Where can I read about highload to a person who has never encountered this?

Question

Highload

Good afternoon, colleagues! I am engaged in web development, very often I come across mentions of highload projects, I see knowledge of highload projects as a requirement in many companies that are looking for developers.
A question of the following nature: Where can one begin acquaintance with high-loaded projects for a person who has never encountered this, I speak, in particular, about myself. Maybe there are resources or books where this is written from the basics to some fundamental knowledge in simple language? I will be very glad for any recommendations, references and books. In advance, thank you very much and + to karma.
