Hardware vs. Software basics.

Correct answer: A. Slow data transfer begins to hold back the whole system

In an input output bottleneck storage or device speed can limit the system even with a fast processor. For exams understand whole system speed.

Correct answer: A. It gives software a way to use graphics hardware services

A graphics API helps communication between app and graphics driver. For exams understand API as communication between programs.

Correct answer: A. To adapt software commands for graphics hardware

Graphics driver can act like a translator between app and graphics processor. For exams treat driver as a middle link.

Correct answer: A. Delay in sound input or output

Audio latency can be affected by hardware buffer driver and software setting. For exams treat it as a mixed cause topic.

Correct answer: A. It can affect delay and stability

A small buffer can reduce delay but may reduce stability sometimes. For exams understand the relation between settings and performance.

Correct answer: A. Device permission relates to hardware use and file permission to data access

Camera permission controls device use and file permission controls reading or changing files. For exams separate access types.

Correct answer: A. A low permission program gaining higher rights

Privilege escalation is a security threat that can affect system control. For exams read permission levels carefully.

Correct answer: A. At the early software level during system startup

Secure boot helps run trusted boot software. For exams connect it with UEFI and startup security.

Correct answer: A. It can hide at a deep control level of the system

A rootkit can secretly affect system control and security. For exams treat it as a deep software threat.

Correct answer: A. To protect security keys or perform cryptographic work

A hardware security module can be a special device for security tasks. For exams remember hardware role in security too.

Correct answer: A. One can be done by program and the other by special hardware

Encryption can be done by software or special hardware. For exams check the medium even when the work is similar.

Correct answer: A. Stored identity data

A biometric template can be a digital form of a sample taken by sensor. For exams separate sensor hardware and template data.

Correct answer: A. Sensor is hardware and algorithm is software process

Sensor captures the sample and algorithm performs matching. For exams distinguish input device and processing.

Correct answer: A. Hardware resources and software processing work together on a nearby device

In edge computing data can be processed near its source. For exams understand the role of location and resources.

Correct answer: A. It helps basic control and communication of a small device

In Internet of Things devices firmware makes hardware perform special tasks. For exams remember firmware in small smart devices.

Correct answer: A. Sensor data is measurement and driver is software that runs sensor with system

Sensor hardware gives measurement and driver connects that hardware with the system. For exams separate data and control software.

Correct answer: A. Software based digital model of a physical object

A digital twin can be a model based on data from a real object. For exams treat it as a digital model separate from real hardware.

Correct answer: A. API can give standard communication and driver controls a specific device

API is a way of software communication and driver makes hardware work. For exams separate roles of both interfaces.

Correct answer: A. Device starts working poorly after a new driver

Rollback can return to an older stable driver. For exams remember previous version when a problem comes after update.

Correct answer: A. Event time and error message can indicate cause

Logs are software records that can indicate hardware or driver errors. For exams understand the role of records in diagnosis.

Correct answer: A. To view records of system events and errors

Event records can help find problems. For exams treat such tools as part of software diagnosis.

Correct answer: A. It reads data from sensors and shows report on screen

Temperature measurement comes from hardware sensor and software displays it. For exams distinguish measurement and display.

Correct answer: A. Operating system uses network card through driver

Network card is hardware and driver is the software link. For exams understand interdependence as device and control.

Correct answer: A. Whether it is physical device data control instruction or interface

In hard questions device data setting service and interface can be different. For exams look at role not only name.

Correct answer: A. To create different permission levels in a system

Privilege rings help run software at controlled permission levels. For exams connect this with security and kernel control.
