Digital Environments (Hardware and Software)

Front

What is the foundational duality of the modern digital environment?

Back

Hardware and software

Answer explanation

The foundational duality of the modern digital environment is hardware and software. Hardware refers to the physical components, while software encompasses the programs and applications that run on that hardware.

Front

Which type of computer prioritizes portability and battery life?

Back

Mobile devices

Answer explanation

Mobile devices are designed for portability and long battery life, making them ideal for on-the-go use. In contrast, embedded systems, personal computers, and servers prioritize other functionalities over portability.

Front

What is the primary role of servers?

Back

Continuous operation and concurrency

Answer explanation

The primary role of servers is to ensure continuous operation and handle multiple tasks concurrently, allowing them to serve many users and applications simultaneously without interruption.

Front

What type of operating system guarantees critical tasks complete within strict deadlines?

Back

Real-Time Operating System (RTOS)

Answer explanation

A Real-Time Operating System (RTOS) is designed to guarantee that critical tasks complete within strict deadlines, making it essential for applications where timing is crucial, unlike other OS types.

Front

What is the primary function of the Central Processing Unit (CPU)?

Back

Executing instructions

Answer explanation

The primary function of the CPU is executing instructions. It processes data and performs calculations, making it the core component that drives the operation of a computer.

Front

Which type of memory acts as volatile, high-speed storage for running programs?

Back

Random Access Memory (RAM)

Answer explanation

Random Access Memory (RAM) is a type of volatile memory that provides high-speed storage for data and programs currently in use, allowing for quick access and processing by the CPU.

Front

What is a key advantage of Solid-State Drives (SSDs) over Hard Disk Drives (HDDs)?

Back

Superior data throughput and lower latency

Answer explanation

A key advantage of SSDs over HDDs is their superior data throughput and lower latency, allowing for faster data access and improved overall performance, making them ideal for high-speed applications.

Front

What is the role of the Operating System (OS) in a computer system?

Back

Managing and coordinating resources

Answer explanation

The Operating System (OS) is crucial for managing and coordinating resources like CPU, memory, and I/O devices, ensuring efficient operation of the computer system. Other options do not represent the primary role of the OS.

Front

Which type of OS employs time-slicing to simulate simultaneous execution?

Back

Multitasking OS

Answer explanation

A Multitasking OS uses time-slicing to allocate CPU time to multiple processes, allowing them to run seemingly simultaneously. This is essential for efficient resource management and user experience.

Front

What is a key characteristic of embedded systems?

Back

Deterministic response times

Answer explanation

A key characteristic of embedded systems is their deterministic response times, meaning they can consistently respond to inputs within a predictable time frame, which is crucial for real-time applications.
