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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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?

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?

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?

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?

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?

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?

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?

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?

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?
