Encoded machine instructions never operate directly on data.
Which of the following statements is true? You may select more than one.
Interpreted programming languages can not be compiled into encoded machine instructions.
Interpreters read programs from files and generate encoded machine instructions stored in other files for later execution.
Interpreters convert programs written in one programming language into another programming language.
All programs contain encoded machine instructions suitable for execution directly by a CPU.
Note: It is recommended that you save your response as you complete each question.Explanation / Answer
Solution 1:
Metadata is some information about the file in filesystem. it tells about the date of creation, modification, length of the file, author, etc. but not non-volatile memory containing the bytes in the file.
Thus, the correct option is A). Non-volatile memory containing the bytes in the file.
Solution 2:
GUI interface systems always provide file systems. With command line interpreters, user interpreters can also be provided to take user inputs and to show outputs. Operating system process is a well-defined term. But sometimes, task is also used in the place of process when task is about a single unit of the program.
Thus, the correct options are A) Systems that provide a graphical user interface always provide a file system., B) User interfaces may be provided by command line interpreters., D) The terms, "operating system task" and "operating system process" are often used interchangeably.
Solution 3:
The fastest accessible memory out of the given options is Cache RAM.
Thus, the correct option is C) Cache RAM.
Solution 4:
Magnetic tape, Spinning magnetic disk drive, paper tape are non-volatile memory whereas Cache RAM, FLASH RAM, Swap File, RAM disk are volatile memory.
Thus, the correct option is C) Virtual Memory, Resident Memory, Swap file.
Solution 5:
Databases cannot be implemented using file systems.
Thus, the correct option is A) Databases may be implemented using file systems, and file systems may be implemented using databases.
Solution 6:
Many OS include more than one filesystem, but not all.
Thus, the correct option is B) Operating systems always include one or more file systems.
Solution 7:
Encoded machine instructions provide information about the operands, operations etc.
Thus, the correct option is B) Encoded machine instructions are a kind of information.
Solution 8:
Machine instructions are always directly executed by CPU.
Thus, the correct option is D) All programs contain encoded machine instructions suitable for execution directly by a CPU.
