Answer:
Answer explained below
Explanation:
Yes, you can let Set-uid program that is owned by root to run your code instead of /bin/ls but it has it's own drawbacks and is actually not safe.
As you can not rely on that since some of the shells if different from the ruid drop an euid which is actually not safe.
execl("/bin/ls", "ls",(char *)0);
run this under your main program.
Since it can have a root previlege,
-$ cd /tmp/
/tmp$ sudo su
:/tmp# gcc -o system system.c
:/tmp# chmod u+s system // changing file permissions
:/tmp# exit
exit
:/tmp$ cp /bin/sh /tmp/ls
:/tmp$ ./system
<u>Steps:
</u>
1. The first thing you need to do is copy /bin/sh to /tmp.
2. After copying /bin/sh to /tmp set a new name ls but make sure your sh ->.zsh.
3. Set PATH to current directory. /tmp.
4. Compile
5. Run the program system and you can get your root previledge.
Now, with the above exmaple if you change /bin/sh soo that it points back to /bin/bash and repeat all the previous steps, you will not be able to get your root previledges.

Answer:
The reason is due to proprietary design of the Operating System (OS) which require a virtualization software to blanket or "disguise" the hardware (processor) borderlines of the computer onto which it is to be installed.
Explanation:
An Apple system that has the RISC processor and system architecture which has an operating system made entirely for the Apple system architecture
If the above Apple OS is to be installed on a windows computer, then the procedure to setup up the OS has to be the same as that used when on an Apple system, hence, due to the different processors and components of both systems, a virtualization will be be needed to be provided by a Virtual box, Parallels desktop or other virtualization software.
Answer:
A computer system works by combining input, storage space, processing, and output. For example, when we type something using a keyboard, it is known as an Input provided to the Computer. Storage Space: It is the place where our input gets stored. It is known as Computer Memory that keeps the data into it.
