Final answer:
To store the character 'n' in ASCII encoding, one byte is required. Computer memory is also measured with multiples such as kilobytes (KB) and megabytes (MB), with one MB being equivalent to one million bytes.
Step-by-step explanation:
To store a single character such as 'n', a computer uses a measurement of memory called a byte. The number of bytes needed can vary depending on the character encoding used. In ASCII encoding, commonly used for English text, each character is represented by one byte. Therefore, for the character 'n' in ASCII, one byte is required.
When discussing larger units of computer memory, multiplicative prefixes come into play. For instance, one million bytes is defined as a megabyte (MB). Computer storage space is also referred to in kilobytes (KB), with each KB equating to 1,024 bytes.
