Most new computers that are sold these days have an operating system installed. But what a good amount of new pc users do not notice, is that without an operating system, that computer would be a simple shell, useless for the most part. A pc missing a computers operating system would not display anything more than a bunch of perplexing text messages that describe the computer’s boot process.
Earlier pcs did not have an operating system and if you’ve got experience with the computers of the early eighties, you may remember that nearly all of them did not even have a hard drive. These old pcs booted an MS-DOS kind operating system from drivers saved onto a floppy disk. To make matters worse, in order to run programs, you needed to remove the boot floppy and then insert a new floppy that contained the software application. The floppy not only stored the program such as a (word processor, spreadsheet, etc.), it also stored the drivers that the program needed to connect with the computer’s hardware. As you can imagine, the awkward process of switching from floppy to floppy prompted the birth of the operating system.
An operating system is, for the most part, a software program that controls how the pc’s hardware and software works. It manages the activity of each component and then displays that activity as a user-friendly interface known as a Graphical User Interface(GUI). It keeps track of where things exist on a computer’s hard drive as well. But perhaps the most importantly for the end-user, the operating system is accountable for translating commands issued with a keyboard,mouse or any other user input device and translate it into computer language known as binary code (010110101 stuff) that will communicate with a set of speakers, a printer, a scanner and so on.
With an operating system installed onto a pc’s hard drive, users no longer must boot a computer along with a floppy disk, nor do they have to run programs from a floppy disk. All of the drivers of a program are stored onto the pc and used whenever a application is started.
Apple’s Macintosh computer was among the first of a couple systems to institute a user-to-hardware relationship through a user-friendly interface. Nowadays, we| have quite a few operating systems available, many of them free. Some of the more well-liked ones are Windows Vista, Mac OS X, IBM, Unix, Linux among others. But even still, operating systems have extended onto to non-computer devices such as game consoles, portable music players, and PDAs. Regardless of the device, the operating system installed onto it serves the identical purpose across the board, to enable user-to-hardware communication.
These days, you don’t often need to concern yourself with how Computer Operating Systems function, because for the most part, they have become very hands off. That said, it is always a good idea to become familiar with your Operating System, so that if something were to go wrong, you will be better capable at resolving your PC Operating System Issues. As you have familiarized yourself with this cool technology, you’ll find that it is easier to troubleshoot your own PC issues, and for that reason save money.
