Answer:
The RAM capacity expressed in bytes is
512 million bytes
Explanation:
a) Data and Calculations:
RAM contains 256m words
Each word = 16 bits
1 bit = 0.125 byte
This means that each word will have 2 (16 * 0.125) bytes
Therefore, the RAM contains 256m * 2 = 512 million bytes
b) A bit is 0.125 bytes and a byte is eight times bigger than a bit. This implies that there are eight megabits in every megabyte, and one gigabyte is eight times bigger than one gigabit. The 512 million bytes above are about 488.3 gigabytes, since 1 gigabyte equals 1,024 megabytes or 1,046,576 kilobytes.
