Answer 1

При использовании 32-символьного алфавита на 1 символ требуется log(2)32 = 5 бит (2^5 = 32).
На все сообщение:
256*5 бит = 256*5/8 байт = 160 байт = 160/1024 Кбайт = 0,15625 Кбайт

Answer 2

Calculating the Size of an SMS

To calculate the size of an SMS from 256 characters in a 32-character alphabet, we can use the following formula:

Size of SMS (in kilobytes) = (Number of characters / 140) * 1

The formula is derived from the fact that a standard SMS can contain up to 160 characters in the Latin alphabet and up to 70 characters in non-Latin alphabets. Since the given alphabet has 32 characters, the number of characters per SMS will be different.

Calculation

Using the given formula: Size of SMS (in kilobytes) = (256 / 140) * 1

Result

Size of SMS (in kilobytes) = (256 / 140) * 1 = 1.82857142857 kilobytes

Therefore, an SMS composed of 256 characters in a 32-character alphabet would be approximately 1.83 kilobytes in size. I hope this helps! If you have any other questions, feel free to ask.
