see we can t get the bandwidth of any amplifier u cn figure
it out wen u see a graph.so they (one who decided to use
half power point)to find the cut off freq because we need to
know about bandwidth for using it so cut off freq are needed
this cut off freq are get at 3 db point only.
y 3 db point?
is the q rite because we humans having percistence for
everything even for hearing and all we can able to sense the
change only wen the power gets at half power point . so it s
a got thearitically and kept for use 3 db point we can get
band width of amplifiers etc

What are the test parameters to check the proper functionlity of TCP/IP protocol.
.We want to compare the performance of a single threaded disk server with a multithreaded 1. Suppose the server takes 25 ms to receive a request for work from client, dispatch the request for processing and actual data request processing when reqd. Data is in main memory. If the reqd. Data is not in the main memory a real disk operation is needed and an additional 75 ms are reqd. On the average. On the average 25% of the clients requests access the disk. During the disk I/O period the thread waits. Assume that there is no other process in system when the server is running. How many requests can the server handle per second if its a)single threaded b)multithreaded
