How to choose a computer?

Are you willing to invest in buying a computer to serve you for 10 years? Will you use it using a battery without an electricity connection? How large and heavy portable computer will be right for you? How large display will allow you to work faster on an office computer? Do you want a gaming computer with a dedicated graphics card for medium-demanding games or a gaming computer with two dedicated graphics cards that can handle the most demanding games at high resolution? How will you find out which computer components are powerful and which are not?

What should you avoid?

Are you buying a computer without an optical drive, but want to play a CD / DVD on it? Are you buying a computer without a USB-C port and still want to use it? Are you buying a quality computer that will be slowed down by one low-quality component? Are you buying a powerful computer that has a poor quality display/monitor? Are you buying a computer that will consume a lot of electricity? Are you buying a portable computer with a low battery capacity that drains quickly? Are you buying a 10-inch tablet that does not fit in your handbag? Are you buying a powerful computer that has a slow HDD? Are you buying a gaming computer with an integrated graphics card? Are you buying a computer with a powerful or energy-efficient graphics card?

Desktop computers

The most powerful computers for home use take up the most space. They consist of a separate monitor - usually with a screen diagonal of 24 - 32 inches (61 - 81 cm). A computer case contains the motherboard, processor, RAM, SSD or HDD, graphics card, optical drive, power supply unit, and more. Some computer components need to be powerful, others don't, depending on what you use it for. Some computers need a fast processor, others a fast graphics card, others a fast SSD or a large RAM.

All-in-One computers

All-in-One computers are located directly in the body of the monitor, these are mostly office computers. You connect a keyboard, mouse and you can work with a complete computer. The screen diagonal is usually 20 - 28 inches (51 - 71 cm).

Portable computers with battery

Laptops are portable computers that have slightly lower performance than desktop computers. The main disadvantage over desktop computers is the smaller diagonal of the display, usually 15.6 or 17.3 inches (40 or 44 cm). Tablets are devices mostly with a diagonal of 8 or 10 inches (20 or 25 cm) and usually without a keyboard. The tablets use 5G or 4G LTE internet, but some models only have a WiFi connection. Some tablets can also be used to make phone calls and send text messages.
