Internet providers, also known as Internet Service Providers (ISPs), are companies that offer access to the Internet for homes and businesses. They connect users to the web through various technologies, including fiber optics, cable, and DSL (Digital Subscriber Line). ISPs may provide additional services like email accounts, web hosting, and security features. There are different types of ISPs, including national and regional providers. Some well-known ISPs include Comcast, AT&T, and Verizon. Users typically choose an ISP based on factors like speed, reliability, customer service, and pricing.
