Question

Первоначально записанного в 16-битном коде Unicode, в 8-битную кодировку КОИ-8. При этом информационное сообщение уменьшилось на 480 бит. Какова длина сообщения в символах?

Answer 1

Пусть K - количество символов в сообщении.
Тогда 16*K - 8*K = 480, K = 60

Answer 2

Calculating the Length of the Message in Characters

To calculate the length of the message in characters after converting the initially recorded 16-bit Unicode code to an 8-bit KOI-8 encoding and reducing the information message by 480 bits, we can use the following steps:

1. Initial Information: - Initially recorded in 16-bit Unicode code. - Converted to 8-bit KOI-8 encoding. - Information message reduced by 480 bits.

2. Calculating the Length: - To calculate the length of the message in characters, we can use the formula: ``` Length of message (in characters) = (Reduced bits / Bits per character) ```

3. Applying the Formula: - Given that the information message was reduced by 480 bits, we need to determine the number of characters in the message.

- Using the formula: ``` Length of message (in characters) = (480 / Bits per character) ```

- To find the value of "Bits per character," we can refer to the standard bit per character for the specific encoding.

Conclusion

The length of the message in characters after converting the initially recorded 16-bit Unicode code to an 8-bit KOI-8 encoding and reducing the information message by 480 bits can be calculated using the formula mentioned above.
