Sample Maharashtra HSC Computer Science (Bifocal) Practice Questions

Try these sample questions to test your Maharashtra HSC Computer Science (Bifocal) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In Maharashtra HSC Bifocal Computer Science, an operating system primarily acts as an interface between the user and the:
A.Application marketplace only
B.Computer hardware
C.Web browser cache
D.Printer firmware alone
Explanation: Standard OS definition in Paper I: the operating system is system software that manages hardware and provides an environment for users and applications to run.
2Which of the following is a core function of an operating system?
A.Writing HTML tables for a webpage
B.Process and memory management
C.Drawing schematic circuit diagrams
D.Compiling only 8085 assembly
Explanation: OS functions in the bifocal syllabus include process management, memory management, file management, device management, and security/access control.
3In memory management, dividing physical memory into fixed-size blocks and mapping logical pages onto them is called:
A.Segmentation only
B.Paging
C.Spooling
D.Thrashing
Explanation: Paging divides memory into equal-size pages/frames and maps logical addresses to physical frames — a key OS memory-management concept in Paper I.
4Virtual memory allows a process to:
A.Execute only from ROM chips
B.Use more address space than physical RAM by using secondary storage
C.Disable all interrupts permanently
D.Run without a CPU
Explanation: Virtual memory combines RAM and disk (swap/page file) so processes can address more memory than installed physical RAM, under OS control.
5Which statement best distinguishes a GUI from a CLI?
A.GUI uses only binary machine codes typed by the user
B.GUI provides graphical icons/menus; CLI uses typed text commands
C.CLI always requires more RAM than any GUI
D.GUI cannot open files while CLI can
Explanation: OS user interfaces: Graphical User Interface (windows, icons, menus) versus Command Line Interface (text commands), both covered in Paper I OS chapters.
6A process in the running state is currently:
A.Waiting only for user login forever
B.Executing on the CPU
C.Deleted from the process table
D.Stored solely on magnetic tape offline
Explanation: Process states include new, ready, running, waiting/blocked, and terminated. Running means the process has the CPU and is executing instructions.
7In multiprogramming, the main goal of keeping multiple processes in memory is to:
A.Force every process to use the same address
B.Increase CPU utilization by overlapping I/O wait of one process with execution of another
C.Eliminate the need for secondary storage forever
D.Disable device drivers
Explanation: Multiprogramming improves CPU utilization: while one process waits for I/O, another ready process can run.
8Segmentation in memory management divides a program into:
A.Equal-size frames only
B.Logical units such as code, data, and stack segments of variable size
C.Only password hashes
D.Fixed 512-byte disk sectors exclusively
Explanation: Segmentation maps logical segments (often variable length: code, data, stack) rather than fixed-size pages.
9Which access-control idea best matches OS security teaching at HSC bifocal level?
A.All users should share one unrestricted root password publicly
B.Users and programs receive only the privileges needed to perform authorized tasks
C.Firewalls must be removed to improve security
D.File permissions should always be world-writable
Explanation: Access and security aspects of the OS emphasize authentication, authorization, and least privilege so users/processes cannot freely access every resource.
10Spooling is best described as:
A.An HTML list type
B.Simultaneous peripheral operation online — buffering I/O jobs (e.g., print) on disk for later device handling
C.An 8085 addressing mode
D.A sorting algorithm for arrays
Explanation: SPOOL commonly expands to Simultaneous Peripheral Operation Online: the OS queues device jobs (classic example: print spooler) so the CPU is not blocked waiting on slow peripherals.
