About Bit per second (bps)
A bit per second (bps) is the base unit of data transfer rate, representing one binary digit transmitted every second. It is the foundation from which all larger bandwidth units are built. In practice, raw bps figures are useful only for extremely low-speed links — early telegraph systems, narrowband IoT sensors, and some serial control lines operate at tens to thousands of bps. Modern connections are described in kbps, Mbps, or Gbps, making raw bps a reference unit rather than a practical measurement for everyday networking.
Early Morse code telegraph lines transmitted at roughly 10–50 bps. Modern IoT sensors on LoRaWAN networks communicate at 250–50,000 bps.
About Mebibit per second (Mibps)
A mebibit per second (Mibps) equals 1,048,576 bits per second — the binary IEC equivalent of megabit per second. It is approximately 4.9% larger than 1 Mbps. Mibps appears in network performance specifications written to IEC standards, and in operating system tools on Linux and some Unix variants that apply binary prefixes strictly. When a Linux system reports "ethtool: speed 100MiB/s", this distinction from 100 MB/s (decimal) matters in precise bandwidth budgeting.
A 100 Mibps figure represents 104.86 Mbps in decimal — about 5% more data. Network engineers use Mibps when exact binary calculations are required for buffer sizing.
Bit per second – Frequently Asked Questions
Why is a bit the smallest unit of data transfer?
A bit represents a single binary choice — 0 or 1 — which is the fundamental quantum of digital information. Every larger unit (byte, kilobit, megabit) is just a multiple of bits. You cannot meaningfully subdivide a binary digit, so bps is the floor of data rate measurement.
What modern devices still operate at bits per second?
LoRaWAN IoT sensors, some RFID readers, and legacy serial ports (RS-232 at 300–9600 baud) still deal in raw bps ranges. Satellites communicating with deep-space probes also use very low bps — NASA's Voyager 1 transmits at about 160 bps from interstellar space.
Is baud the same as bits per second?
Not exactly. Baud measures symbol changes per second, while bps measures bits per second. If each symbol encodes one bit, they are equal. But modern modems encode multiple bits per symbol — a 2400-baud modem using 16-QAM transmits 9600 bps because each symbol carries 4 bits.
How many bits per second does a human speaking convey?
Research suggests human speech carries about 39 bits per second of actual information content, regardless of language. Italian speakers talk faster but convey less information per syllable than Japanese speakers, balancing out to roughly the same bps across all studied languages.
Why did early modems top out at 56,000 bps?
The 56 kbps limit came from the Shannon-Hartley theorem applied to analogue phone lines. The 3.1 kHz bandwidth of a voice telephone channel, combined with its signal-to-noise ratio, creates a theoretical ceiling near 56 kbps. FCC power regulations further capped actual downstream to 53.3 kbps.
Mebibit per second – Frequently Asked Questions
When would I encounter mebibits instead of megabits?
Mainly in Linux system tools, IEC-compliant technical specifications, and some enterprise storage documentation. The iperf3 network testing tool can report in Mibps if configured to use binary units. Most consumer-facing software and ISPs use megabits exclusively.
How do I convert Mibps to Mbps?
Multiply by 1.048576. So 100 Mibps = 104.86 Mbps. To go from Mbps to Mibps, divide by 1.048576. At small values the difference is negligible, but at gigabit scales it can mean a meaningful amount of data.
Why does Linux sometimes use binary units for networking?
Linux kernel developers historically followed IEC recommendations to use binary prefixes where applicable. Some tools like dd and rsync default to binary (MiB/s) for disk operations. However, network-facing tools like ethtool and ip still use decimal Mbps because that is what the hardware reports.
Does the 5% difference between Mibps and Mbps matter in practice?
For casual use, no. For capacity planning and SLA compliance, yes. If a contract guarantees 100 Mibps and the provider measures in Mbps, the customer might get 100 Mbps (only 95.4 Mibps) and technically be short-changed. Data center SLAs should specify which unit system applies.
Is my ISP cheating me by using megabits instead of mebibits?
No — ISPs legitimately use decimal megabits because Ethernet and fiber standards are decimal. A "100 Mbps" plan genuinely delivers 100,000,000 bits per second. The confusion arises only when comparing with binary-unit tools. ISPs are not hiding anything; the two systems just coexist awkwardly.
