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.
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.
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.
An offer combining several products in one, usually containing a game console and games.
Dots per inch (DPI) indicates the number of dots in a printed inch.
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.
Wheel hardness ranges between 74A-100A. Softer wheels (78A-82A) are suitable for beginners. They grip surfaces better, absorbing any bumbs, but are also slower and wear out more rapidly. Harder wheels (82A or more) are suitable for more advanced skaters. They are faster and last longer, but they absorb less vibration, making them more difficult to handle.
Roller skates follow the same sizing system as US, UK or EU shoes. For EU sizes, it is recommended to choose a half to a whole number greater than the size of your feet. The skate should fit the foot well, without pushing on it. Some children's skates allow you to adjust the size by a few numbers.
Recirculation mode is used if your building does not allow air to be discharged into a chimney, i.e. typically in residential flats, prefabs and the like. In this mode, carbon filters are used to clean the air and remove odours. The cleaned air is then returned back into the room. Recirculation is slightly noisier than extraction.
USB cables and connectors are our constant companions, but the sheer variety and number of options can get confusing. Let's take a closer look at the most common USB types and see what the latest newcomer USB-C brings into the fray.
Expressed in hertz (Hz). Represents the number of frames per second that the screen can show. A larger value provides a smoother picture, which is especially important for sports, action movies and games. We recommend a refresh frequency of at least 100 Hz.
Hardware memory designed to speed up the process of accessing data from the main memory. The larger the value, the greater the speed. A normal value is 2 MB
The fan located in the rear wall of the oven circulates hot air and ensures faster heating. The hot air heating is enabled thanks to the turbine built around the fan. In this owen, food is cooked on several levels at once. Convection oven saves energy.
