ASCII text takes up 1/4 KB of memory. how many characters are in the text.

As we know from the school computer science curriculum, the encoding system specified in the condition contains 256 characters, that is, to encode one character of the text, 8 bits are required (256 = 28).

Now we need to translate the amount of memory occupied by the text, which, according to the condition of the task, is 1/4 KB, also into bits:

1 KB – this will be 1024 bytes;

1 byte – this will be 8 bits;

1/4 * 1024 * 8 = 2048.

Now we can calculate how many characters this text contains:

2048: 8 = 256.

Answer: 256.
