|
|
I was talking to my friend, once his dad told me about his new internet speed, and then he kept telling that you can't compare Bytes and Bits, and i kept telling that you could, they were just different sizes.
As far as i heard, a byte contains 8 bits, isn't that correct?
And if you have a Internet Speed of 8mbit/s, its the same as 1mbyte/s, right?

I think they are refering to this
Mbps and Mb/s
and not bit and byte thing xP

Mbps = Megabytes per second.
Mb/s = Megabits per second.
1Megabit = 125000bytes, 125 kilobytes (kB), or approximately 122 kibibytes (KiB).
Also, a byte has 2 bits, but those bits are different than the internet bits.

1MB (Megabyte) = 8 Megabits
1 Mb(Megabit) = 2^10=1024 Kb(Kilobits) or 1024/8=128 KB(Kilobytes)
1 Byte = 8 Bits
Not sure where you got those numbers from but they are completely wrong.

Never heard of a "kibibyte" before, but AIva1110 is correct... there are not 125,000 bytes in a megabit.
There are 8 bits in a byte, so yes you can compare them, it would just be a bit more difficult because one figure is 8 times higher than the other.
People's dad's usually don't know what they're talking about. They grew up without computers so they're not only uneducated from not having the internet, but they've also suffered brain damage by having fun in more harmful ways because computers weren't around.

while it's true there's 8 bits in a byte, with data transfer you have to take into account the extra protocol headers , this causes an average of 2 bits extra for each byte transfered, making it into a nice 10 bits / byte
this makes calculating the actual max speed so much easier, and most of the time actually represents what you actually get
e.g 10MBit/sec will give you max 1MByte /Sec
1MBit tends to have a max of 100KB/sec
which matches my practical upload and download (10MBit down, 1MBit up) perfectly

No, Mbps or Mb/s are both saying megabits. MBps or MB/s would be megabytes.

One Megabyte is 1,048,576 bytes.

A byte has 8 bits in any format, excluding any extra bits on top of that 8 bits for error correction or protocol headers.
