I'm starting with C development and my next job will be to implement a watch dog to control data transfer between threads in C.
What is the meaning of "watch dog", and what does it do?
A watchdog is a mechanism that periodically tests whether a process or thread is running properly. If it's not, it either restarts it or notifies an administrator, depending on the needs of the application.
The details of how you implement this will depend on the application design.

When the Kernel needs to send output to a certain peripheral, how does it know which driver to use?
The usual way is for each driver when first loaded, typically at boot time, to poll the buses it supports and look for matches between what it is designed to support and the returned signatures (vendor and device IDs), and their classes.
This is at least the way it works for the so-called plug and play peripherals.

I recently created a launchd that updates and upgrades my macports every sunday night while I'll sleep. I'm currently trying to find out if there is a way to know when macports was last updated? I'd like to know if my launchd is truly working or not.
The first thing Macports has to do when updating is synchronising the ports.
These are in /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports.
The modification date of this directory can tell you when the ports were last synchronised.

while debugging my source code my pc pointing inside the ISR function.so now what happens if power is off? please tell me answer the pc start at what location if power will come again?
When the computer restarts the PC will be reset to its initial value which points at the entrance of the BIOS. The exact value depends on the platform. Your ISR and the contents of memory will also be gone.

I have a practice room with a LAN. It is common for student to do exercises. A student create some files on a computer and I want:
- He/She can't see files of others.
- He/She can continue to work on his/her files.
I think this suits to a FTP server. But which fpt server can support over 3000 clients?
Or is there an alternative for this problem?
Thanks.
