Question 1

What is bandwidth?

Accepted Answer

Maximum data transfer rate. Measured in bits per second (Mbps, Gbps).

Question 2

What bandwidth do I need for streaming?

Accepted Answer

SD: 3 Mbps. HD: 5-8 Mbps. 4K: 25 Mbps. 8K: 100+ Mbps.

Question 3

Why is my storage smaller than advertised?

Accepted Answer

Manufacturers use decimal (1 GB = 1 billion bytes). Operating systems often use binary (1 GB = 1.07 billion bytes). This ~7% difference explains 'missing' space.

Question 4

What's the difference between bits and bytes?

Accepted Answer

1 byte = 8 bits. Storage is measured in bytes (GB, TB). Network speeds are usually in bits (Mbps, Gbps). Divide Mbps by 8 to get MBps.
