Motherboards, CPUs, and RAM, oh my! In the twenty-first century, libraries are dependent on these easily confused or misidentified hardware components and terminologies. Modern information systems—ranging from library OPACs to electronic research databases—all require machines that have a motherboard beneath their shiny plastic hoods. Library skills, including Boolean searching and complex taxonomic classification, also rely on computer technology. Librarians regularly make expensive decisions about the hardware in their facilities, but it is easy to get tongue-tied by the acronyms and technical names for the hardware in these machines. A basic grasp of hardware components has the potential to greatly enhance our awareness of our information systems. Libraries can also save money by making informed technology decisions. It’s time we met our motherboards.
