CIO may refer to any of the following:

1. The CIO or Chief Information Officer is a job title of the most senior executive of an organization who handles information technology and the management of computer systems. In a standard organizational hierarchy, the Chief Information Officer reports to the CEO (Chief Executive Officer), CFO (Chief Financial Officer), and COO (Chief Organizational Officer).

2. The CIO or Chief Innovation Officer is the title of an individual responsible for technological innovation within an organization, such as a business. The CIO is also known as Chief Technology Innovation Officer, CINO, or CTIO. Responsibilities include developing new ideas and managing the new ideas of other organizational members. The position of Chief Innovation Office is centrally important to an organization's technological and business strategy.

3. The CIO or Chief Investment Officer, the job title of the member of an organization who bears the primary responsibility for how the organization invests its funds and resources. The position is usually held by a member of the board of directors.

4. Concurrent Input/Output is an optional function of the JFS filesystem. When CIO is enabled on a JFS volume, files are no longer write-locked to multiple processes. Under normal circumstances, this could cause data inconsistency if more than one process tried to write to the same file at once. However, some software, such as relational databases, can perform their own data consistency checks. In these cases, enabling CIO can reduce filesystem overhead, improving overall performance.
