An OS X backup utility that automatically backs up files to a dedicated drive that is always available when the computer is turned on is called a time machine.
OS X was released in 2001 and it's Apple's version ten (10) of the operating system that runs on its Macintosh computers.
A time machine is a software tool built into the Mac operating system and it is primarily designed to automatically backup user files or data onto a dedicated drive such as an external hard drive disk through a wired connection, by using a Thunderbolt or universal serial bus (USB) cable. The automatic backup can as well be done wirelessly through a network connection.
a hello world program is simply a program that prints out hello world.
for this you would need to remember to have the same number of brackets on each side and to write print. Also remember when printing to include speech marks.
