What could be the best objective for power supply?
When shopping for a power supply, you first need to make sure it is capable of powering all of the equipment inside your PC. Looking at the advertised wattage is not the only factor to consider. The power supply also needs to be capable of handling the amperage needed for your PC's operation. Try to choose a power supply from a company that is known for making good products. Power supplies with a high energy efficiency rating will also save you money each month on your electric bill.
What are input and output decisions in economics?
it basicly means 'BLAH BLAH BLAH!' cos it is such useless information!
What are the hardware requirements of multiprogramming operating system?
SPECIAL REQUIRMENTS OF A MULTIPROGRAMMING OS:-
(A)I/O interrupts and DMA.
=>In order to execute instructions while I/O device is busy.
(B)MEMORY management.
=>Several ready-to-run jobs must be kept in memory.So we need more memory size.
(C)MEMORY protection.
=>data and programs
A multiprogramming system requires:
- A CPU (central processing unit) supporting a user mode for application processes and a system mode which can execute privileged instructions that control devices, memory management and other parts of the hardware. It can be called system mode, privilege mode, supervisor mode or kernel mode and it is possible to have more than one of these to allow different levels of system control. Application programs requesting reads, writes and other privileged functions pass the request to the system which in system mode would verify the validity of the request, executes the request if possible or queues the request to be done later and selects a different process to run.
- DMA (direct memory access) hardware to allow fast data transfers independent of program execution.
- A Clock/timer with interrupt capability allowing system software to manage time allocation of application programs and to pause them to allow other programs to run.
- I/O device interrupt structure to interrupt running programs so that the system can process I/O device completion and other requests and then return control to the running program.
- Memory mapping hardware to give running processes there own memory address area.
- Memory protection to prevent a running program from violating the integrity of other applications already in memory and to determine when a running process is using a memory address that has been swapped out so it can be brought back in.
What is an unintended high current closed connection between two points in a circuit called?
Power Surge

What was CORE and what did they do?
To my knowledge, CORE is/was the music publishing company that was established by the Canadian rock group RUSH for the sole purpose of administering RUSH,S music publishing.
What is the current called that is delivered by a power supply?
It's called, `current`. It's rated in amps, milliamps, microamps, etc., representing a fraction of an amp.
The simple explanation is that the voltage is the `carrier`, and the current is the `power` which actually provides the energy to do the work.
What is the most electricity you can make with a magnet coil?
A coil doesn't make electricity it can however alter voltage and amperage output.
Can you add music to a cd-r that already has one song recorded on it?
If the CD has been sealed then no you can't but if it hasn't then you should be able to by dragging and dropping the file into the CD drive on My Computer. If you need any more help email me.
S/PDIF or Sony Philips Digital Interconnect Format is a standard/protocol that specifies transmission of audio signals from one device to another in digital format. Both coaxial electrical cable and an optical fiber cable can be used to carry signals in S/PDIF format. - Neeraj Sharma

Examples of hardware: CD-Rom, Graphics Card, Sound Card, Hard Drives, RAM. Hardware are the physical items that make your computer; everything within your computer case itself. Now system software are programs ran within your computer, examples are: Microsoft Office, Windows XP, MSN Messenger, Adobe Acrobat.
What is HISR and LISR in embedded systems context?
HISR: High Level ISR (Interrupt Service Routine)
LISR: Low Level ISR
What is the rating in KVA for a desktop computer?
If a device doesn't give its power rating in kVA (or VA), then it can be calculated pretty easily: (volt-amperes) VA = V (voltage) x A (maximum amperage) (kilovolt-amperes) kVA = VA (volt-amperes) / 1000
What nds r4 is the best one to buy?
If you are looking to buy an R4 for your Nintendo DS, DS Lite or DSi, i have several recommendations. The MAGIX 300X R4 costs $10-$25 brand new, and it only has a 2GB interface, but its durability is outstanding and it is not a Helvi-Trax device, so there is no security blocks on it.
