Hardware vs. Software basics.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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