Yes it does. More than likely the RAM that is shown missing is allocated to
the video system (if you have onboard Video) and the Hard drive is about
right because of the following as explained by Western Digital:
Decimal vs. Binary:
For simplicity and consistency, hard drive manufacturers define a megabyte
as 1,000,000 bytes and a gigabyte as 1,000,000,000 bytes. This is a decimal
(base 10) measurement and is the industry standard. However, certain system
BIOSs, FDISK and Windows define a megabyte as 1,048,576 bytes and a gigabyte
as 1,073,741,824 bytes. Mac systems also use these values. These are binary
(base 2) measurements.
To Determine Decimal Capacity:
A decimal capacity is determined by dividing the total number of bytes, by
the number of bytes per gigabyte (1,000,000,000 using base 10).
To Determine Binary Capacity:
A binary capacity is determined by dividing the total number of bytes, by
the number of bytes per gigabyte (1,073,741,824 using base 2).
