

For the most part, crossover cables are a thing of the past. There are still a lot of old 10/100 switches out there that would need them, but gigabit has no need.
