What is an Internet Service Provider (ISP)?
An Internet Service Provider, most commonly known as an ISP, is a company that provides its customers access to the internet. They operate the infrastructure that carries internet traffic from your device, through their network, and onto the internet, and then reverse the process for incoming data.
Why Do We Need Internet Service Providers (ISPs)?
Without ISPs, individuals and businesses would not have access to the World Wide Web. ISPs further provide multiple services aimed at meeting the specific needs of their users. For instance, besides enabling access to the internet, they could provide additional services such as email accounts, virtual hosting, and domain name registration.
When Do You Use Internet Service Providers (ISPs)?
ISPs are used anytime someone connects to the internet. They are there behind the scenes, facilitating your access to the online world. Whether it’s casually browsing the web, streaming videos, playing games, or conducting business – you would need an ISP to do any of these and more.
Where Are Internet Service Providers (ISPs) Located?
ISPs can be found all around the world, with major cities often hosting several competing service providers. They maintain several data centers for their server and networking equipment, and they may have points of presence (also called access points) in smaller towns and rural areas to provide service to customers throughout their coverage area.
How Do Internet Service Providers (ISPs) Work?
Internet Service Providers connect users to their network infrastructure, which is interconnected with larger, high-capacity backbone networks, and ultimately with other ISPs. Once connected, users can access services available on the internet. ISPs primarily function using a range of high-speed broadband technologies, including digital subscriber line (DSL), cable modem, fiber, wireless, satellite and broadband over powerlines (BPL).
