Question

Сколько килобайтов составляет сообщение содержащще 12288 битов? какое наименьшее число символов должно быть в алфавите, чтобы при помощи все возможных трехбуквенных слов, состоящих из символрв данного алфавита, можно было передать не менее 9 различных сообщений? заполните предложенную схему пк

Answer 1

1) 12288 бит =12288 : 2^13 Кбайт=12288 : 8192 = 1,5 Кбайта
2)  2^3 =8<9  -  в алфавите не может быть 2 символа
     3^3 =27>9   -  если в алфавите 3 символа, то возможна передача 9 различных сообщений
3) где схема?

Answer 2

To answer your questions:

1. How many kilobytes are in a message containing 12,288 bits?

To convert bits to kilobytes, we need to divide the number of bits by 8 (since there are 8 bits in a byte) and then divide by 1,024 (since there are 1,024 bytes in a kilobyte).

So, to calculate the number of kilobytes in a message containing 12,288 bits: 12,288 bits / 8 / 1,024 = 1.5 kilobytes.

Therefore, a message containing 12,288 bits is equivalent to 1.5 kilobytes. [[1]]

2. What is the minimum number of characters that should be in an alphabet to transmit at least 9 different messages using all possible three-letter words from that alphabet?

To calculate the minimum number of characters required in an alphabet to transmit at least 9 different messages using all possible three-letter words, we need to consider the number of possible combinations.

For a three-letter word, there are n^3 possible combinations, where n is the number of characters in the alphabet.

To find the minimum number of characters required, we need to solve the equation n^3 >= 9.

Taking the cube root of both sides, we get n >= 2.08.

Since the number of characters in an alphabet must be a whole number, the minimum number of characters required in the alphabet is 3.

Therefore, an alphabet with at least 3 characters is needed to transmit at least 9 different messages using all possible three-letter words. [[2]]
