Az elektroakusztikus átalakító az akusztikus lánc egyik eleme, amely aktívan alakítja át az elektromos jeleket akusztikus hangokká (különálló hangfal kabinet nélkül), vagy épp ellenkezőleg, az akusztikus hullámokat elektromos jelekké (mikrofon, érzékelő, stb.)
Backlight bleeding is a phenomenon seen in LCD monitors, which is characterized by uneven backlight illumination, especially in dark scenes with minimal ambient illumination. It occurs mainly in IPS panels around the corners or edges. Sometimes this is called IPS glow or light bleeding.

A dedicated graphics card is located on the motherboard of a laptop in the form of a separate chip. Compared to an integrated graphics card, it's more powerful, so it's better suited for playing games and working in graphics heavy applications. However, dedicated graphics cards require more efficient cooling and reduce battery life. They are usually found in larger and heavier laptops.
Laptop adapters are used to power and charging a laptop's battery. In addition to the adapter provided by the manufacturer, it is possible to use other models. It is crucial to select an adapter with the correct connectors. What are the basic types?
Single-sided scanning. The device can scan only one side of the inserted document. To scan the other side, you have to flip and reinsert the page.

A cache stores data for quicker acccess in the future. It's advantagous because it increases speed and shortens access time. They can be found in processors and hard drives.
During exposure you expose the camera sensor to light emitted by the captured scene. Exposure is defined by three basic parameters, which are sensitivity (ISO), aperture (F), and exposure time. The higher the maximum ISO and the lower minimum aperture, the less time you need to capture the shot and the easier it is to avoid blurring. This comes in handy if you like to photograph sports, racing, and other objects in motion, or like shooting night-time scenery.
Climate classes (T, ST, N, SN) indicate the optimal outdoor temperature in which a freezer will operate. If the outdoor temperature is outside of the recommended range, the freezer's energy consumption increases, which may affect its performance. If a freezer is designated two or more climate classes, this means it will function throughout the whole temperature range. For example, a freezer designated SN-N-ST will operate in an ambient temperature of 10-38 °C.
Z-Wave is the perfect tool for automated smart home appliance management and plays a dominant role in the Internet of Things (IoT). Its key benefit is the ability to use the devices of different manufacturers while maintaining their mutual compatibility and ease of use.
The diagonal is the distance between two opposite corners of the screen, indicating the overall size of the display. It is usually written in inches (″) and does not include the variously wide screen bezels, so the final size of the device is usually slightly larger.
