Antireflexní displej je displej s povrchovou úpravou, která má zabránit odrazům okolního světla. Jak se ale liší od matného displeje, už nemusí být tak zřejmé. V tomto článku vám to vysvětlíme.

IPS, or In-Plane Switching, often also known as Super TFT, is a type of LCD display technology. It offers an excellent quality-price ratio, natural colours, low power consumption, and wide viewing angles up to almost 180 degrees.

A feature providing increased computer performance by overclocking without complicated settings in the BIOS.    

It is the function providing multi-threaded parallel processing instructions - from one physical processor are created two virtual processors. In practice this means that it significantly reduces the system response and at the same time accelerates the operations, which you require from the processor.  

The ability of the processor hardware to support full virtualization.  

Memory type represents a certain standard (eg. DDR3, DDR4), which defines the extent of the properties. What type is used in the assembly, is designed by motherboard, as it is not possible to use a different type than the motherboard supports.  

An integrated graphics card is embedded directly into the processor. While they do not achieve such high levels of performance as dedicated graphics cards, the battery of a laptop equipped with an integrated graphics card will last longer. Devices with this type of graphics cards are suitable for office work and multimedia entertainment, but they are not ideal for running graphics-intensive games and programs.

Prvá SSD jednotka bola vyrobená už v roku 1976, ale trvalo dlhých 35 rokov, kým sa cena dostala na takú úroveň, aby bolo možné jej masívne rozšírenie. Čo nám vlastne SSD prináša, aká je jeho spoľahlivosť a ako sa zapája?

M.2 is a standard connector for connecting internal components. It replaces the older mSATA standard. SSDs connected via M.2 can achieve higher read and write speeds.

The Trusted Platform Module 2.0 (TPM 2.0) is a hardware security component that allows a computer to perform hardware-level encryption. This is useful for protecting sensitive data and for performing functions such as BitLocker disk encryption on Windows systems.

High-Definition Multi-media Interface, digital output with integrated audio (or network transfer ) is commonly used in TVs, for example. The format enables transfer of 3D video and multichannel audio and can handle video in up to 4K resolution (HDMI 2.0)

RJ-45 (LAN) is the standard connector type used for Ethernet network interfaces. Through the LAN connector, a laptop can connect to a wired network, which can offer a more stable and often faster connection than a wireless network interface.

Ešte nikdy nebola rýchlosť WiFi taká dôležitá. Schválne si skúste spočítať, koľko máte doma bezdrôtovo pripojených zariadení. Určite ich nebude málo. A keď k tomu pridáte napríklad požiadavku na pohodlné streamovanie videa, on-line výučbu alebo home office, tak drvivej väčšine routerov dôjde dych. Preto je potrebné WiFi sieť nielen zrýchliť tak, aby zodpovedala štandardu WiFi 802.11ac. Čo všetko takýto štandard dokáže a čím sa líši od starších WiFi generácií?
