NEC Corporation (日本電気株式会社, Nippon Denki Kabushiki gaisha; an acronym for the Nippon Electric Company) is a Japanese multinational information technology corporation headquartered at the NEC Supertower in Minato, Tokyo, Japan. It provides IT and network solutions, including cloud computing, artificial intelligence (AI), Internet of Things (IoT) platform, and telecommunications equipment and software to business enterprises, communications services providers and to government agencies. It is one of the five largest defense contractors in Japan.
NEC was one of the world's largest personal computer and semiconductor manufacturers from the 1980s to the 2000s, but has largely withdrawn from manufacturing since the beginning of the 21st century, having spun off its PC business to Lenovo and its semiconductor business to Renesas Electronics and Elpida Memory.
