Answer Details

(a) Space occupied by the electronic book.

Given: 500 pages; 16 lines per page; 24,000 bits per line.

Step 1 - total number of bits:

\[ \text{Total bits} = 500 \times 16 \times 24000 = 192{,}000{,}000 \text{ bits} \]

Step 2 - convert bits to bytes (8 bits = 1 byte):

\[ \text{Bytes} = \dfrac{192{,}000{,}000}{8} = 24{,}000{,}000 \text{ bytes} \]

Step 3 - convert bytes to megabytes:

Using \(1\,\text{MB} = 1{,}000{,}000\) bytes:

\[ \dfrac{24{,}000{,}000}{1{,}000{,}000} = 24 \text{ MB} \]

The book therefore occupies about 24 MB. (If the binary convention \(1\,\text{MB} = 1{,}048{,}576\) bytes is used instead, the answer is \(24{,}000{,}000 \div 1{,}048{,}576 \approx 22.89\,\text{MB}\).)

(b) An example of auxiliary (secondary) storage: hard disk drive (also acceptable: flash/USB drive, CD-ROM, DVD, or magnetic tape).

(c) The two main types of computer software with examples:
