Which is the best definition of backup utilities?

• Provides a way to recover data if the original copy gets lost, deleted or corrupted
• Helps to consolidate the parts of the files back together
• Reduces the amount of space information takes up on a storage device
• Helps to detect and remove malicious programs

Which of the following is a disadvantage of closed source software?

Which is the best definition of compilation?

• The process of language statements being checked against the rules of the language
• Turns source code into machine code
• Translates intermediate code into machine code
• Turns Assembly code into machine code

Which is the best definition of lexical analysis?

• Puts each code statement into the form best suited to the syntax analyser
• The process of language statements being checked against the rules of the language
• The translation process that produces an equivalent program in a low-level language
• Ensures that executables programs are optimised at least as much as the compiler can predict

Which word should be used in this sentence? High level … can be translated into machine code using a compiler.

• Flowcharts
• Assembly code
• Source code
• Pseudocode

Which of the following is an advantage of open source software?

• Can be modified by the user
• Usually robustly tested
• Support must be paid for
• The finished quality of the software can be very varied

• Assembler
• Virtual machine
• Compiler
• Interpreter

Which is the best definition of the term 'linker'?

• A collection of pre-compiled routines which can be incorporated into a program
• Allows already compiled object code files or modules to be combined with the compiled program
• Copies an object program held on backing store into main store ready for execution
• The process of a virtual machine turning intermediate code into machine code
