Operation

How many pins does a parallelport have?

• 9

• 15

• 25

• 30

Which pins are used for output(data pins)?

• 1 to 8

• 2 to 9

• 10, 11, 12, 13, 15

• 18 to 25

Pins 10 and 11 of a parallelport are used for?

• input

• output

• ground

• for any function

The solid green wire from Pin25 of our cable is used for:

• input

• output

• ground

• none of the above

The command to send current out through the 3 pin (D1) which is the second output pin with a white/blue wire is:

• parallelput(1)

• parallelput(2)

• parallelget(2)

• parallelget(4)

To send current to the first 4 output pins, the value of the parallelput command would be:

• 8

• 15

• 31

• 128

Which statement is NOT true about LEDs?

• Current can flow in both directins

• The anode leg is the positive leg

• The positive leg is usually longer

• LEDs light up when current flows through them

The value of this resistor is:

• 1000 ohms +/- 5%

• 31K ohms +/- 5%

• 10K ohms +/-5%

• 220 ohms +/-10%
