How many characters can you store with 1 byte

Question

1 byte   8 bits    So  does this mean 1 byte can only hold one character  E g     16  uses 2 bytes    9  uses 1 byte    a  uses 1 byte   b  uses 1 byte    and if tiny int has range of 0-255  does this mean it can be stored with 255 char   what is storage of   1  tiny int  1  2  tiny int  2     what will be the range 0-10

Yes  1 byte does encode a character  inc spaces etc  from the ASCII set   However in data units assigned to character encoding it can and often requires in practice up to 4 bytes  This is because English is not the only character set  And even in English documents other languages and characters are often represented  The numbers of these are very many and there are very many other encoding sets  which you may have heard of e g  BIG-5  UTF-8  UTF-32  Most computers now allow for these uses and ensure the least amount of garbled text  which usually means a missing encoding set   4 bytes is enough to cover these possible encodings  I byte per character does not allow for this and in use it is larger often 4 bytes per possible character for all encodings  not just ASCII  The final character may only need a byte to function or be represented on screen  but requires 4 bytes to be located in the rather vast global encoding  works

1 byte may hold 1 character  For Example   Refer Ascii values for each character  amp  convert into binary   This is how it works    value 255 is stored as  11111111  base 2   Visit this link for knowing more about binary conversion  http   acc6 its brooklyn cuny edu  gurwitz core5 nav2tool html  Size of Tiny Int   1 Byte   -128 to 127   Int   4 Bytes  -2147483648 to 2147483647

The syntax of TINYINT data type is TINYINT M     where M indicates the maximum display width  used only if your MySQL client supports it       The  m  indicates the column width in SELECT statements  however  it   doesn t control the accepted range of numbers for that field       A TINYINT is an 8-bit integer value  a BIT field can store between 1 bit  BIT 1   and 64  bits  BIT 64   For a boolean values  BIT 1  is pretty common    TINYINT
