Ultrabooks

The screen size is measured by the distance between the left bottom and top right corners of the display. The screen size is usually given in inches, with 1"= 2.54cm.

There are currently two main display technologies used - LCD and OLED - which are further divided into different subcategories.

Indicates the number of points (or pixels) that can be displayed in an image. It is calculated as the number of pixels in width × the number of pixels in height. The most popular resolution now is full HD 1920 × 1080, while HD / HD Ready (1366 x 768) is also common. 

Each type of display is suitable for different purposes.

Generally, the higher the number, the more powerful the processor. For an office PC, a basic processor series will be more than sufficient, but for more challenging work and gaming you will require a more advanced processor.

A more accurate label of the processor, which gives a detailed specification of the particular model. 

Dedicated graphics cards have their own integrated memory and are offered by established manufacturers such as NVIDIA and AMD. Integrated cards have lower power consumption and are particularly suitable for office work. Integrated Intel Iris cards often achieve better results than dedicated cards. 

The graphics card chip is the basic building block that determines the graphics performance of a device. Memory size (GB), speed (Mhz), and the number of processors play a key role in selecting a graphics card.

This parameter determines the maximum resolution supported by the device. It is specified as a multiplication of pixels at a maximum scanning resolution (e.g. 1920 × 1080).

Memory capacity indicates the maximum volume of data that the module operate with at one time.

Memory selection always depends on the motherboard, meaning the used chipset and what it supports. The most common type of memory is DDR3, but more modern motherboards now support the new DDR4 modules. What is the main difference between memory? The DDR3 has a maximum of 8 GB of RAM and operates at a maximum of 2133Mhz, while DDR4 can handle up to 16GB of RAM and operates at a maximum of 3200Mhz.

HDD and SSD drives are used for permanent storage of data on computers and laptops. But what are the differences between the two, and what are their advantages?

The capacity (size) of the hard disk determines how much data the disc can accommodate.  

The capacity (size) of the hard disk determines how much data the disc can accommodate.  

Determines the length time that a device can be used under normal conditions. Battery life depends on the type of usage, for example watching videos or working with demanding programs drains the battery faster than more basic functions.  

Convertibles are similar to classic laptops, but include a touchscreen and a hinge.

These connectors can be connected display device.

Displays a list of alternative connection options.      

Indicates the type of optical drive on the device. 

Determines the language localisation of the keyboard. For example, Czech keyboards feature Czech characters – ř, ů, ě, and so on.
