An ISP can be commercial, non –profit, community-based or privately owned. Data can be transmitted using several means like dial-up, DSL Modem, high speed interconnects, cable modem or wireless.
A customer can connect and communicate with an ISP with the help of emails, telephone, online chat support system etc. The service combination varies across all service. The customer used to pay a subscription fee to ISPs for Internet Access. The ISP’s are interlinked to each other mostly at internet access point and pay other larger ISPs for Internet access.

Multiple PoP’s have separate connections to an ISP. There are various forms of ISP like Free ISP that provides internet service free of charge; Wireless ISP which is based upon wireless networking and Virtual ISP that buy services from another ISP and allow its customer to utilize internet infrastructure.
