The document discusses the key differences between networks and the internet, system units and CPUs, and search engines and web browsers. Specifically: - A network connects computers within a local area, while the internet is a global system of interconnected networks. - A system unit houses computer components like storage, power supply, and motherboard, while a CPU is the component that processes data. - A search engine indexes web pages to help users find information, while a web browser displays web pages and allows users to view content from the internet.
