QCM : Fundamentals of Computer Programs and Systems — 9 questions

Questions et réponses du QCM

1. What is a program in the context of computer systems?

A physical device used to input data into a computer
An application designed for user entertainment
A set of hardware components that perform calculations
A sequence of binary instructions loaded into memory to perform specific tasks

A sequence of binary instructions loaded into memory to perform specific tasks

Explication

A program is defined as a sequence of binary instructions loaded into a computer's memory that enables the processor to perform specific tasks or operations, which is explicitly stated in the context.

2. What is the primary role of an operating system in a computer system?

Manage hardware resources and facilitate user interaction
Translate human languages into machine code
Create application programs like Word or Excel
Connect computers across a network,

Manage hardware resources and facilitate user interaction

Explication

The operating system manages hardware resources, facilitates communication between user and system, and ensures overall system functionality, which is fundamental for computer operation.

3. What is the primary role of an operating system in a computer system?

To perform user-specific tasks like word processing
To connect the computer to the internet
To develop application software and utilities
To manage hardware resources and facilitate user interaction

To manage hardware resources and facilitate user interaction

Explication

The primary role of an operating system is to manage hardware resources and facilitate user interaction, ensuring the system operates efficiently and users can communicate with the hardware and run programs effectively.

4. Which of the following is an example of application software?

Windows OS
Notepad
Device driver
BIOS firmware

Notepad

Explication

Notepad is an application program designed for text editing, while Windows OS is a system program, and device drivers or BIOS are system components.

5. How does application software differ from system software such as operating systems?

Application software is written in binary code, whereas system software is written in high-level languages.
Application software manages hardware devices, whereas system software is designed for user tasks.
Application software performs specific user tasks, while system software manages hardware resources.
Application software is only used in mobile devices, while system software is used in computers.

Application software performs specific user tasks, while system software manages hardware resources.

Explication

Application software is designed to perform specific tasks for users, such as editing documents or creating images, with examples like Notepad and Paint. In contrast, system software like operating systems manages hardware resources and provides a platform for running application programs. Therefore, the key difference lies in their purpose: applications serve user tasks, while system software manages the system itself.

6. What does binary code consist of?

Sequences of 0s and 1s that represent instructions and data
Ping-pong balls used in hardware testing
Machine language instructions written in assembly
Sequences of letters and characters in programming languages

Sequences of 0s and 1s that represent instructions and data

Explication

Binary code is the fundamental language of computers, made up of sequences of 0s and 1s that represent instructions and data.

7. Which of the following is NOT considered a core function of the operating system?

Facilitating communication between user and system
Creating application programs like Word or Paint
Managing program execution and memory
Reading and writing data to external storage devices

Creating application programs like Word or Paint

Explication

Creating application programs is not a core function of the operating system; instead, the OS manages execution, resources, and data management.

8. What is included in a 'system of calculation' or computing system?

Hardware, peripheral devices, and software programs
Only the central processing unit (CPU) and memory
Network connections and internet services only
Human operators controlling the hardware

Hardware, peripheral devices, and software programs

Explication

A computing system includes hardware, peripheral devices, and programs working together to ensure operation, not just the CPU or network connections alone.

9. Which statement accurately describes a program?

A sequence of binary instructions loaded into memory that enables tasks to be performed
A physical hardware component that processes data
An external device used to input data into the system
A network protocol used to communicate between computers

A sequence of binary instructions loaded into memory that enables tasks to be performed

Explication

A program is a sequence of instructions stored in memory, which, when executed, allows the computer to perform specific tasks.
