Tips & Best Practices
-
Remember that kilobyte/second (SI def.) measures bytes per second, while modem (1200) is bits per second
-
Use this conversion for general comparison rather than precise speed measurement
-
Keep in mind modem (1200) represents a fixed low-speed legacy rate
-
Consider the historical context when applying these conversions
-
Consult real-world modem performance separately due to variable line conditions
Limitations
-
Modem (1200) unit only represents legacy low data rates unsuitable for modern speeds
-
Kilobyte/second uses bytes while modem (1200) is based on bits per second, requiring careful interpretation
-
Actual modem speeds varied depending on line quality and overhead, so conversion rates are approximate
-
This tool does not reflect current high-speed data transfer technologies
-
Nominal rates do not account for error correction or protocol overhead
Frequently Asked Questions
-
What does kilobyte/second (SI def.) mean?
-
It is a data rate unit measuring 1000 bytes transmitted per second, using the decimal-based SI prefix.
-
What is a modem (1200) speed?
-
It denotes a legacy modem data rate of 1,200 bits per second, commonly used in early dial-up systems.
-
Why convert between kilobyte/second and modem (1200)?
-
To compare modern digital transfer rates with historical modem speeds and understand telecommunications evolution.
Key Terminology
-
Kilobyte/second (SI def.)
-
A data transfer rate equal to 1000 bytes per second, used for expressing throughput with decimal prefixes.
-
Modem (1200)
-
A legacy unit referring to a modem speed of approximately 1,200 bits per second used in early dial-up communications.
-
Data transfer rate
-
The speed at which data is transmitted from one point to another, commonly measured in bytes or bits per second.
