Question

1.)Переведите:5Кб_байт_бит;213бит_байт_Кб;1,5Гб_Мб_бит;512Кб_байт_бит2)Информационное сообщение объёмом 450 битов состоит из 150 символов.Каков информационный вес каждого символа?

Answer 1

1)
5 Кб = 5120 байт = 40960 бит
213 бит = 26.625 байт = 0.2080078125 бит
1,5 Гб = 1536 Мб = 12884901888 бит
512 Кб = 524288 байт = 4194304 бит
2) 450\150=3 бита

Answer 2

Conversion of Units:

1) To convert between different units of data storage, we can use the following conversion factors:

- 1 kilobyte (KB) = 8,000 bits - 1 byte = 8 bits - 1 megabyte (MB) = 1,024 kilobytes - 1 gigabyte (GB) = 1,024 megabytes

Using these conversion factors, we can calculate the conversions:

- 5 kilobytes (KB) to bytes (B): - 1 kilobyte (KB) = 1,024 bytes (B) - Therefore, 5 kilobytes (KB) = 5 * 1,024 bytes (B) = 5,120 bytes (B) [[1]].

- 213 bits to bytes (B): - 1 byte (B) = 8 bits - Therefore, 213 bits = 213 / 8 bytes (B) = 26.625 bytes (B) [[2]].

- 1.5 gigabytes (GB) to megabytes (MB) and bits: - 1 gigabyte (GB) = 1,024 megabytes (MB) - 1 megabyte (MB) = 8,000 kilobits (Kb) - Therefore, 1.5 gigabytes (GB) = 1.5 * 1,024 megabytes (MB) = 1,536 megabytes (MB) - 1,536 megabytes (MB) = 1,536 * 8,000 kilobits (Kb) = 12,288,000 kilobits (Kb) [[3]].

- 512 kilobytes (KB) to bytes (B) and bits: - 1 kilobyte (KB) = 1,024 bytes (B) - 1 byte (B) = 8 bits - Therefore, 512 kilobytes (KB) = 512 * 1,024 bytes (B) = 524,288 bytes (B) - 524,288 bytes (B) = 524,288 * 8 bits = 4,194,304 bits [[4]].

Information Weight of Each Symbol:

2) To calculate the information weight of each symbol in an information message, we need to know the total number of bits in the message and the total number of symbols.

Given that the information message has a volume of 450 bits and consists of 150 symbols, we can calculate the information weight of each symbol as follows:

- Information weight of each symbol = Total number of bits / Total number of symbols - Information weight of each symbol = 450 bits / 150 symbols = 3 bits per symbol

Therefore, the information weight of each symbol in the message is 3 bits per symbol [[5]].
