Tier Carrier

These types of internet connections are used by Internet Service

Providers (ISP) to connect to the internet backbone

They are of 3 types T1, T2 and T3.

The main difference between T-1,T-2,T-4 and T-3 internet

connections are the number of individual channels

Each individual channel, that can carry both data and voice

traffic, has a band width close to 64Kbps

Tier Connection

A T-1 line consists of 26 individual channels whereas T-3 has

672 individual channels

Therefore, if you do the mathematics for T-3 lines, we are talking

about 43Mbps or more. T-5 is up to 400Mbps.

InternetoverSatellite

Satellite connection provides uninterrupted internet connectivity.

Internet over Satellite uses a communication satellite that is on astationary position in orbit.

Due to the huge distance the data has to be transmitted, thespeed of satellite is a bit lower than Broadband types of internetconnections.

Average bandwidth at which it operates is 500Kbps

Optical Cable

Fiber-optic is the most common internet connection

It has the highest data rates compared to other types of internetconnections after internet2

It is easy to maintain

There are three types of fiber-optic internet connections and

they are the plastic optical fiber, single mode, and multimode.

Its bandwidth is 1Gbps+

Internet2

Internet2 provides the highest internet speed connectivity

It was developed by a networking consortium to meet the high-speed internet demand for research and education work

It has a speed of 100Gbps

The use of internet2 is not common
