How do you move bios setup for a motherboard from a disc to a USB and still allow it to boot?
You cannot move the BIOS into a USB device. I think you meant the boot order/setup. To do so, enter your BIOS settings page when you switch on your computer (you have to press ESC or F8 or some other key depending on your motherboard). Then search for some option labelled something like Boot setup or boot order. There change the preference from your current boot disc (where your OS is) to the desired USB device. Note that your USB device should have a boot loader to correctly boot the OS stored on it.
What systems does an output of physical material become the input for another part of the system?
carbon cycle system
in the year 1936 konrad zuse invented the z1 computer. it was the first freely programmable computer, but it was electromechanical not electronic
What two tools can be used to remove dust from inside a computer case?
The best way to dust off a computer case is either with compressed air, or a static-free cloth of some sort. You want to avoid vacuum cleaners or furniture polish because they could damage the computer.

Chkconfig is a utility tool that is used in Linux operating systems to start or stop a program from automatically running when the system starts. You can also use the command to view or set up new services on your operating system.
What is advantage of overloading main method?
Practically speaking, there is no advantage in overloading the main method because, eitherways the main method of the current class only gets executed and not any of the parent classes, the current class might extend.
It's a conspiracy.
You will need to open the cover to your PC and there should be a jumper labelled CLEAR CMOS you need to either move the black jumper accross and back again or if it is just two pins, short the pins with something momentarily. DO THIS WITH THE COMPUTER OFF.
Failing this you can remove the battery (looks like a ten pence piece) leave it a few minutes and reinsert it. Then boot up.
What are disadvantages of semaphore?
In semaphores there is no spinning, hence no waste of resources due to no busy waiting. That is because threads intending to access the critical section are queued. And could access the priority section when the are de-queued, which is done by the semaphore implementation itself, hence, unnecessary CPU time is not spent on checking if a condition is satisfied to allow the thread to access the critical section.
Semaphores permit more than one thread to access the critical section, in contrast to alternative solution of synchronization like monitors, which follow the mutual exclusion principle strictly. Hence, semaphores allow flexible resource management.
Finally, semaphores are machine independent, as they are implemented in the machine independent code of the microkernel services.
Disadvantages
Problem 1: Programming using Semaphores makes life harder as utmost care must be taken to ensure Ps and Vs are inserted correspondingly and in the correct order so that mutual exclusion and deadlocks are prevented. In addition, it is difficult to produce a structured layout for a program as the Ps and Vs are scattered all over the place. So the modularity is lost. Semaphores are quite impractical when it comes to large scale use.
Problem 2: Semaphores involve a queue in its implementation. For a FIFO queue, there is a high probability for a priority inversion to take place wherein a high priority process which came a bit later might just have to wait when a low priority one is in the critical section. For example, consider a case when a new smoker joins and is desperate to smoke. What if the agent who handles the distribution of the ingredients follows a FIFO queue (wherein the desperate smoker is last according to FIFO) and chooses the ingredients apt for another smoker who would rather wait some more time for a next puff?
Yes, sometimes this system is useful.
Why does CLI more complicated than GUI?
Command Line Interfaces (CLI) are often considered more complicated than Graphical User Interfaces (GUI) because they require users to remember and input specific commands and syntax, which can be daunting for beginners. Unlike GUIs, which provide visual cues and intuitive navigation through icons and menus, CLIs rely solely on text-based input, making them less user-friendly. Additionally, troubleshooting and error handling can be more challenging in CLI environments, as users must interpret textual feedback without visual aids. However, many advanced users prefer CLI for its speed and flexibility once they become proficient.

Why is it you cant see your files in drive d?
The hard drive D: is usually the recovery drive for most Windows operating systems. It's best to stay away from that drive if it is.
Do some hard drive manufacturers convert ide drives to sata?
It is more common for the reverse to be true. Manufacturers will design their drives to use SATA and then modify the design to accommodate IDE. The result is a fast drive on a slow interface for people who do not have SATA ports on their computer.
When SATA was first introduced, older drive designs were converted to use SATA, but IDE was completely removed. Most 7200 RPM hard drives are just now starting to reach the limits of ATA-133 (133 MB/s). Most drives still do not take a big performance hit if used on IDE.
Is it unhealthy to spend all of ones time on a computer?
I suppose yes, because you don't get much exercise and all that. Also, staring at the screen for so long damages your eyesight.
And it becomes an addicting habit...I should know. ;D
