Question 1

What is fiber optic internet?

Accepted Answer

Fiber optic internet transmits data as pulses of light through glass strands, delivering gigabit speeds with very low latency and minimal signal loss compared to copper cable.

Question 2

What is BDIX?

Accepted Answer

BDIX (Bangladesh Internet Exchange) lets local ISPs exchange traffic directly inside Bangladesh, which means Bangladeshi websites, FTP servers, and Live TV stream much faster than going through overseas routes.

Question 3

How much speed do I need?

Accepted Answer

Light browsing 1-2 devices: 20 Mbps. HD streaming 3-5 devices: 40-80 Mbps. 4K + gaming: 150-300 Mbps. Heavy households / power users: 500 Mbps+.

Question 4

What is symmetric internet?

Accepted Answer

Symmetric means upload speed equals download speed. Most RoarZone plans offer 50% symmetric upload, and enterprise leased lines are fully symmetric — important for content creators and remote workers.

Question 5

What is Lancache?

Accepted Answer

Lancache is a local server that caches game/streaming downloads (Steam, Epic, Origin, Battle.net). Re-downloads and updates come from the local cache instead of the internet — much faster.
