A certain computer can be equipped with 268,435,456 bytes of memory. Why would a manufacturer choose such a peculiar number instead of a round, even number like 250,000,000

Computer system use Binary and it uses power of 2 only.

Explanation:

The reasons for equipping memory with a peculiar number instead of round or even number are as follows:

The computer system uses the power of 2 instead of the power of 10 to equipping memory and hence use a number like 250,000,000 is not possible. The computer systems work on the memory where 1 MB or 1 megabyte shows as 1024 kb or 1,048,576 bytes. In computer system memory capacity is always some multiply of 1024 bytes. Hence, 268,435,456 bytes of memory shows 256 MB of memory.
