Ans 1.) A software copyright is used to prevent unauthorised copying of their software.
Ans 2.)hacking involves someone taking control of your computer and its files without the user's permission. This is normally done when the system is connected to the internet or any other network. The hacker tries to break the passwords to get onto the system, and if successfull will read files and steal information or try to destroy the system.
ans3.) Computers need to be protected from these attacks. One way is to use passwords, but another is to allow access to a system only through a computer that is not used for anything else; this is a firewall and should stop anyone who is not authorised gaining access. Another method is by using a secret code. This is called encryption and the files are set to have been encrypted.
