Both the violin and viola are played under the jaw. The viola, being the larger of the two instruments, has a playing range that reaches a perfect fifth below the violin's. The cello is played sitting down with the instrument between the knees, and its playing range reaches an octave below the viola's. The double bass is played standing or sitting on a stool, with a range that typically reaches a minor sixth, an octave or a ninth below the cello's.

A Border Crossing Card (BCC) is an identity document as well as a B1/B2 visa that allows entry into the United States by Mexican citizens. As a standalone document, the BCC allows Mexican citizens to visit the border areas of the U.S. when entering by land or sea directly from Mexico for less than 72 hours. The document also functions as a full B1/B2 visa when presented with a valid Mexican passport. Section 104 of the United States Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (IIRIRA) serves as the legal basis for the issuance of Border Crossing Cards.

In computer architecture, the combination of the CPU and main memory, to which the CPU can read or write directly using individual instructions, is considered the brain of a computer. Any transfer of information to or from the CPU/memory combo, for example by reading data from a disk drive, is considered I/O. The CPU and its supporting circuitry may provide memory-mapped I/O that is used in low-level computer programming, such as in the implementation of device drivers, or may provide access to I/O channels. An I/O algorithm is one designed to exploit locality and perform efficiently when exchanging data with a secondary storage device, such as a disk drive.
is a cpu a input or output device?
