Operating systems most often are a part of a computer’s hardware; that is, the stuff that is already loaded onto the computer when it is purchased. Without an operating system, even the most sophisticated of computers is basically just a box.
It is operating systems that allow users to take advantage of downloads that are available on the Internet or from other sources. These downloads give access to other services such as capturing and printing photos, transferring music from computers to personal listening devices, file sharing, and other functions.
There are several different operating systems, and some users have their distinct favorites. Each time they purchase or otherwise procure new computers, the hardware in them will have their preferred operating system. When faced with a computer that’s run by an unfamiliar operating system, the user may have difficulty doing certain tasks, although the majority of operating systems are very user-friendly.
Sometimes, operating systems preferences are predicated by specific computer uses. For example, someone whose job requires desktop publishing might have to use particular types of operating systems.
Other users make it a point to obtain at least a working knowledge of different kinds of operating systems. They may even go so far as to have two or more computers, each with different operating systems, just so they can become familiar with all of them and work equally well on all of them.
Some users may also avail themselves of computers with different operating systems so that they can access downloads they need. Some downloads require that computers have certain capabilities. Having access to two or more different operating systems increases your access to downloads.
Like pretty much everything else, deciding which operating systems to use is a matter of personal choice. There are no “right” or “wrong” choices, as long as you make an informed decision.
