Realtek (Realtek) was established in 1987 and is the third largest IC design company in Taiwan, China. When the early network and audio chips were independent PCI interface cards, Realtek audio and network card drivers were the most popular download search terms on the Internet at that time. Realtek's most famous products are network chips, audio chips, screen control chips and wireless ultra-wideband chips. Since the trademark of Realtek is a crab pattern, in the early days, when the network chip and sound effect chip were independent PCI interface cards, the product cost-effectiveness was quite high, and it was nicknamed "crab card" by computer enthusiasts. Notebooks are built-in Realtek company's sound card chip. At present, Realtek has established a very complete sales system all over the world.
