Question

объем сообщения 7,5 кбайт известно что данное сообщение содержит 7680 символов какова мощность алфавита

Answer 1

Определим количество бит на символ
i=I/k
i=(7,5*1024*8)/7680= 8 бит
Тогда количество символов в алфавите N=2^i
N=2^8= 256

Ответ: 256

Answer 2

To calculate the size of the alphabet, we need to determine the number of unique characters used in the message. Given that the message has a volume of 7.5 kilobytes (KB) and contains 7680 characters, we can find the size of the alphabet by dividing the total number of characters by the volume of the message:

Alphabet size = Total number of characters / Volume of the message

Alphabet size = 7680 characters / 7.5 KB

Before proceeding, let's convert the message volume from kilobytes to bytes since the character count is given in bytes:

1 KB = 1024 bytes

7.5 KB = 7.5 * 1024 = 7680 bytes

Now, let's continue with the calculation:

Alphabet size = 7680 characters / 7680 bytes

Alphabet size = 1

The alphabet size is 1, meaning there is only one unique character in the message. This seems unlikely for a typical text message, so there might be an issue with the provided information or calculation. Please double-check the data and the context of the message. If you provide more context or clarify any discrepancies, I'll be happy to help you further.
