You should avoid deleting the unknown files to store your personal files and folders because if you delete that files it may be critical position with computer.
Answer: Using secure copy 'SCP' we can copy all files from a remote directory into local folder. It also replaces existing files.
Explanation:
This is illustrated as follows:
scp -r [email protected]:/path/to/server/source/folder/ .
-r is recursively copy all files
username is your username in your system
IP, here you cab specify the IP or type the website such as www.google.com
Then we specify the path, complete path
"." dot here refers the current directory. To copy the contents in the current directory.
White hat hackers use their capabilities to uncover security failings to help safeguard organizations from dangerous hackers. They can sometimes be paid employees or contractors working for companies as security specialists who attempt to find gaps in security.

Explanation:
CPI means Clock cycle per Instruction
given Clock rate 600 MHz then clock time is Cー 1.67nSec clockrate 600M
Execution time is given by following Formula.
Execution Time(CPU time) = CPI*Instruction Count * clock time = 
a)
for system A CPU time is 1.3 * 100, 000 600 106
= 216.67 micro sec.
b)
for system B CPU time is 
= 333.33 micro sec
c) Since the system B is slower than system A, So the system A executes the given program in less time
Hence take CPU execution time of system B as CPU time of System A.
therefore
216.67 micro = =
Instructions = 216.67*750/2.5
= 65001
hence 65001 instruction are needed for executing program By system B. to complete the program as fast as system A
