A sound card (also known as an audio card) is an internal computer expansion card that facilitates economical input and output of audio signals to and from a computer under control of computer programs. The term sound card is also applied to external audio interfaces that use software to generate sound, as opposed to using hardware inside the PC. Typical uses of sound cards include providing the audio component for multimedia applications such as music composition, editing video or audio, presentation, education and entertainment (games) and video projection.
Sound functionality can also be integrated onto the motherboard, using components similar to plug-in cards. The best plug-in cards, which use better and more expensive components, can achieve higher quality than integrated sound. The integrated sound system is often still referred to as a "sound card". Sound processing hardware is also present on modern video cards with HDMI to output sound along with the video using that connector, previously they used a SPDIF connection to the motherboard or sound card.
"Choose the right" is a saying or motto among members of The Church of Jesus Christ of Latter-day Saints (LDS Church) that is taught to children and used by members of the church as a reminder to make choices that will help an individual to live righteously. The phrase is taken from an LDS hymn which has that title.
The letters CTR, a reference to this phrase, are incorporated into a shield logo designed by Helen Alldredge, Margery Cannon and Lurene Wilkinson who were Primary General Board members in the 1960s. In 1970, a church committee headed by Naomi W. Randall recommended that the shield be incorporated into official church material. Since then, both the phrase and symbol have been used in religious educational materials for LDS youth of Primary age. The symbol is also used in LDS culture by members of all ages, both as a reminder of the motto, as well as an indicator of religious affiliation. The CTR initials, displayed on the shield and in other forms, can be seen mainly on CTR rings as well as other types of jewelry, tee shirts, bookmarks and stationery.
