The '''Netwide Assembler''' ('''NASM''') is an [[Assembly language#Assembler|assembler]] and [[disassembler]] for the [[Intel]] [[x86]] architecture. It can be used to write [[16-bit]], [[32-bit]] ([[IA-32]]) and [[64-bit]] ([[x86-64]]) programs. It is considered one of the most popular assemblers for [[Linux]] and [[X86|x86 chips]].<ref>{{Cite web|url=http://www.ibm.com/developerworks/linux/library/l-gas-nasm/index.html |title=Linux assemblers: A comparison of GAS and NASM |author=Ram Narayan |website=[[IBM]] |quote=two of the most popular assemblers for Linux, GNU Assembler (GAS) and Netwide Assembler (NASM) |url-status=dead |archive-url=https://web.archive.org/web/20131003180256/http://www.ibm.com/developerworks/linux/library/l-gas-nasm/index.html |archive-date=3 October 2013}}</ref>
