Question.
User(s) are complaining of delays when using
the network. What would you do?
Ans.
Network slow problem create by many reasions like.. Spyware, Virus, Spool Virus, NetBios, or may be any machine infected with a Virus or Worm..
the above is solutin may be coreect but another cause to daely is that if there is nay cycle b/w n/w then user called the dealy
for this at present we switch off and then on the switch so that cycle and break and afte that we serach the reason of loop and then we will solve the problem
virous and strom efeect on;y your system pefrommance not the n/w performance
(1)the main problem working on switched lan is loop/cycle formation which cause the delay,
(2)another problem is that as switch is a single broad cast doman so it condume the more resoses at the time
tcp/ip nd its role-
tcp/ip is a set of rules and known as transmission control protocall/internet protocall.
it is conection less protocall and farme of data can tarvel with in any path of given n/w
in the tcp it wait for ack after delevering each farme.
tcp/ip is reponsble for
(1)error corection
Handshaking.
2. Packect Sequencing
3. Flow Control.
4. Error handling
udp-
udp is a constion orented protocall and know as user data garm protocall
in the udp data is tarvled on a specfic path
and get ack after delevring the all data t the destination,
it is also known as thin protoall and doesnot consume much bandwith
udp is applied when there is no reqirment of relable data delevery
