ISPs are continued to one or more high-speed internet lines. Larger ISPs have their own high-speed leased lines, and so they are less dependent on telecommunications services and can provide amend service to their customers.

ISPs also go on thousands of servers in data centers -- the number of servers depends on their internet service area. These big data centers manage all client traffic. Multiple ISPs are likewise connected to large courage routing centers.

ISPs are grouped into the following three tiers:

Tier 1 ISPs. These ISPs have the most global reach and own enough physical network lines to deport nigh traffic on their ain. They as well negotiate with other tier 1 networks to allow gratuitous traffic to pass through to other tier one providers. Tier one ISPs typically sell network access to tier 2 ISPs.
Tier two ISPs. These ISPs have regional or national reach and are service providers that connect tier 1 and tier 3 ISPs. They accept to buy access to larger tier 1 networks, only are peers with other tier 2 ISPs. Tier 2 networks focus on consumer and commercial customers.

Fiber. Fiber internet uses fiber optic cable to transmit data to provide much faster speeds compared with cablevision or digital subscriber line (DSL). Fiber has download speeds of 250 to 1,000 Mbps and upload speeds of 250 to ane,000 Mbps. Fiber is good for online gamers and other heavy internet users.
DSL. DSL connects users to the cyberspace using a telephone line. It is widely available, but is slowly being replaced by more reliable broadband connections such as cable and fiber. DSL is slower and offers download speeds of v to 35 Mbps and upload speeds of 1 to 10 Mbps. It is a adept option for users in rural areas and those who mainly surf the web or stream Tv on only one device.
Satellite. Satellite cyberspace access works through the use of communication satellites. Ground stations relay internet data as radio waves to and from satellites that are likely in low Earth orbit and to further ground stations. Satellite is slower, with download speeds of 12 to 100 Mbps and upload speeds of 3 Mbps, but it is a skillful selection for users in remote areas.

Nearly ISPs offer a combination of these services.

ISPs may throttle, or slow down, a user's cyberspace speed in club to regulate traffic and clear upward network congestion.

ISPs take, in the past, throttled their customers' cyberspace when connecting to Netflix -- meaning the user experience on Netflix's platform is diminished due to the Internet access provider.
