## What Does mbps Mean

Mbps or Mbit / s is an acronym that was developed to identify the unit of one megabit per second , which is used to quantify a data throughput that is equivalent to 1,000 kilobits per second or 1,000,000 bits per second . It is important to note that this magnitude does not constitute a speed, since the speed at which the data is transmitted has nothing to do with the flow rate or the information flow. For example, a radio signal is capable of always propagating information at the speed of light, regardless of whether it transmits a stream of 1 kb / s or 1 Mb / s .

This information rate is usually used in video applications: 32 kbps (videophone quality), 2 Mbps (VHS quality), 8 Mbps (DVD quality) or 55 Mbps (HDTV quality), for example.

In audio applications, the compact disc's Red Book standard generates a net uncompressed data transfer of 1.41 Mbps . The raw flow, which provides sufficient tools to detect and correct errors and provides complementary information for control purposes, is 1.94 Mbps .

Erroneously or to carry out misleading advertising it is called "mega", to generate confusion about its true value; because the storage unit that is called mega is the Mega Byte (MB), which is equivalent to 1024 kilobytes.
To clarify concepts, it is interesting to mention that 100 Mbps is equivalent to 100 megabits (speed per second). This means that when in an Internet advertisement they assure you that they offer you 100 "megabytes", you can count on 100 Mbps; which would be a pretty good speed, since what is considered an acceptable speed is 10 Mbps. To calculate the number of Kbytes from a number in bits , divide that number by 8192 . This allows us to affirm that the difference between Mbps ( megabit per second ) and MBps ( megabyte per second ) is in the transmission throughput. The MBps is eight times greater than that attributed to the Mbps (1 megabyte / s = 8 megabit / s ).
Another confusion to avoid is between one megabit per second ( mbps ) and one mebibit per second ( Mibitps ). The equivalence between the two information rates is as follows: 1,000,000 bits per second is equivalent to one Mbps , while 1,048,576 bits per second is equivalent to one Mibitps .
In any case, when a provider claims that it can offer you 100 "megabytes" it refers (in most cases) to the maximum speed that you can achieve with its service, in terms of data transfer from your network card to the network card. network, it is an unstable speed and you can only check if you analyze the Internet service you have on a daily basis. It should also be clarified that so far the Internet connections of the houses have not exceeded 20 Mbps speed.

Finally, to continue with the definition of "mega", we must mention, in case it was not clear enough that an 8-bit speed would be the same as a 1- byte speed , therefore if you read 3 bytes you should multiply that number times 8 to find out how many bits it equals. (32 Mbps)
To close, we clarify that 1 baud is the ability of a modem to convert analog information into digital data and a baud unit is equal to a bit (1 baud = bps) and 1024 baud units are equal to 1 Kilobyte (1024 baud = 1kbps).
It is also important to mention that the transmission interfaces between the various elements of a computer equipment are usually measured in MBps: PATA 33-133 MBps , SATA 150-300 MBps , PCI 133-533 MBps , etc.
