Five computing terms are described below. Write the name of the term being described. Software that anyone can download for free from the Internet and then use without having to pay any fees. The usual copyright laws apply and a user license is important. Software that gives the user the chance to try it out free of charge before actually buying it. The software is subject to the usual copyright laws. As a rule, not all the features found in the full version are available at this stage. Software where users have freedom to run, copy, change and adapt it. This is an issue of liberty and not of price since the software guarantees freedom and the right to study and modify the software by having access to the actual source code. Set of principles that regulates the use of computers in everyday life. This covers intellectual property rights, privacy issues and the effects of computers on society in general. The taking of somebody’s idea or software and claim that the idea or software code were created by the “taker”.

Leonard has a new laser printer to print letters for his business. Leonard connects his printer to his computer using the USB port. Give three benefits of using the USB port to connect the printer to the computer. Benefit 1 Benefit 2 Benefit 3 State two benefits and one drawback of Leonard using a laser printer, instead of an inkjet printer, to print the letters. Benefit 1 Benefit 2 Drawback An interrupt signal is sent from the printer to the computer. Give two examples of when a printer would generate an interrupt signal. Example 1 Example 2 Many devices send interrupt signals. Identify the software in the computer that will receive and manage all interrupt signals.
