Typically when you purchase a computer or electronic device, there will be programs and applications installed on it. While these programs may be very useful and what you need, there are probably other computer programs you would like to install.
Installing programs and applications on your computer’s hard drive involves putting program files onto your computer. These program files will make the program ready for execution by the computer when you tell the computer you want to open the program. What actually happens when you install a program is that the code for the program is placed on your computer’s hard drive in files that are ready to be executed.
