Computer Chapter 1 : Test 5
1 / 20
Two processors are compared. One processes 32 bits of data at a time, while the other handles 64 bits in a single operation. The characteristic being compared is directly related to processor architecture.
Reasoning: Word size refers to the number of bits processed in one operation.
2 / 20
A smartphone stores application data using semiconductor-based memory components that offer fast access speeds and compact physical size. This category includes RAM, ROM, and flash memory technologies.
Reasoning: Chip memory is built using semiconductor technology.
3 / 20
An organization archives large volumes of information on devices that store data using magnetized surfaces. These devices are commonly found in desktop computers and servers for long-term storage.
Reasoning: HDDs are examples of magnetic memory.
4 / 20
A software company distributes its products using discs that are read by laser beams. Data is stored as microscopic pits and lands on the disc surface and accessed optically.
Reasoning: CDs and DVDs are examples of optical memory.
5 / 20
A user loses unsaved work after an unexpected power outage because the memory storing the information required continuous electrical power to retain its contents.
Reasoning: Volatile memory loses data when power is removed.
6 / 20
A computer stores operating system startup instructions in a memory type that preserves its contents even when the machine remains powered off for several months.
Reasoning: Non-volatile memory retains data without power.
7 / 20
A processor needs immediate access to instructions during execution. One type of memory communicates directly with the CPU, whereas another type stores data permanently and requires transfer through main memory before processing.
Reasoning: Primary memory is directly accessible by the CPU.
8 / 20
A database application frequently accesses active records stored in RAM rather than on a hard disk because rapid retrieval is essential for performance and responsiveness during processing.
Reasoning: Primary memory provides faster access than secondary memory.
9 / 20
A computer engineer compares RAM and HDD technology. One uses semiconductor chips while the other relies on magnetic recording surfaces for storing information.
Reasoning: RAM is chip memory; HDD is magnetic memory.
10 / 20
A sudden power failure causes all temporary processing data to disappear, while documents saved on storage devices remain available after restarting the computer.
Reasoning: Primary memory generally loses data when power is interrupted.
11 / 20
A student saves assignments on a storage device so that the files remain available after shutting down the computer and can be retrieved days or months later.
Reasoning: Secondary memory is used for long-term data storage.
12 / 20
A student turns on a computer and notices that the operating system loads automatically before any application can be opened. Later, he uses a word processor to type an assignment. Which statement correctly explains the relationship between the operating system and the word processor?
Reasoning: The operating system is system software that manages hardware and supports applications, while a word processor is application software.
13 / 20
A user connects a new printer to a computer. Although the printer is physically attached, it cannot print documents until specific software is installed. Which type of system software is required to enable communication between the printer and the operating system?
Reasoning: Device drivers allow the operating system to communicate with hardware devices correctly.
14 / 20
A school computer lab experiences slow performance because of unnecessary files occupying storage space. The technician uses a specialized program to remove temporary files and improve efficiency. Which category of software is being used?
Reasoning: Utility software performs maintenance tasks such as disk cleanup and optimization.
15 / 20
A programmer writes a program in C++ and wants the computer's processor to execute it. Before execution, the source code must be translated into machine language that the processor can understand. Which software performs this translation?
Reasoning: A compiler translates high-level language programs into machine code.
16 / 20
An engineer writes instructions using assembly language to control a specialized electronic device. Before the program can run, the assembly language statements must be converted into machine code. Which software is responsible for this task?
Reasoning: An assembler converts assembly language into machine code.
17 / 20
A large software project consists of several separately compiled modules. Before execution, these modules must be combined into a single executable program. Which software component performs this function?
Reasoning: A linker combines multiple object files into one executable program.
18 / 20
After a program has been compiled and linked successfully, it still cannot run until it is placed into the computer's memory. Which system software is responsible for loading the program into memory for execution?
Reasoning: A loader transfers executable programs into memory before execution.
19 / 20
When a computer starts, a small program stored permanently on the motherboard initializes hardware components and begins the boot process. Unlike ordinary software, it remains stored even when power is removed. What is this type of software called?
Reasoning: Firmware is permanently stored software embedded in hardware devices.
20 / 20
A user wants to protect a computer from malicious software and regularly scans the system for threats. Which category of system software typically provides this functionality?
Reasoning: Antivirus programs are utility software used to detect and remove malware.
