That is BS... however, the 64bit version of WinXP and Vista can address 18,446,744 Terabytes...or, 18 Zettabytes. So, if the laptop is running a 64bit OS then that argument is invalid.
Some more info for anyone that cares:
The reason that 32bit OS's can only address 4gb is because the largest number that can be represented by 32bits is 2^32, which is 4,294,967,296 bytes. Divide by 1024 to get 4,194,304 kilobytes. Divide by 1024 again to get 4,096 Megabytes. Divide by 1024 one more time and you get exactly 4 Gigabytes.
You may be asking why I started at bytes instead of bits but thats because the smallest addressable unit of memory is 1 byte, individual bits cannot be addressed (read/written) by themselves, which is a result of the design of the modern IO controllers
A 64bit OS can address 2^64, which equals 18,446,744,073,709,551,616 bytes.... 18.446 Zettabytes.
Here is the full sequence of the naming convention:
Bytes, Kilobytes, Megabytes, Gigabytes, Terabytes, Petabytes, Exabytes, Zettabytes, Yottabytes, Harpibytes, Grouchibytes, Zeppibytes, Gummibytes, Chicibytes.
Anything larger than a Chicibyte has not been named yet and probably won't have to be for thousands of years. |
