ISP Servers are basically what make the internet. Without ISP servers, there is not going to be an internet access, even with the complete computer package. Websites depend on ISP servers for their existence and users enjoy internet access through them.

When accessing the internet, the ISPs provide the users with the necessary information. They are provided with the username, ISP server name, and a password, which is a shared secret between the ISP and the user.

An ISP is a company that collects a fee in exchange for providing the subscriber with internet access. An access server is a large powered computer that is provided by our ISP. Their computer is especially wired to have the ability to process remote computers and give out requests to these computers. Access servers within the ISP must be properly connected for it to work successfully. ISPs themselves are connected to one another. ISP servers should be connected behind a router. A router is a device or software in a computer that determines which way to send information based on its understanding on the status of networks it is connected to.

There are three kinds of services ISPs can provide. One is a shell account. This account is entirely text based. This account is also becoming obsolete due to the fact that it is primitive and provides no security to its remote computers. Another is the ISP connection account. This account provides the user with a temporary IP address and has a full internet connection with the ISP. This is the most commonly used access server provided by our ISPs. The third is a server specific account. This account supplies the user with an ISP supplied program in his client machine which communicates with a personalized access server program via a serial line. The only advantage this account ensures over the ISP connection is that the IP address is standard every time the user accesses the internet.
