Dear aspirant,

Look at first you have to check the processor. Because it is the brain of a computer. It will tell you how to manage the ram.

Okay, let's talk about the question you have asked.

The minimum configuration is;

>> Intel i5(quad core is preferable)

>> 8gb ram(ddr4 is preferable)

>> Nvidia GeForce 940mx or mx 150( 2nd one is the best in the mid-range section)

Because i5 can manage every educational software. Quad core will be more faster than dual one. All the 8th gen intel model are based on 14nm chip rather than the 28nm of old one. And they provide Intel UHD integrated graphics instead of normal HD graphics. This is a good thing.

Hope it helps you..

Best of luck..
