Is the Operating System?
The operating system is the core software from your computer. which perform many functions and, in very basic terms, an interface between your computer and the outside world. In the section about the hardware, the computer is described as part consisting of several components including monitor, keyboard, mouse, and other parts. The operating system provides an interface for this part using what is called a "driver". This is why sometimes when installing a new printer or other piece of hardware, the system will ask to install more software called drivers.
What to do?
What to do?
Drivers are programs written specifically to understand the operation of the device interface for it, such as printers, video cards, sound cards or CD ROM drive. This translates commands from the operating system or the user into commands understood by the computer's components with. It also translates the responses from the computer component back to the responses that can be understood by the operating system, application programs, or users. The diagram below provides a graphical representation of the interface between operating systems and computer components.
Operating System Functions
The operating system provides several other functions including:
Operating System Concerns
As mentioned earlier, an operating system is a computer program. Operating system written by human programmers make mistakes. Therefore there can be errors in the code even though there may be some testing before the product was released. Some software companies have better quality control and testing than others so you might see varying levels of quality of the operating system to operating system. Errors in the operating system causes three main types of problems:
System crashes and instability - this can happen because of software bugs in the system operating normally, although the computer programs that run on the operating system can make the system more stable or may even crash the system itself. This varies depending on the type of operating system. A system crash is the action of the clotting system becomes unresponsive and that will cause users to need to reboot.
Security flaws - Some software errors left the door open for the system to be broken into by unauthorized intruders. Because of these shortcomings are found, the unauthorized intruder can try to use it to gain illegal access to your system. Patching these flaws often will help keep your computer systems secure. How this is done will be explained later.
Sometimes errors in the operating system will cause the computer not work properly with some peripheral devices like printers.
Type of Operating System
There are many types of operating systems. The most common is the suite of Microsoft's operating system. They include from newest to oldest:
Windows XP Professional Edition - A version used by many companies on the workstation. He has the ability to become a member of a company's domain.Windows XP Home Edition - A lower cost version of Windows XP for home use only and should not be used on business. Windows 2000 - A better version of the Windows NT operating system that works well both at home and as a workstation in the business. This includes technology that allows hardware to be automatically detected and other enhancements of Windows NT.
Windows ME - An upgraded version of Windows 98 but has been historically plagued with programming errors that may be frustrating for home users.
Windows 98 - is produced in two main versions. The first version of Windows 98 interrupted by a programming error but Windows 98 Second Edition that comes out later is much better with lots of errors resolved.
Windows NT - a version of Windows intended for business offering better control over the workstation capabilities to help network administrators.
Windows 95 - The first version of Windows after Windows 3.x version offers a better interface and better library functions for the program.
There are other valuable types of operating systems not made by Microsoft. The biggest problem with this operating system lies in the fact that not many application programs written for them. But if you can get this type of application program you are looking for, one of the systems listed below can be a good choice.
Unix - A system that has existed for many years and are very stable. This key is used to be a server instead of workstation and should not be used by anyone who does not understand the system. It can be difficult to learn. Unix usually have to run a computer made by the same company that produces software.
Linux - Unix Linux is similar in operation but it is free. It also should not be used by anyone who does not understand the system and can be difficult to learn.
MacIntosh apples - the most recent version is based on Unix but has a good graphical interface so that both are stable (no crashes frequently or has a software problem as many other systems as possible) and easy to learn. One drawback of this system is that it can only run on Apple hardware is produced.
The operating system provides several other functions including:
System tools (programs) that are used to monitor computer performance, debug problems, or keep parts of the system.
A set of libraries or functions that can be used to program certain tasks primarily related to interfacing with computer system components.
A set of libraries or functions that can be used to program certain tasks primarily related to interfacing with computer system components.
The operating system makes these functions interact with other functions operate smoothly and functions is largely transparent to users.
