In computer terminologies one of the most used term is Operating system. Many people use computers and even this terminology without knowing its actual meaning. In this informative article I am going to briefly look at the meaning and functions of an operating system. This information can be used by a computer user when seeking to buy an Operating System.
An operating system is simply a set of interdependent programs that enables computer hardware to communicate with computer software. These sets of programs are also called software without which a computer would not function and would be all together inoperable. Operating systems provide ground for the operation of other applications. The most popular operating systems today include: Windows operating systems such as Windows 8, Windows 7 and Windows XP and Linux such as Ubuntu.
Classification of Operating Systems.
Operating systems are classified as follows:
- Multi-processing– these are operating systems that are able to support and use more than one processor. Examples of such operating systems include: Windows 7, Windows 8 and Linux such as Ubuntu.
- Multi-tasking-these are systems that are capable of allowing multiple application to run simultaneously. Windows 8 is a good example.
- Multi-user– these are operating systems that allow more than one user to use the system at an instant good examples include Windows NT.
- Multi-threading– are operating systems that allow different parts of softwares to be used in different processes i.e. they allow softwares to run concurrently.
Looked-for features of Operating Systems.
Certain factors are put into consideration when a user wants to acquire an Operating System. These include:
- Reliability- A desirable Operating System must be completely free from errors and bugs.
- System Memory required to hold- when considering operating systems User’s prefer those that occupy lesser system memory, this is in order to allow space for productivity of the computer.
- Platform Independent- a great Operating system must be capable of running in different hardware and software combinations.
- Maintenance- good Operating Systems must be easy to maintain, that even one can carry out the maintenance by themselves.
- Efficiency- a good operating system must be good at utilising system resources such as Central Processing Unit. It must also minimize response time through reacting extra fast.
These are just examples of what one should consider before acquiring an operating system and is always placed on better ground with this information before deciding on an operating system they desire to try out. Thank you for reading this article.
