A keyboard connected to a computer is used at a rate of 1 keystroke per second. The computer polls the keyboard every 10 ms, each poll takes 100 \(\mu s\). If a key is detected, an additional 200 \(\mu s\) is used for processing. Let \(T_1\) be the fraction of a second spent in polling and processing a keystroke. In an alternative implementation with interrupts, each keystroke requires 1 ms to service and process. Let \(T_2\) be the fraction of a second in the interrupt method. Find the ratio \(T_1/T_2\).
