ISPThe Internet brings with it a remarkable change in the way we communicate and not to mention enormous opportunities. No matter how you describe the phenomenon, it has now entered the mainstream of the communications industry. At the forefront of this dramatic entry into the communications industry were Internet Service Providers (ISPs). Tens of thousands of these businesses already exist around the world. Some ISPs are small businesses that serve a local neighborhood. Other ISPs are very large enterprises, changing hands for sums in the hundreds of millions of dollars. Just like the commercial sector, not all businesses survive. So, with this in mind, past, present and future issues are important aspects that should be carefully examined to ensure a stable company. Additionally, building an ISP can be done in many ways, but some technological and business issues present can be beneficial to the ISP. The Internet is undoubtedly the unintended result of the initial research goals articulated by the Advanced Research Projects Agency of the United States. State Department of Defense in the late 1960s. The Internet is now a network that, as of January 1998, serves approximately 30 million connected computers. These systems are served by over 30,000 Internet Service Providers worldwide, operating predominantly on a commercial basis as service providers. The activity of ISPs now includes the participation of telephone service providers from all over the world, as well as the active participation of medium-sized and small businesses. Their services range from mass marketing of easy-to-use products to intensive operations providing specialized levels of service to more localized Internet marketplaces. The exponential growth of the Internet continues. Annual growth rates in the number of connected host systems range from 63% per year in Europe, to 90% in North America, and 111% in Africa. The number of users, the number of connected systems, and the volume of Internet traffic continue to show exponential growth. This growth likely won't continue in the long term, but at this point new applications continue to power the Internet, such as e-commerce. A number of factors often prevent the final step towards commercializing the academic and research network..
