¿Does anyone know what are these symbols?

I mean these symbols, I don't know what they are, but I think they are related to something about some companies.

BTW, I'm asking cause I have a homework where one of the things I have to do is explain what those symbols are, but they didn't explain anything, not even a hint, and I'm a computer science student, so I thought it was better to ask what are these symbols here.
