The term 'COMPUTER INSERT' can be broken down into three separate words, DISC (4 letters), DISK (4 letters), and CDROM (5 letters). A DISC is a round, flat object that is used to store data. It is usually made of plastic and has a metal coating on one side. A DISK is similar to a DISC, but it is usually made of metal and has a magnetic coating on one side. A CDROM is an optical storage device that uses laser technology to read and write data. It is commonly used for storing music, movies, and other digital media.
