Answer: To calculate the file size, we need to consider the number of words, the length of each word in characters, and the encoding used to store the characters. Common text encodings include ASCII and UTF-8. For this calculation, I will assume that the document is encoded using UTF-8, as it is a widely used encoding that supports various characters and is more space-efficient than ASCII for non-English text.
Working:
Calculate the total number of characters in the document:
Total characters = Number of words * Word length in characters
Total characters = 256 words * 4 characters/word
Total characters = 1024 characters
Calculate the file size in bytes:
Since we are using UTF-8 encoding, each character can be represented by 1 to 4 bytes, depending on the character itself.
On average, English characters take 1 byte, while some special characters may take up to 4 bytes.
For the sake of this calculation, let's assume an average of 2 bytes per character.
File size in bytes = Total characters * Average bytes per character
File size in bytes = 1024 characters * 2 bytes/character
File size in bytes = 2048 bytes
Convert the file size to kilobytes (KB):
1 KB = 1024 bytes
File size in kilobytes (KB) = File size in bytes / 1024
File size in kilobytes (KB) = 2048 bytes / 1024
File size in kilobytes (KB) = 2 KB
So, the file size of the document is 2 kilobytes (KB) when there are 256 words in the document, and each word length is 4 characters.
