Az Android a Google által kifejlesztett operációs rendszer, amelyet jelenleg a legtöbb mobiltelefon-gyártó használ. Ez egy nyílt operációs rendszer, amely gyakorlatilag korlátlan testreszabási lehetőségekkel rendelkezik. Egyes módosítások az alapbeállítások segítségével végezhetők el, míg más módosítások bármikor letölthetők a Google Play áruházból. A felhasználó így nagyon könnyen módosíthatja nemcsak a grafikus felületet, hanem a telefon kezelésének módját is. Az Android gyenge pontja a rosszindulatú támadásokra való nagyobb fogékonyság. Az egyes operációs rendszerek részletesebb leírása, előnyeik és hátrányaik a Mobil operációs rendszerek összehasonlítása című cikkben található.
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.
Treble is a project aimed at making Android update times faster by separating part of the operating system from vendor implementation to a new vendor interface. Treble provides some of the updates (security patches, kernel, etc.) for the device by Google rather than from the Android OS framework. The second part of the update is provided by the device-specific original vendor (graphical superstructure of the user environment, vendor specific system applications, etc.)
Spyware is used to detect malicious software (malware) that hackers use to spy on users. They gain access to your personal data, banking data, and your online history. How can you get rid of spyware and how can you protect yourself against it?
Plastic SIM cards are already dying a slow death. The future is eSIM technology. It is a separate chip that is built into the phone. What will change from using plastic SIM cards? Does the new modern eSIM technology have any pitfalls?
LTE can be seen every day on mobile phones or ads. But do you know what LTE actually is? Do you know the advantages of LTE over older 3G networks? And what is the difference between LTE and 4G?
Pure Android is an operating system for mobile phones with Android in its simplest form - it does not include an adjusted graphical interface or any features that are added to the operating system expansion by the individual manufacturers.
NFC (Near Field Communication) is a wireless communication used to establish a connection between portable devices, over a very short distance, only up to 4cm. Previously, NFC was used to transfer photos and videos, but you'll often hear about it in connection with contactless payments.
VR or virtual reality is a hardware and software simulated environment that gives users the illusion of the real world. VR is usually used within the mobile and computer segments and can simulate game environments as well as training programs (e.g. pilot training, combat training, etc.). Virtual reality is viewed using special glasses and powerful hardware is required, usually your computer or phone.
The ingress protection (IP) is an internationally standardised code that identifies the resistance of electrical appliances against the ingress of foreign items and liquids, especially water. It is expressed in the so-called IP code, which consists of the "IP" followed by two digits: the first indicates the protection against dangerous contact and foreign objects, the second indicates the degree of protection against water ingress.
You can connect your phone to external devices via USB-OTG (On-The-Go). Devices such as flash drives, SD card readers, mice, keyboards, game controllers etc.
GLONASS is the Russian equivalent of the American GPS system. If a phone uses a combination of GPS and GLONASS, it provides more precise location information and faster localisation.
A-GPS downloads data from the mobile network about the satellites precise orbit and thus accelerates the localisation process after the GPS is turned on.
GPS is an American positioning system that can determine your position on or above the ground within the accuracy of a few meters. It can also be used to measure distance and time.
The motion of a gyroscope rotates in space on all three axes. In this case, it determines the direction in which you are moving your phone.
Accelerometers and G-Sensors are motion sensors that determine the tilt in space. The phone uses it to know which way it is being held, e.g. portrait, landscape or upside down.
LTE (Long Term Evolution) marks the next generation of mobile data networks. This is an intermediate step between 3G and 4G. Although manufacturers and operators sometimes mistakenly refer to it as 4G, it is not a full 4G network. That's for LTE Advanced. The maximum theoretical data transfer rate is up to 175Mbps for download and up to 57.6Mbps for sending data in one frequency band.
In regards to technology-electronics, there are several different displays commonly found: TFT, IPS, and AMOLED.
TFT (Thin Film Transistor)
This is commonly found in cheap mobile phones. An advantage is its low production cost. Disadvantages include the narrow viewing angles, low-quality contrast and long response time.
IPS (In-Plane Switching)
This is also sometimes referred to as Super-TFT. It's used on both mid and high-end smartphones. It has much less flaws when compared to older TFT displays. IPS provides accurate colour reproduction and wide viewing angles.
AMOLED (Active-Matrix Organic Light-Emitting Diode)
This is currently the most advanced display on the market. With declining production costs, it can now be found on ma
Platform and operating system are to some extent very similar terms, but not entirely. An operating system (OS) is a software running smartphones, computers, laptops and tablets. Google Android or Apple iOS are most common for mobile phones and tablets. You can find out more detailed information about each OS as well as their advantages and disadvantages in our Comparison of Mobile Operating Systems article. When referring to Android and iOS as platforms, we're talking about a package of services associated with them, such as Gmail for Google or iTunes for Apple. These services can be used not only on mobile devices, but also on computers and laptops.
