Computer architecture upgraded from 16-bit to 32-bit to 64-bit. What was the logic for skipping 48-bit? What reasoning was used to upgrade to 64-bit and not some other exponent? The following tables ...
Saw this post but couldn't comment: VM sandboxing- what happens? Is it possible to have a virtual machine (vm) without a virtual machine monitor (vmm)/hypervisor, or if you have one virtual machine ...
To give you an impression of the level of detail I'm interested, one example. I know a system call ultimately leads to a trap which lets the processor store registers, switch to supervisor mode and ...

What do the terms “asynchronous” and “synchronous” mean, with respect to the definition of an interrupt?
Quoted from http://en.wikipedia.org/wiki/Interrupt: an interrupt is an asynchronous signal indicating the need for attention or a synchronous event in software indicating the need for a change ...
I was wondering if the bits of OS, of instruction set, of CPU registers, of data bus from CPU to memory, and of address bus from CPU to memory must be consistent in some sense and how? When we cay ...
What are the differences between 32-bit and 64-bit systems? If you have used both of them, what kind of sharp differences have you experienced? Would it be a problem to use 32-bit programs on ...
