What to look for, before buying a laptop for programming, gaming etc?
What is the difference in the processors?
Simply the three processors I3, I5 and I7 differ in speed and efficiency. I7 have the maximum performance then I5 and then I3. But technically I3 processors generally have two cores while I5 generally have four cores (exceptions exist) and uses robust Turbo boost Technology. I7 processors also generally have four processors (exceptions exist) only but are designed in much better way compared to I5 processors. So that was a brief difference on difference in Intel processors.

What is the difference between various generation of a single processor?
The different generations of a processors have differences in clock speed (Number of clock cycles a CPU can perform per second, simply the GHz thing in the processor), fabrication technology (the technology used to make the integrated circuits for the processor). Some of the generations might differ in number of cores also.
For example if we take Core I7 processor, the 3rd generation is built on 22nm technologY whereas 5th and 7th generation are built on 14 nm technology.
I just wrote about this briefly, to know more you can visit: Intel Core
Coming to Razon processors i will suggest AMD Ryzen 3 2200G processors for entry level otherwise buy AMD Ryzen 5 2600X which the best mid level processor. If you have very good budget then you can take AMD Ryzen 7 2700X which is the one of the best processors.

I hope you understood about Processors, comment below if you have any doubts.
What does RAM do?
As we all know that all the softwares are stored in your storage but these applications load on RAM. When you switch on your PC and start different applications, all those applications load and run on your RAM. So, with increase in RAM your laptop speed also will increase.
I recommend 8GB RAM for beginners and it is good enough for most of the people. You can go 16GB depending on your needs.
