Sample UP Police Computer Operator Practice Questions

Try these sample questions to test your UP Police Computer Operator exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which of the following components constitute the central processing unit (CPU) of a computer system?
A.Arithmetic Logic Unit (ALU) and Control Unit (CU)
B.Input Unit and Output Unit
C.Control Unit (CU) and Primary Storage Unit
D.Arithmetic Logic Unit (ALU) and Secondary Storage Unit
Explanation: The Central Processing Unit (CPU) is primarily made up of the Control Unit (CU) and the Arithmetic Logic Unit (ALU). The CU controls the flow of data and instructions, while the ALU performs all arithmetic calculations and logical comparisons.
2Arrange the following memory types in descending order of their access speeds (from fastest to slowest): Cache Memory, CPU Registers, Magnetic Disk, Random Access Memory (RAM).
A.RAM > Cache Memory > CPU Registers > Magnetic Disk
B.CPU Registers > Cache Memory > RAM > Magnetic Disk
C.Cache Memory > CPU Registers > RAM > Magnetic Disk
D.CPU Registers > RAM > Cache Memory > Magnetic Disk
Explanation: CPU registers are located inside the processor and have the fastest access speed. Cache memory (L1, L2, L3) is located on or near the processor chip and is slightly slower than registers but faster than main memory (RAM). Magnetic disks are mechanical secondary storage devices and are the slowest among these.
3In an operating system, which component is responsible for transitioning a process from the 'Ready' state to the 'Running' state?
A.Medium-term Scheduler
B.I/O Traffic Controller
C.Dispatcher
D.Long-term Scheduler
Explanation: The Dispatcher (part of the short-term scheduling subsystem) is responsible for allocating the CPU to the process selected by the short-term scheduler, moving it from the Ready state to the Running state.
4In operating systems, which disk scheduling algorithm services requests by moving the disk arm continuously from one end of the disk to the other, reversing direction only when it reaches either end?
A.Shortest Seek Time First (SSTF)
B.First-Come, First-Served (FCFS)
C.C-SCAN (Circular SCAN)
D.SCAN (Elevator) Algorithm
Explanation: The SCAN algorithm, also known as the elevator algorithm, moves the disk arm in one direction servicing requests until it reaches the end, then reverses direction and services requests as it sweeps back. This matches the behavior of an elevator.
5In a Linux/Unix operating system, what permissions are represented by the octal notation '754' on a file?
A.Owner: Read, Write, Execute; Group: Read, Execute; Others: Read only
B.Owner: Read, Write, Execute; Group: Read, Write; Others: Execute only
C.Owner: Read, Write; Group: Read, Execute; Others: Write only
D.Owner: Read, Execute; Group: Read, Write; Others: Read, Execute
Explanation: In octal permission notation: 7 represents read/write/execute (4+2+1=7) for the owner; 5 represents read/execute (4+0+1=5) for the group; and 4 represents read-only (4+0+0=4) for others.
6Which electronic component was primarily used in the circuit design of First Generation computers (e.g., ENIAC, UNIVAC)?
A.Very Large Scale Integration (VLSI) Microprocessors
B.Vacuum Tubes
C.Transistors
D.Integrated Circuits (ICs)
Explanation: First-generation computers used vacuum tubes for circuitry and magnetic drums for memory. They were massive, consumed huge amounts of electricity, and produced high heat.
7In virtual memory systems, what is the term used to describe the state where a system spends more time swapping pages in and out of memory than executing actual instructions?
A.Fragmentation
B.Deadlock
C.Thrashing
D.Page Faulting
Explanation: Thrashing occurs when the operating system spends a high percentage of its time page-faulting and swapping pages in and out of memory instead of executing user instructions. This usually happens when the active working set of processes exceeds physical memory.
8Which page replacement algorithm in virtual memory systems can exhibit Belady's Anomaly (where increasing physical page frames results in more page faults)?
A.Least Recently Used (LRU)
B.Optimal Page Replacement (OPT)
C.Most Recently Used (MRU)
D.First-In, First-Out (FIFO)
Explanation: Belady's Anomaly states that for certain page-reference patterns under the FIFO page replacement algorithm, the number of page faults may increase when more page frames are allocated to the process. Stack-based algorithms like LRU and OPT do not suffer from this anomaly.
9Which of the following devices is classified strictly as a computer output device?
A.Plotter
B.Scanner
C.Light Pen
D.Digitizer
Explanation: A plotter is an output device that prints high-quality vector graphics on paper using automated pens. Scanners, light pens, and digitizers are input devices used to capture drawings, coordinate selections, or documents.
10Which of the following is NOT a standard mechanism for Inter-Process Communication (IPC) in modern operating systems?
A.Semaphores
B.Instruction Pipeline
C.Shared Memory
D.Message Passing
Explanation: An instruction pipeline is a hardware level optimization technique used within the CPU instruction cycle (fetch, decode, execute) to speed up instruction execution, not an operating system IPC mechanism. Shared memory, message passing, and semaphores are standard IPC models.
