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.
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.
The Trusted Platform Module (TPM) is an encryption processor (cryptoprocessor). Encryption keys that protect data are stored on it. Laptops equipped with a TPM provide high levels of protection for stored data.
This is a modern port that lets you quickly charge your laptop, transfer data and connect up to two 4K monitors. The Thunderbolt 3 is based on the USB-C, sharing the shape of the connector.
HDMI stands for High-Definition Multimedia Interface. It offers digital output with integrated sound (or network transmission) and is often used to connect laptops with other devices, such as TVs. It enables multi-channel audio and can handle up to 4K resolution (HDMI 2.0).
Convertible laptops are devices with flippable or detachable displays. They are more flexible and lighter than standard laptops and offer several different modes 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.
Bluetooth is the communication tool used by a huge amount of electronics. Learn how the frequency signal is generated and how it's used. In a simple overview of the different versions, we will show how Bluetooth has evolved and been refined. You can also learn something about the specifications and security of this communication standard.
A laptop battery's size, along with the efficiency of the components used and software optimisation, determines battery life.
