INSTALLING SOFTWARE'S:
                                        Most software programs require that you first install them on your computer before using them. for example, if you by Microsoft office, you need to install it on your computer before you can run any of the included programs such as MS word or MS excel. you can install software form a CD or DVD, an external hard drive, or from a networked computer.you can also install a program or software update form a file downloaded from the internet.
