Electrical Power Input

Electrical power input is the amount of power that flows from the socket or power supply. The output is always lower than the input. This is where the concept of perpetual motion comes into play, because there will always be some energy loss (thermal, motion or sound). This creates the difference between input power and output power.

Backlight bleeding

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.

DIN Classification

The DIN 66399 classification system defines the maximum particle size of shredded material for a given security level. The higher the classification degree, the smaller the strips or particles of shredded material.

WiFi 802.11ac

Standard 802.11n – WiFi 4 kann in beiden Bändern (2,4 und 5 GHz) kommunizieren und dank der MU-MIMO-Technologie (Multi-User Multiple Input Multiple Output), die eine solide tatsächliche Geschwindigkeit bietet, ist die MU-MIMO-Technologie hier besonders wichtig, da sie es dem WiFi-Router ermöglicht, mit mehreren Geräten gleichzeitig mit hoher Geschwindigkeit zu kommunizieren.

Anti-reflective Display

Ein entspiegeltes Display ist ein Display mit einer Oberflächenbehandlung, die Reflexionen durch das Umgebungslicht verhindert. Aber der Unterschied zu einem matten Display ist vielleicht nicht mehr so offensichtlich. In diesem Artikel werden wir Ihnen dies erklären.

Dedicated Graphics Card

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.

Types of Laptop Adapter Connectors

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?

Simplex

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.

Luminous Flux

Luminous flux expresses the amount of light that comes from the source and is measured in lumens. Different wavelengths of light and the sensitivities of the human eye are taken into account. Simply put, more lumens means brighter light and less lumens means dimmer light from your lightbulb.

Bowl

A space designed for skateboarding that resembles an empty swimming pool.

Cache

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.

Exposure

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 Class

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

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.

Screen Size

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.

4K Resolution (Ultra HD)

4K technology offers four times the detail when compared to FullHD, so when you look at your favourite movie on a 4K TV, you'll find details you've never seen before.

Was ist ein Bundle?

An offer combining several products in one, usually containing a game console and games. 

DPI

Dots per inch (DPI) indicates the number of dots in a printed inch.

OLED Display

Often dubbed the display of the future, OLED displays are usually found on premium products. They offer high quality, a broad range of colours, low power consumption, high brightness, and excellent black colour reproduction. As a result, OLED displays are easy to view even in bright sunlight. Another advantage is the wide viewing angle, which reaches nearly 180 degrees.
