An article typed on a computer contains 8 pages, each page contains 40 lines, each line contains 64 characters. the information volume of the article is 25 Kbytes. how many bits are used to encode each character?

First, we determine the total number of lines in this article.

To do this, we multiply the known number of article pages by the number of lines per page.

We get:

8 * 40 = 320 lines.

Since 1 line contains 64 characters, the total number of characters in the article will be equal to:

320 * 64 = 20480 characters.

We translate the specified information volume of the article from KB into bits.

Since 1 KB contains 1024 bytes, and 1 byte contains 8 bits, we get:

25 * 1024 * 8 = 204900 bits.

Find the volume of one symbol.

Divide the file size by the number of characters.

204900/20480 = 10 bits.

Answer:

10 bit.
