Answer Details

a. An output device is a hardware component of a computer system that displays or prints the results or output of a computer's processing or data manipulation. b. The two types of printers are: - Impact printers: These printers produce printed characters or images by striking an inked ribbon against paper. Examples include dot-matrix printers. - Non-impact printers: These printers produce printed characters or images without striking the paper. Examples include inkjet printers and laser printers. c. i. A truth table for an AND gate with two input signals is as follows: | Input 1 | Input 2 | Output | |---------|---------|--------| | 0 | 0 | 0 | | 0 | 1 | 0 | | 1 | 0 | 0 | | 1 | 1 | 1 | ii. The output of an OR gate with the signals 0 and 1 is 1. An OR gate produces a logic 1 output when either or both of its input signals are 1. d. Two types of logic gates that give an output of 1 when all of its input signals are 1 are: - AND gate: An AND gate produces a logic 1 output only when all of its input signals are 1. - NAND gate: A NAND gate is the opposite of an AND gate, and produces a logic 0 output only when all of its input signals are 1. However, by adding an inverter to the output of an AND gate, a NAND gate can be created.
