for an example
In our office only 400 systems are available. We cannot buy a Cisco switches because of more cost.
So we've to buy a net gear or sys link switches. So how many ports of switches need.
Really I can't to understand...
next kindly please how to connect from broadband connection(//)
you need 1 port for each connection, so 400 + 1 for broadband
There also needs to be a switch port available for connecting to another switch. Two ports if you want to have high availability for your distribution switches - which I do recommend so that you don't have all your access switches cascading off of each other.
Hmm! It's okay if I have 48 port Cisco switch. How many systems able to connect to the switch

48
Well, that's 48 endpoints if you're not linking the switch to anything else.
And to the OP, you really do not want to have a chain of switches in serial. You will likely want to have access switches for your endpoints, and then those access switches would connect to a distribution switch that will handle communication between the switches.
For 400 devices, are you planning on zero redundancy?
You could do 400 devices with off the shelf switches. Take a 24-port gigabit switch. Subtract one for your internet gateway, and you'd have 23 available ports for devices. Connect each of these to another 24-port gigabit switch, and you'd have 23-ports on each of those available. I'll let you do the math from there.
And I'd fire any engineer who thought that was a good design.
