Denotes the distance between the lower left and upper right corner of the screen. It is quoted in inches,while 1 "= 2.54 cm. How big a diagonal measurement to choose with which device and what are the benefitsand the disadvantages?

The resolution specifies the number of pixels (pixels) that are displayed horizontally and vertically on a screen. The higher the resolution, the sharper and more detailed the image.

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.

One of the main parameters of the processor, indicating the number of instructions that the processor can execute in 1 s. The higher frequency, the better working efficiency of the processor.

The core is the most important part of the processor. It is responsible for all computing operations. Generally, the more cores, the more tasks can processor process at one time. At the same time,...

Hardware memory designed to speed up the process of accessing data from the main memory. The larger the value, the greater the speed. A normal value is 2 MB

Allows individual processor cores to run faster than the base frequency, assuming that circumstances (current consumption, temperature of cores) permit it. Intel processors are equipped with turbo...

TDP procesora (Thermal Design Power) je najvyšší možný tepelný výkon procesora, ktorý môže byť dosiahnutý pomocou štandardných aplikácií. Udáva, aké veľké množstvo tepla potrebuje chladiaci systém počítača odviesť od procesora, aby ho ochránil pred príliš vysokými teplotami, ktoré nebude schopný uniesť. Hodnota navrhnutého tepelného výkonu je výrobcom špecifikovaná pre každú súčiastku (procesory, ale aj grafické karty, a podobne). Vyššie TDP majú spravidla výkonnejšie procesory. S jeho vzrastajúcou hodnotou však rastú tiež nároky na chladenie. Jednotkou TDP je Watt.

One of the basic parameters of a graphics card. The greater the capacity, the more power potential. Cheaper graphics cards can have, for example, 512 MB, whereas gaming cards can have 4 GB or...

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

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?

Contains a list of basic equipment, which is supplied with the product. For sets, it is mostly a mouse with a keyboard or optical mechanics.

Accurately identifies the type of standard for a wireless network. The selected type has a great influence on the stability of the connection and transmission speed.  

Indicates the colour finish of the chosen device.

USB 3.0 is 10 times fater than its predecessor (with which it is backwards compatible). The maximum data transmission speed can be used with flash drives, portable drives and external drives that...
