Which function of NOS involves swapping programs and files

yaroslaw [1]

The answer is Multitasking. NOS (Network Operating System) has the ability to execute more than one program at a time. It allows different programs to operate on the CPU, effectively giving each program a virtual copy of the CPU while preventing the program from directly manipulating the hardware. The NOS switches the CPU time from one task to another in order to create the idea that several tasks are being executed at the same time, but in reality, only one program is being executed.

Convert binary number 11101111.10111 to decimal

Alekssandra [29.7K]

Answer:

$N_{10}=239.71875$

Explanation:

In order to obtain the decimal number we have to use the next formula:

$N_(10)=d*2^{(i)}\\where:\\N=real number\\d=digit\\i=position$

(The position to the right of the decimal point we will take it as negative)

Using the formula we have:

$N_{10}=(1*2^7+1*2^6+1*2^5+0*2^4+1*2^3+1*2^2+1*2^1+1*2^0+1*2^{-1}+0*2^{-2}+1*2^{-3}+1*2^{-4}+1*2^{-5})$

$N_{10}=239.71875$
