Final answer:
To calculate the file size of a 2000 character text file encoded in ASCII, you multiply 2000 characters by 1 byte per character and then divide by 1024 to convert to kilobytes, resulting in an estimated file size of about 1.95 kilobytes. Another character set is UTF-8.
Step-by-step explanation:
To estimate the file size of a text file with 2000 characters encoded in ASCII, one needs to understand that each ASCII character is represented by 1 byte. Therefore, if you have 2000 characters, you would have 2000 bytes. To convert bytes to kilobytes, divide the number of bytes by 1024, as there are 1024 bytes in one kilobyte.
\( 2000 \text{ bytes} \div 1024 = \approx 1.953125 \text{ kilobytes} \).
The estimated file size for the text file is therefore approximately 1.95 kilobytes.
Another character set that could be used is UTF-8, which can use more than one byte per character depending on the character being encoded.
