Explanation:
The Action Center is a feature in window 8.1 that monitors security and maintenance on your computer.It notifies you when there is an issue.Through this user can view alerts and updates about software support problem.
The answer should be B tell me if I'm wrong.
The closest line to that would be the first line:
#!/bin/bash
echo "Hello World!"
BTW, the "#!" is referred to as a she-bang. When those are the first characters executed, the (requires an absolute path) program that follows is launched, and the rest of this file is given to it as data. To run this like a program, the execute permissions need to be set ( chmod 0755 script.sh ).
Answer:RISC(reduced instruction set computer) is the computer used for low level operation by simple command splited into numerous instructions in single clock only and CISC(Complex instruction set computer) is the computer that performs the operation in single instruction.
RISC architecture has hardwired control unit,data cache unit,data path ,instruction cache and main memory as components .CISC architecture persist of control unit,micro program control memory, cache, instruction and data path and main memory.
The differences between RISC and CISC are as follows:-
- The instruction in RISC are less and and low complexes while CISC has several number of complex instruction.
- The calculation done by RISC are precise and quick whereas CISC has slightly slow calculation processing.
- The execution of RISC is faster as compared to CISC.
- RISC uses hardware component for implementation of instruction because it does not persist its own memory and CISC implements instructions using its own memory unit .
