Frequently Asked Questions

What’s the difference between bits and bytes?

A bit (b) is the most basic unit of digital information, representing a single binary value of either 0 or 1. A byte (B) consists of 8 bits grouped together. Internet service providers typically advertise speeds in bits per second (bps, Mbps), while file transfer rates and download speeds are often displayed in bytes per second (Bps, MBps). This is why a 100 Mbps (megabits) connection downloads at approximately 12.5 MBps (megabytes) per second — there’s an 8-fold difference between the two measurements.

Why are there both kilo/mega and kibi/mebi units?

There are two standards for measuring digital information: the decimal (SI) system and the binary (IEC) system. In the decimal system, prefixes like kilo (k) and mega (M) represent powers of 1000 (10³, 10⁶). For example, 1 kilobit = 1,000 bits and 1 megabit = 1,000,000 bits. In computing, binary-based measurements are often more natural, where units scale by powers of 2. The IEC introduced binary prefixes like kibi (Ki) and mebi (Mi) to represent powers of 1024 (2¹⁰, 2²⁰). So 1 kibibit = 1,024 bits and 1 mebibit = 1,048,576 bits. This distinction helps avoid confusion in technical contexts.

Why does my download speed not match my internet plan?

This common confusion results from the difference between how speeds are advertised versus how they’re displayed in download managers. Internet plans are typically advertised in bits per second (like 100 Mbps), while download speeds are usually shown in bytes per second (like 12.5 MBps). Since 8 bits = 1 byte, you need to divide your plan’s Mbps by 8 to get the expected MBps download speed. Additionally, you rarely achieve 100% of your maximum theoretical speed due to network overhead, congestion, server limitations, and other factors that can reduce effective throughput.

What data rates are common for different technologies?

Different technologies operate at various data transfer rates:
– Dial-up modems: 56 kbps (kilobits per second)
– Basic DSL: 1-10 Mbps (megabits per second)
– Standard home broadband: 25-100 Mbps
– Fiber optic home connections: 300-1000 Mbps (1 Gbps)
– Gigabit Ethernet: 1 Gbps (gigabit per second)
– 5G networks: 100 Mbps to 10 Gbps (depending on conditions)
– USB 3.0: Up to 5 Gbps
– USB 3.1/3.2: Up to 10-20 Gbps
– SATA III: 6 Gbps (for storage devices)
– PCIe 4.0 (single lane): 2 GBps (gigabytes per second)
– Enterprise fiber connections: 10-100 Gbps or more

How do I calculate how long a file transfer will take?

To calculate file transfer time, divide the file size by the transfer rate (making sure both use the same unit system). For example, to transfer a 1 GB (gigabyte = 8 gigabits) file on a 100 Mbps connection:
1. Convert file size to bits: 1 GB = 8 Gb (gigabits)
2. Divide by transfer rate: 8 Gb ÷ 100 Mbps = 8,000 Mb ÷ 100 Mbps = 80 seconds
Note that this is the theoretical minimum time. In practice, various factors like protocol overhead, network congestion, and disk write speeds can make transfers take 10-30% longer than the theoretical calculation.
