Na kọmpụta, Windows Sockets API (WSA), nke e mechara mee ka ọ dị mkpirikpi Winsock, bụ interface mmemme ngwa (API) nke na-akọwa etu ngwanrọ ngwa netwọk Windows ga-esi nweta ọrụ netwọk, ọkachasị TCP/IP / IP. Ọ na-akọwa interface ọkọlọtọ n'etiti ngwa onye ahịa Windows TCP / IP (dị ka Onye ahịa FTP ma ọ bụ ihe nchọgharị weebụ) na usoro TCP / IP dị n'okpuru. Nkọwa a dabere na Berkeley sockets API eji na BSD maka nkwukọrịta n'etiti mmemme.
