Random-access memory (RAM)
RAM 16 GB

RAM is a short-term data storage. This component determining the operation speed:

  • allows the CPU of your computer to have fast access to the information that needs to be processed used by the computer application which you have opened;
  • at the moment of opening an application stores it in its microchips, thus the memory capacity determines how many applications can be run by your computer simultaneously and also with how big data volume (pictures, texts, webpages) you can operate at once.

Thanks to the dense placement of chipsets the RAM of a portable computer has the same characteristics as the RAM of desktop computers. Dateks.lv recommends to use 3Gb or higher capacity RAM for general use.

Wireless connections
Bluetooth Ir

Bluetooth connection provides secure wireless data transmission among various devices (at the distance of up to 150 m). This is a possibility for your portable computer to connect with your mobile phone, another portable computer, palmtop and other bluetooth devices without using any wires for exchanging Mp3 music, photos and documents. You can use bluetooth for connecting wireless headphones with a microphone, mouse, keyboard, printer and other devices supporting bluetooth connection.

Examples of use of the Bluetooth technology:

• transfer of files between computers or between a computer and another device;

• printing using Bluetooth enabled wireless printer;

• use of a Bluetooth equipped keyboard or mouse, listening to music via wireless headphones;

• synchronisation of the personal digital assistant (PDA) with a computer or another device;

• wireless connection to the Internet via the mobile phone or the modem server;

• connection to the Bluetooth personal network (PAN - this is the technology that allows to establish the Ethernet network with wireless links between portable computers, mobile phones and hand devices).

*For establishing a connection with a portable computer with bluetooth; all the devices to be connected need the bluetooth support.
