comment Why does my 32bit ubuntu see 8GB of RAM?
All your applications still see a 4GB virtual address space (rather than a 2 exabyte virtual address space with 64 but applications) - even AFAIR the kernel itself. Only the memory manager is aware of the larger physical memory. In some ways PAE is more efficient, there is some translational overhead, but the memory overhead of 32 bit processes is less than that of 64 bit addresses, the memory needed to store a full 64 bit page table is effectively 4 times that of a 32bit page table. While multi-tasking is popular (and thus the demand for big RAM), very few applications hit the 32bit VA limit

@AlBouazizi Top will by default sort processes (the list below the banner bar) by CPU hitting M (i.e. Shift-m) will resort the list by memory usage.

comment My Ubuntu Laptop Can't Connect to a Particular Wireless Network, while Windows Laptops do
Are they on the same laptop? Perhaps the ubuntu laptop has a wireless card that doesn't support WPA2.

comment How is the capacity of a harddisk faked?
It's a file system thing, I'm sure of it. These drives aren't modified physically.

@studiohack no problem, I just wanted to point out that there could be two possible places where there is a loose connection.

comment Understanding fdisk -l
The SCSI distinction is a bit archaic, it seems that all sata drives and usb flash drives are recognized as "sdx" desptie having nothing to do with SCSI
