Answer:
You may nest while and do-while loops, but you may not nest for loops - False
Answer:
System calls = 500000
Explanation:
Instructions that a computer can execute = 1 billion instructions/sec
Instructions that a system call takes including the trap and context switching = 1000 instructions
When half of the CPU time is on application, n system calls can be executed in 1 second.
Therefore we'll get an equation as following.
1000 * n = 0.5 * 1000000000
n = 0.5 * 1000000000 / 1000
n = 500000
System calls = 500000
Answer: A register
Explanation:
Registers are small memory used to store data or values and supply them to the processor as and when needed. These register hold the data temporarily and hold small units of program instructions. So whenever the CPU wants to work on data they have to be made available through the registers. Even after a arithmetic operation the registers serve as buckets for holding the value.
There are different types of registers such as register A, B, C etc and these registers lie in close proximity to the CPU so that we could provide the data immediately and much faster when asked by the CPU.
Therefore we can say that registers are used to temporarily hold small units of program instructions and data immediately before, during, and after execution by the central processing unit (CPU).
True
Excel 2019 makes it easy to remove conditional formatting since users do not need to highlight data in order to remove it.
Intensity is the brightness of a color. When a color is not mixed with any black or white it is at full intensity; Also called a pure hue. You can also change the intensity of a color by adding its complimentary color.
Hope this helps
