Data.ByteString is a simple strict sequence of bytes (as Word8). That<br>
means the whole thing is in memory at once in one big block.<br>
<br>
Data.ByteString.Char8 provides the same type as Data.ByteString but the<br>
operations are in terms of 8-bit Chars. This is for use in files and<br>
protocols that contain ASCII as a subset. This is particularly useful<br>
for protocols containing mixed text and binary content. It should not be<br>
used instead of proper Unicode.<br>
<br>
<br>
Data.ByteString.Lazy is a different representation. As the name<br>
suggests, it's lazy like a lazy list. So like a list the whole thing<br>
does not need to be in memory if it can be processed incrementally. It<br>
supports lazy IO, like getContents does for String. It is particularly<br>
useful for handling long or unbounded streams of data in a pure style.<br>
<br>
Data.ByteString.Lazy.Char8 is the Char8 equivalent.<br>
