Bits, bytes, and the binary vs decimal confusion
A bit is the smallest unit of digital data (0 or 1). Eight bits make one byte. Hard drive manufacturers define a gigabyte as 1,000,000,000 bytes (decimal), while operating systems traditionally use binary gigabytes (1,073,741,824 bytes), now called gibibytes (GiB). This is why a "1 TB" hard drive shows as around 931 GiB in Windows.
Internet speed vs file size
Internet connection speeds are measured in megabits per second (Mbps) or gigabits per second (Gbps). File sizes are measured in megabytes (MB) or gigabytes (GB). Since there are 8 bits in a byte, a 100 Mbps connection downloads at approximately 12.5 MB per second. A 1 Gbps fibre connection can reach up to 125 MB/s.
Storage scale from bytes to exabytes
Modern storage scales from kilobytes (KB — a short text document) through megabytes (MB — a photo), gigabytes (GB — a film), terabytes (TB — a large hard drive), petabytes (PB — used by large cloud providers), exabytes (EB), and beyond. Global internet traffic is now measured in exabytes per month.
