Mbps or Mbit / s It is an acronym that was developed to identify the unit of one megabit per second , which is used to quantify a data flow Which 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 or information flow. For example, a radio signal is capable of propagating information always at the speed of light, beyond if 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 standard Red book of the compact disc generates a net transfer without data compression of 1.41 Mbps . The gross flow, which provides sufficient tools to detect and correct errors and provides complementary information as a control, is of 1.94 Mbps .
Erroneously or to carry out deceptive advertising it is called "mega", to generate confusion around its true value; because the storage unit What 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 equals 100 megabits (speed per second). This means that when in an Internet advertising they assure you that they offer you 100 megabytes, you can count on 100 Mbps; which would be a pretty good speed, being that what is considered an acceptable speed is 10 Mbps. To calculate the amount of Kbytes from a number in bits you can divide that number by 8192 . This allows us to affirm that the difference between the Mbps (megabit per second ) and the MBps (megabyte per second ) is in the transmission rate. The MBps is eight times higher than what is attributed to the Mbps (1 megabyte / s = 8 megabit / s ).
Another confusion to avoid is between a megabit per second (mbps ) and a mebibit per second (Mibitps ). The equivalence between both information rates is as follows: 1,000,000 bits per second equals one Mbps , while 1,048,576 bits per second equals one Mibitps .
In any case, when a provider says that it can offer you 100 "megabytes", it refers (in most cases) to the maximum speed you can achieve with its service, in terms of transferring data from your network card to the network, is an unstable speed and you can only check if you analyze daily the Internet service you have. It should also be clarified that so far the internet connections of the houses are not more than 20 Mbps speed.
Finally, to continue with the definition of "mega", we must mention, in case it has not been clear enough that an 8-bit speed would be the same as one of 1 byte , therefore if you read 3 bytes you should multiply that number by 8 to know how many bits it equals. (32 Mbps)
To close we clarify that 1 baud is the capacity of a modem converting analog information into digital data and a baud unit equals one 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 Informatic team They are usually measured in MBps: PATA 33-133 MBps , SATA 150-300 MBps , PCI 133-533 MBps , etc.
