Sieť GSM bola vo svojom období revolúciou a používa sa aj dnes

Telekomunikačný štandard GSM bol vo svojom období prevratným. Okolo roku 2010 ho využívalo asi 90 % trhu a volať či pristúpiť na internet cez neho dokázalo takmer každé zariadenie. Od siete druhej generácie (2G) sme však už prešli dlhú cestu. Prečo teda štandard GSM stále funguje a ako to s ním bude do budúcnosti?

Ako spoznať príslušenstvo s certifikáciou MFi?

Čo si predstavíte pod pojmom MFi? Tí z vás, ktorí používajú Apple zariadenia, už možno tušia. Áno, ide o certifikáciu, ktorou je označené výhradne kvalitné príslušenstvo. Ako ho spoznáte?

Operačný systém: Android

Android je operačný systém vyvíjaný spoločnosťou Google, ktorý v súčasnosti používa väčšina výrobcov mobilných telefónov. Ide o tzv. otvorený operačný systém a má prakticky neobmedzené možnosti prispôsobenia. Niektoré úpravy je možné vykonať pomocou základných nastavení, zatiaľ čo ďalšie modifikácie si môžete kedykoľvek stiahnuť z obchodu Google Play. Používateľ tak môže veľmi jednoducho upravovať nielen grafické rozhranie, ale aj spôsob ovládania telefónu. Slabšou stránkou systému Android je jeho vyššia náchylnosť na napadnutie škodlivým softvérom. Podrobnejšie sa popisu jednotlivých OS, ich výhod a nevýhod venujem v článku Porovnanie mobilných operačných systémov.

RAM

Operational memory, or RAM, is a quickly accessible memory that stores the data being processed. In general, the larger the operating memory of the device, the faster it runs and handles more operations at once.

Display refresh rate

The display refresh rate indicates how many times per second the screen image is redrawn. A higher number means a smoother turnaround. The normal frequency is 60 Hz and you may notice a slight tearing on it when scrolling quickly. It does not occur at refresh rates of 90, 120 or more Hertz.

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.

Project Treble

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.)

NFC

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.

Virtual Reality

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.

Ingress Protection (IP)

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.

USB-OTG

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.
