Assuming that the message variable contains the string "Happy holidays", the statement message.find("days"); returns a. -1b. 10c
katrin [286]

Answer:

Answer is b. 10                

Explanation:

The find() method is used to search the string for a specified value and searches the first occurrence of that value. It returns the position of that specified value. If the value is not found, this method returns -1.

Lets say we have a message variable that contains the string Happy holidays.

message = "Happy holidays"

We use the method find() to find days word from the Happy holidays string in the message variable.

The find() method will find the position of day.

If we look at the string Happy holidays we see that the word day is at the 10th position of the string.

H     1

a      2

p      3

p      4

y      5

h      6

o      7

l       8

i       9

d      10

a      11

y      12

s      13

So it is at 10th position so the statement

message.find("days")

returns 10

Which daemon manages the physical memory by moving process from physical memory to swap space when more physical memory is neede
Anastasy [175]

Answer:

Swap daemon

Explanation:

Swap daemon manages the physical memory by moving process from physical memory to swap space when more physical memory is needed. The main function of the swap daemon is to monitor processes running on a computer to determine whether or not it requires to be swapped.

The physical memory of a computer system is known as random access memory (RAM).

A random access memory (RAM) can be defined as the internal hardware memory which allows data to be read and written (changed) in a computer.Basically, a random access memory (RAM) is used for temporarily storing data such as software programs, operating system (OS),machine code and working data (data in current use) so that they are easily and rapidly accessible to the central processing unit (CPU).

Additionally, RAM is a volatile memory because any data stored in it would be lost or erased once the computer is turned off. Thus, it can only retain data while the computer is turned on and as such is considered to be a short-term memory.

There are two (2) main types of random access memory (RAM) and these are;

1. Static Random Access Memory (SRAM).

2. Dynamic Random Access Memory (DRAM).
