[a] Define the term output device.
[b] Give the two types of printers.
[c] [i] Construct a truth table for an AND gate with two input signals.
[ii] State the output of an OR gate with the signals 0 and 1.
[d] list two types of an logic gate that gives an output of 1 when all of its input signals are 1.
Explanation
[a] An output device is any piece of computer hardware equipment or peripheral that converts information into a human-perceptible form or machine-readable form for use with other non-computerized equipment. It can be text, graphics, audio, or video. This piece of equipment hardware which gives us the result of the entered input, once it is processed.
[b] Two types of printers are: (i) Impact Printer and (ii)Non Impact printer
[c] i A truth table for an AND gate with two input signals
| Inputs | output | |

| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
[c] iii The output of an OR gate with the input signals 0 and 1 is 1.
[d] 1: AND gate
2: OR gate
