The operating system (OS) contains code for performing various management tasks. The appropriate code is run when the user performs various actions. Draw a line to link each OS management task to the appropriate user action. Main memory management Input/Output management Secondary storage management Human computer interface management The user moves the mouse on the desktop The user closes the spreadsheet program The user selects the Save command to save their spreadsheet file The user selects the Print command to output their spreadsheet document OS management task Action A user has the following issues with the use of his PC. State the utility software which should provide a solution. The hard disk stores a large number of video files. The computer frequently runs out of storage space. Utility software solution The user is unable to find an important document. He thinks it was deleted in error some weeks ago. This must not happen again. Utility software solution The operating system reports ‘Bad sector’ errors. Utility software solution There have been some unexplained images and advertisements appearing on the screen. The user suspects it is malware. Utility software solution

Kimmy has written a program in a high-level language. Kimmy has used library routines in the program. Describe two advantages of using library routines in the program. Describe what is meant by a Dynamic Link Library (DLL). Three translators are compilers, interpreters, and assemblers. State one benefit of Kimmy using an interpreter during the development of the program. State three benefits of Kimmy using a compiler when the program is complete.

Annchi is writing a computer game with a group of friends. One of her friends has suggested using Dynamic Link Library (DLL) files to help them develop the game. Give three reasons why Annchi and her friends should use DLL files when developing the game. Give two reasons why Annchi and her friends should not use DLL files when developing the game. Each member of the group is creating a different part of the game. Each person needs to test their part of the game independently before they are combined. Identify the most appropriate type of translator that should be used to test each part of the game independently. Justify your choice. Translator Justification Annchi needs to decide which type of software licence to use for the game. Give two benefits to Annchi of using a commercial licence. Give one benefit to the customers of the game being released using a commercial licence. Describe one benefit to the customers of the game being released using a shareware licence.

Jackie is writing a program in a high-level language (HLL). The program makes use of Dynamic Link Library (DLL) files. Complete the following sentences about DLL files by writing the missing words from the list given below. closed corrupted directory edited errors executable opened recompile running tested validated verified The file does not contain the library routines. A DLL file can be without having to the calling program. One drawback of a DLL file is that the main program could stop working if the DLL file is . Jackie will use language translation software to run her HLL program. Identify and describe one type of language translator. Translator Description Explain the reasons why Jackie should copyright her program.

Kim is using her laptop computer to write a program in a high-level language. Kim needs to make sure the program is secure against unauthorised access. She has already set up a username and password on her laptop. Identify two additional electronic measures that Kim can use to keep the program secure. Kim will use library routines in her program. Describe what is meant by a library routine. Describe one benefit and one drawback of using library routines. Benefit Drawback Kim develops her program and makes it ready for use. To do this, she uses first an interpreter and then a compiler. Explain why Kim needs to use both an interpreter and a compiler. Interpreter Compiler

Three examples of language translators and four definitions are shown below. Draw lines to link each language translator to the correct one or more definitions. Definition Language translator The software reads the source code and reports all errors. The software produces an executable file. The software reads each statement and checks it before running it. The software halts when it encounters a syntax error. The software translates a high-level language program into machine code for the processor to execute. The software translates low-level statements into machine code for the processor to execute. Compiler Assembler Interpreter
