Operating System Basics Questions and Answers
Operating System Basics questions with answers are among the most commonly asked in technical interviews and exams. This section covers core OS concepts like process management, memory allocation, file systems, and scheduling algorithms. Practicing programming questions and answers on operating systems helps strengthen your conceptual clarity and practical understanding of computer architecture. Frequently featured in GATE, TCS, Infosys, and Wipro placements, these MCQs provide a balanced mix of theoretical and applied knowledge. Clear explanations make this section an ideal resource for anyone preparing for system-related roles or competitive exams.

531. Fragmentation of the file system
- can always be prevented
- Occurs only if the file system is used improperly
- can be temporarily removed by compaction
- is a characterstic of all file systems
532. File record length
- should always be fixed
- should always be variable
- depends upon the size of the file
- should be chosen to match the data character
533. Disaster recovery
- is needed by every installation
- is never needed
- varies in degree between installations
- requires off site computer for immediate use
534. Wild-card specifies
- provide an easy way of finding groups of related files
- are only used when printing the contents of files
- can be used when writing a file
- allow several files to be read simultaneously
535. The allocation map
- is used to store program data
- specifies which blocks are used by which file
- is update by applications programs
- allows programs to erase files
536. The activity of a file
- is a low percentage of number of records that are added to or deleted from a file
- is a measure of the percentage of existing records updated during a run
- refers to how colsely the files fit into the allocated space
- is a measure of the number of records added or deleted from a file compassed with the original number of records
537. The volatility of a file refers to
- The number of records added or deleted from a file composed to the original number of records in that file
- Efficiency with which non-sequential files are processed
- The extent where the records of thefile are contiguous and in proximity to others
- Percentage of records that has changed in a given time period
538. Which types of file orgaanization are supported by magnetic tape ?
- random files
- contiguous sequential file
- indexedsequential file
- all of the above
539. Address Binding id defined as
- Compiler wil typically bind these symbolic addresses to relocatabe addresses
- Each binding is a mapping from one address space to a another
- The linkage editor or loader win in turn bind these relocatable addresses to absolute addresses
- All of the above
540. Compile time
- Where the process will reside in memory, then absolute code can be generated.
- Where the process will reside in memory, then the compiler must generate relocatable code.
- If the process can be moved during its execution from one memory segment to another, the binding must be delayed until run time
- All of the above
