Is NASDAQ a Tech Exchange?

Excuse me, could you please clarify for me whether NASDAQ is considered a technology exchange? I've heard it mentioned in the context of tech companies going public, but I'm not entirely sure if it specializes in that sector. Is it accurate to say that NASDAQ is primarily focused on technology stocks, or does it also include other types of securities and industries? I'd appreciate any insight you could provide to help me better understand the nature of this exchange.
