How many pages of text can fit in 320MB RAM if the page contains 40 lines of 60 characters each (and it takes 8 bits to store one character) What would be the stack height if 100 pages are 1 cm high?

Determine the total number of characters on one page.

We multiply the given number of lines by the number of characters in one line.

40 * 60 = 2400 characters.

We find the informational amount of memory that is required for one page.

Multiply 2400 characters by 8 bits.

We get:

2400 * 8 = 19200 bits.

We translate 320 MB to kilobytes.

Since 1 MB contains 1024 kb, we get:

320 * 1024 = 327680 kb.

We translate kb into bits.

In 1 kb – 1024 bytes, and in 1 byte – 8 bits, so it will be:

327680 * 1024 * 8 = 2684354560 bits.

So the number of pages will leave:

2684354560/19200 = 139810 pages.

The height will be:

139810/100 = 1398 cm.

Answer: 1398710 pages, 1398 cm.
