My first computer was a Radio Shack Color Computer 3 - 6809-based, running OS-9 Level II. It could run 32 processes at once, due to bank-switching a whole 1 Meg of memory.

After that, I got an AT&T 3b2, also known as a Convergent Safari. This was a Motorola 68010-based desktop.

Then, I graduated to a NeXT black&white "slab". I bought a used SPARCStation IPC in 1995, and put NetBSD 0.9 on it. I ran NetBSD on the IPC and a SPARCStation 10 until 2002.

I've been using Linux since 1997, starting with a DEC Alpha-based UDB, and downgrading to a x86 PC in 2002.

I run Arch linux, on my server and my laptop.

comment Low level system call
@saurav1405 - you can look at the source to find out, but for Musl libc, you can look at http://git.musl-libc.org/cgit/musl/tree/src/unistd/read.c - it's in C, but it uses a macro that I trace to the file src/thread/x86_64/syscall_cp.s. The macro expands into in-line assembly. So I'm not sure what to call it: "written in assembly" or "written in C with a line or two of assembly". Probably the latter.

comment What's the difference of the Userland vs the Kernel?
@r004 - see edits. I used wireless cards, but driver software makes SATA, SCSI and IDE disks all look the same too, despite vast differences in what they can do.

Give example of minor differences and "smoothing over" them by the driver.

comment Why does fstab use UUID instead of the actual file system name?
If I answered the original question, it might be a good idea to mark it "answered" and write a new question, just so you don't collect irrelevant answers, answers that work with the original and not the modified question.
