Explanation: When the button is pressed,the contact surfaces bounce and hence it might lead to generation of multiple signals.In order to overcome this we use Debouncing circuits. 3. The best mode of conncetion between devices which need to send or recieve large amounts of data over a short distance is _____ .
A. BUS
B. Serial port
C. Parallel port
D. Isochronous port
Answer:A
Explanation: When the button is pressed,the contact surfaces bounce and hence it might lead to generation of multiple signals.In order to overcome this we use Debouncing circuits. 3. The best mode of conncetion between devices which need to send or recieve large amounts of data over a short distance is _____ .
A. BUS B. Serial port C. Parallel port D. Isochronous port
Explanation: The parallel port transfers around 8 to 16 bits of data simultaneously over the lines, hence increasing transfer rates.
