A network connects two or more computers allowing them to communicate and share resources. Common networks include home, school, and office networks. A network uses networking equipment like network interface cards, cables, switches, and routers. Larger networks are made up of interconnected local area networks (LANs) to form wide area networks (WANs) that can span buildings or regions. Common devices on a network include clients that receive services from servers which provide shared resources like printing, file storage, email, and webpages. Networks connect to the internet through routers and internet service providers.
