1. Local area networks (LANs) allow for communication between devices within a small geographic area like a home or office while wide area networks (WANs) connect LANs across cities, countries, or globally. 2. Online public access catalogs (OPACs) provide searchable access to a library's collections through bibliographic descriptions including author, title, publisher, and call number. 3. Search engines help users find relevant information on the internet through keyword searches, with some employing web crawlers to scan content while others aggregate results from multiple sources.
