### Bits or Bytes

Bits or Bytes
These days we always talk about MB or GB for speed and capacity. Can somebody tell me whether they refer to bits or bytes for the following items and so on?

memory capacity
disk space such as hard disk, zip, or USB etc
network speed such as Internet, Ethernet, wireless etc

### They are Bytes that are refereed to here

by In reply to Bits or Bytes

Though now days not many people see a difference between a Bite and a Byte and use the terms interchangeably.

But the reality is that a Byte is 8 Bits.

### References context

by In reply to Bits or Bytes

Almost no one refers to "bits" except when talking about data acquisition or a recording mode for an audio format. That means all references are to "bytes" A byte is usually a collection of eight bits, or in some certain cases of memory storage, nine bits are used as an extra bit is added for memory checking. An extra bit is added when the data is put into storage, this is refered to as a "parity" bit.

### B for BYTES and b for bits

by In reply to Bits or Bytes

Everything is a factor of 2.

1 bit = 1/8 byte.
A bit can be a 1 or a 0. This is not enough info to represent a set of characters, A, B, C, etc. 8 bits allows for 256 different combinations, more than enough to acomodate an alphabit and supporting symbols.
These are referenced with a lowercase "b" - Mb, Kb, b, etc.

1 byte = 8 bits (with 256 combinations). These are referenced with an uppercase B, GB, MB, KB, B, etc.

1 KB is ROUGHLY equal to 1,000 BYTES (not 1000 Bits), actual 1024 BYTES or 8192 BITS. which happens to be 2 to the power of 10 bytes.

1 MB is 1,048,576 BYTES.
1 GB is 1,073,741,824 BYTES.

### Actually 8 bits allows for 255 combinations ...

by In reply to B for BYTES and b for bit ...

To be able to count to 256 would require another bit.

### Actually........

by In reply to Actually 8 bits allows fo ...

You count the numbers 0 to 255 which is 256.

### My only regret

by In reply to Actually........

is that you got there before me

### The zero-bit has always been a Null Value ...

by In reply to Actually........

Therefore, including zero in the count-sequence, the 8-bit computer can only count to 255.

That has always been the case. :)

Just as a 16-bit computer (without an uncommitted logic array - an arithmetic accumulator) can only achieve a count of 65,535.

I hate to argue as you know!

### Thanks again!

by In reply to B for BYTES and b for bit ...

I had thought people simply use either upper case or lower case of the letter depending upon what they feel like at the time. Just like some people write km or KM for kilometre and so on. Because of this I was not too sure if they represent themselves correctly or get understood correctly.

### Bits or Bytes

by In reply to Bits or Bytes

All the previuos posts doesnot answer your question. The First 2 posts are totally wrong answers and the third explains the difference between Bits and Bytes.
Actually the capacity of Hard Disks, ZIP Drive, Floppy Drive & USB Memory stick and the amount of RAM (System Memory) is referred to in Bytes (Symbol - B) AND the connection speed of Internet, Ethernet, Modem. etc. is referred in bits (Symbol - b).
This is a STANDARD.

### The person who posted this question

by In reply to Bits or Bytes

Is the ONLY person who can decide whether or not the answers are suitable, this has sparked a healthy debate from which many of us will learn something - including you if you bother to read the answers properly.
If you dont agree with what is being said here then feel free to voice your opinion but definitely DO NOT come here stating that experienced members are wrong, you make yourself look like a pompous ***
