Internet through Cable line or Satellite
Internet through Cable line or Satellite
I have read online that there are fiber cables ran through the Oceans to reach other continents in order to provide internet connection.
I have also read that internet connection is provided through Satellites somewhere in the Orbit, and there is no need to run cables from one end of the globe to another.
I am not sure which approach is used to have people in the world connect to Internet.
Any Expert to shade some lights on this ?
Thanks

There is really very little comparison. Connection speed on all the satellite services is pretty slow and limited bandwidth. Fiber is Very fast and very high bandwidth. You would have to cover the sky with satellites to even come close to the capabilities of fiber.

But why they run cables across continents ?
The cost of running fiber is less expensive than high speed cell towers, and done right, lower maintenance for fiber than cell tower maintenance.
That may change, but that the way it is today.

Connections on land used to be provided with microwave towers. But microwave connections are also limited in bandwidth and range and are relatively expensive to maintain compared to fiber. They are also subject to interference from other signals and aircraft flying thru the transmission path. The phone companies have been using fiber for at least 20 years now.
Radio and wireless communications are good for relatively short mobile paths like cell phone and police and aircraft radios. It is cheaper to connect to anything that is not mobile by using fiber. It's also much faster.
Note that cable companies like Comcast are converting most of their networks, even local ones, over to fiber to get both lower cost and much higher speed. Makes sense since TV is digital now.

The bottom line is Fiber is a lot more reliable, a lot cheaper and a whole lot faster than the other options available today for bulk ISP traffic.
Its also one of the best solutions for some private data center reliability strategies. Before I retired, we ran fiber between primary and backup geographically distributed data centers. We offered our customers multiple SLA options -- some of which included strategies that required extremely high bandwidth and reliability between two or more data centers.
Even to your home, fiber is becoming more prolific -- as bandwidth requirements are ever increasing for home entertainment.

OK if I understand how Internet works in summary..
**Companies with Websites to provisions to their Customers, Connect to their local Internet Providers.
** Internet Providers Connect to Hubs, for instance in USA , there will be 10 Hubs.
** USA Hubs then run Cables to other Hubs in other Countries or Continents.
**For local Customers, I believe they connect straight to Internet Providers , instead of the Hubs.
That's for Cable
For Satellites connections is the same, the difference is that the Hubs have mediums that connect them to Satellites ..
Is that Correct ?

The connection is correct but that does not solve the Satellite latency issue.
