Your computer spends much of its time waiting for your input. In the case of this webpage, your CPU will do some minimal work processing the code of the page & such, but all this happens in a milisecond, while it will take you several seconds to read it.
Keep in mind that modern computers are almost never completely idle. Even when your computer is seemingly doing nothing there are processes in the background doing this and that to keep your OS going and ready for your inputs. These processes are hardly taxing, and so unless youre doing something particularly math-heavy your CPU is generally about 90% idle.
don't know why my CPU usage is totally consuming by program called SYSTEM IDLE PROCESS
CPUsage is a good site, its similar to folding@home but pays you for letting them borrow your computer.
The computers "Brain" is known as the CPU (Central Proccessing Unit)
CPU stands for central processing unit. As the name implies, the CPU processes everything the computer does and handles everything that goes on in a computer. The CPU is often referred to as the brain of the computer since everything goes through the CPU first. The purpose of the CPU is to read machine language and do what it is told by it. The machine code are the directions on what the CPU should do, but the CPU is needed in order to read this code.
CPU is the "commonly known as" name of that component. Either CPU or Processor. The acronym CPU stands for "Central Processing Unit". The previous answer of "mother bored" is completely wrong for 2 reasons: 1) it is "motherboard" or "mother board" 2) the CPU is a required add-on component TO the motherboard, not the motherboard itself.
Time when your CPU(Central Processing Unit) is idle(not being used by any program).

The system idle process does not actually use any CPU time. It just merely calculates what percentage of the CPU is being used by your processes at any given time.
CPU is always working..
When the System Idle Process is running at a high percentage, it means that your computer isn't doing anything that requires much use of the CPU at that time. For example, if you are using 5% of your CPU, the System Idle Process will be using 95% of the CPU, which means that 95% of the CPU is not being used.

Simple batch system used to for long times and they occupy the CPU even when they are actually not utilizing the CPU for example while doing the I/O operations. So the programmers thought it to be great idea if some other process can use the CPU when the previous process is idle. In multiprogrammed batch systems one user can run multiple programs and which gets the CPU whenever the CPU is idle. So it speeds up the process completion.
Think that depends on the operating system. But if it's XP. Sometimes it tries to figure out how to load your programs faster. It only knows what we program it.
Idle can be a noun, though it can also be, and more often is, an adjective or a verb.
You want you computer to use 100% of your CPU. The more CPU your computer uses, the faster it is working.
