The screens of portable computers are divided into Glare, or flossy and AntiGlare, or mat. The advantage of the flossy screen is better contrast, colours and sharpness, therefore this type of monitor is preferred by home users. The disadvantage of this screen is the glare which disturbs seeing the image in bright lighting.

AntiGlare, or mat screens to some extent prevent the glare problem by "scattering". This type of screen is usually used in business class computers intended for working with documents and accounting systems.

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. TopPC.ee recommends to use 3Gb or higher capacity RAM for general use.

AnSSD, or Solid State Drive, is a modern storage device that, unlike hard disk drives (HDDs), has no moving parts and stores all information on NAND memory chips. This is why SSDs are much more reliable, as they can withstand shock, vibrations and temperature changes much better. The main advantage is the high data transfer speeds as well as the lowaccess time. Currently, SSDs equipped with a SATA 3 port deliver data transfer speeds of 500 MB/s on average. However, some drives using M.2 or PCI-Express ports have data throughputs

2000 MB/s.

If you want to connect portable headphones or stand-alone, more powerful speakers to your computer you should certainly look for a computer with the connection slot for headphones.

If you don't make your choice at once later it will be necessary to buy an external sound card which is an additional expense and quite often not a very convenient solution.

This device allows to copy photos from the memory cards of digital cameras without connecting the camera. All you have to do is to insert the relevant card in the reader and all its content is available in the computer at the very same moment.

There are different types of cards (SD, MMC, xD, MS Pro, etc.), therefore you should verify whether the selected card reader supports the required type of the card.

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.

Wireless is the wireless network connection via which the computer will be connected to the router or the access point. Nowadays the 802.11 B/G/N connection with the highest speed operation (150 -300 Mb/s) and highest security is most popular.

Via 802.11 B/G it is also possible to connect to virtually all network, just the maximum speed will be 54 Mb/s in connections to the N type network.

This parameter determines whether the keyboard of the portable computer has a separate number pad. If you have to work with numbers and figures a lot you should certainly verify whether the selected computer has the numpad.

The battery time indicates the approximate time how long your portable computer will be able to operate after it has been disconnected from the electricity supply when the battery is fully charged.

The battery time depends on the configuration, performed operations and other factors. This indicator usually is based upon the testing results. The lithium batteries built-in modern portable computers usually provide the operation time of 3 to 5 hours and this time depends on the use and configuration of the computer. The maximum battery capacity reduces the time of use of the portable computer. Currently lithium batteries are used in computers and they replaced nickel batteries. It has to be taken into account that the lifetime of portable computer batteries is limited. The capacity decreases with time and it is necessary to replace the battery.

*The battery time may decrease depending on the loading of the portable computer during the time when the battery is used as the power supply to the computer.
