An inverting amplifier is a type of operational amplifier (op-amp) circuit that amplifies the input signal and produces an output with a phase reversal. In this configuration, the input is connected to the inverting input (-) through a feedback resistor (Rf), and the non-inverting input (+) is usually grounded. The gain of the inverting amplifier can be calculated as -Rf/Ri, where Ri is the resistance between the input and ground.

.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
