Answer:
3,265,920 unique ID exist.
Explanation:
The nine digits are from 0 to 9, there are ten bits from 0 -9,
0, 1, 2, 3, 4, 5, 6, 7, 8, 9
The first is select from the highest bit (9), and the second is selected at random from 0 - 9, the third bit to the last must be unique and different from each other;
number of unique IDs = 9 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2
Multiplying the nine bits of unique IDs = 3,265,920.

Answer:
1.the program is moved from secondary storage to memory.
Explanation:
Secondary storage media generally have greater storage capacity than RAM (random access memory), for this reason the data and program are stored there.
but ram memories are much faster, for example, a solid state disk (SSD) with SATA III connection can have read and write speeds of approximately 500 MB/s, while a DDR III RAM can have speeds between 12 and 18 GB/S, that is, more than 20 times faster.
So that the flow of data at the time of running a program is optimal, the data from the secondary storage unit is copied to the RAM and this ensures that the speed at which the programs run is at least 20 times faster, and our processes run better.
In terms of websites, there's a service called cloud flare which can prevent DDOS attacks in websites. Other applications you would have to look up. Hopefully this helps!
If your on a computer then you can download a screenshot app if you dont already have one and all you do is simply screen shot your whole screen .and if it is on a tablet or phone there should be a screenshot button right there.
