Question

With 1MB internet connection, how many PCs on my LAN i can brwse net with same speed of 1MB.is there any limit

Answer 1

Bandwidth gets shared through all computers, if there where two computers, it would be 50/50. More bandwidth usually tends to go with the user that is actually using the internet if someone is surfing the web and the other is afk its going to be 90/10%

Answer 2

This is a factor of Contention Ratio.  Your LANs contention ratio is x:1 to your point-to-internet gateway (router), where x = number of PC's and network devices (xbox, PS etc etc) that require access to the internet .  Contention Ratio is a network fact of life, and also effects your internet connection.  If you have a standard residential grade connection, your ratio will be in the range of 25:1 -> 80:1.  That is to say, your 1 Mbps link*, is probably at best, only 1 in 25 other links that are vying for 1 Mbps of bandwidth.  (You don't say if your link is symmetric [ie. upstream matches downstream 1000/1000 Kbps] or asymmetric [1000/256 or 128 Kbps, for example. There are many different asymetric configurations]. This could be very important if you have 512 Kbps or less upstream and want to be able to run voice/video sessions).

As to the extent of the effect that contention ratios may have, this also depends on the nature of the 'services' you are using.  Real-time services such as the voice streams for VoIP, and some online gaming streams are very sensitive to network latency - and high contention ratios can further degrade your abillity to satisfactorily use them, during peak load times in particular.  Other common services such as email do not require real time, thus, transfer of this data can be forced to wait a little, to ensure real time data passes with as little delay as possible.  This is what Quality of Service (QOS) is all about.  All major network providers implement QOS over their networks in order to squeeze the maximum amount of headroom from them.  You can do the same on your home network by obtaining control devices such as switches and routers that are QOS enabled.

Some usage is not real time dependant, but because of the scale of usage, it can have a detrimental effect on other network users.  For instance, if one of your PCs was constantly downloading or uploading large files, then, depending on the protocol being used, that could seriously distort and congest your network for other users.  QoS combined with protocol Throttling is generally the solution for that instance - particularly if you are running voice services.

In short, to fully answer your question, you need first to understand the contention ratio of your internet link - then being mindful of the type of usage you require for the PC's on your LAN you can assess if your link needs upgrading or supplementing, (sometimes two links are better than one).

PS.> I found some easy to digest entries on wikipedia that may assist you to understand this better.

*I presume you mean your link is 1 Mega Bit Per Second typically written as 1Mbps not 1MB which signifies Mega Bytes. [http://en.wikipedia.org/wiki/Mega_bit]

Answer 3

yeah! there's a limit for example.. in your LAN there are 5 computers.. one is downloading a movie.. and it consumes all the bandwidth of your PC.. which makes it 1mb...

if the 2nd computer downloads too.. it will surely eat the connection of the 1st computer that will somewhat divide the bandwidth.. so to make it short.. your 1mb connection..  could become 200kbps only for each computers .. if that 5 computers connected on your LAN .. is downloading in it's full speed.. at the same time

okiez! cheers!

Usually if your connecting through a router the router will boost your connect slightly or even maybe a lot.
