Different Types Of Operating Systems With Their Merits And Demerits

Operating system is an interface between user and application which you can run on computer system. It is a software component that is responsible for all the management of several activities of computer and helps to share the resources. It hosts various computer security software that can run on your system and handles all the operation of computer hardware. Users can access the services which are offered by operating system. You can interact with OS through graphical user interface knows as GUI and command line interface CLI. Here is an overview about different types of operating systems.

Real-time OS

It is a multitasking OS which aims to execute the real-time applications. It often used the specialized scheduling algorithms that can achieve deterministic nature of behavior. The major object of real-time OS is predictable and quick response of events.

Single-user and Multi-user OS

This type of Computer operating system allow multiple users to access a computer simultaneously. It can be classified as time sharing systems and enable multiple users to access a computer via time sharing. Single-user OS, opposed to multi-user OS are allow one user at a time.

Single-tasking and multi-tasking operating system

When you are allow to run a single drivers download program at one time, then system is grouped in single-task system category, where as the operating system allows to execute multiple tasks at one time, is called multi-tasking operating system.

Distributed Operating System

It manages a group of independent computer system or make them appear to single computer is called as distributed system. These computations are carried out on more than one system.

Embedded System

These operating systems are designed for embedded computer and operate on small machines such as PDAs. They are extremely efficient and compact by design. Moereover, these system can operate with limited number of software download resources.

Mobile OS

It is not distinct kind of OS, it is also an important in the list of operating system types. It is used to control the mobile phones and wireless communication device. Mobile multimedia formats are in-built in it. More so, it can be used in smartphones and tablet PCs.

Interactive and Batch Processing Systems

In batch processing, programs are grouped, collected and processed on later date. In this, input data are processed and collected in batches, is known as batch processing. Whereas, the interactive systems require user intervention. It cannot be executed without the presence of user. To execute any computer security software, there is need of user.

Offline and Online Processing

In online processing, the user have to contact with computer and processes which are executed under the control of central processing unit. When processes are not under the control of CPU, is called offline processing.

Things to Consider Before Choosing The Best Operating System For Your PC

Operating system (OS) is the most important among all the software installed on your PC. Performance, functioning and security of your PC majorly depend upon the OS that is installed on your PC as it plays an important role in running the computer. In the absence of an OS, the PC wouldn't be able to install programs or software, access files and internet and other information stored on the PC.

Choosing the right OS for your PC requires serious consideration. In the first instance it is not easy to select the right OS because every OS offers distinct and varied features besides the common functionalities. Some major operating systems include Linux, Unix, Microsoft, MS Windows and Mac OS X.

Considering the significance of the OS for the smooth functioning of your PC, you are recommended to spend some time for selecting the right one for your PC. Your selection of an OS should be based on various elements such as hardware requirement, cost, performance and others.

In this article we are discussing such elements at length to help you choose the right OS for your PC. Below discussed are the information using which you can make the right choice regarding the operating system:

Purpose of the PC

It is very important to determine the purpose of the PC before choosing an operating system. A PC can be used for various purposes such as business, study, entertainment, regular official job etc. So you have to choose the operating system accordingly of your using it for gaming, entertainment, word processing, multimedia editing and server etc. When you buy a new PC, it comes pre-installed with the operating system as Apple computers come preinstalled with the Mac operating system X.

Hardware components

You must know the hardware specifications of your PC when you are researching for the right operating system for your system. It helps you compare the specifications of your PC with the requirement of the particular operating system. Some of the specifications you need to consider before choosing the operating system are:

The model and version of the CPUAmount of RAMGPU and VRAMHard Disk drive spaceType of optical driveType of Internet Connection and others.

Security

Security is the prime concern for every PC user while choosing the operating system. Each OS has a different set of security protocol to offer. According to security experts, the most secure operating system today is OS X and Unix. On the contrary, Microsoft Windows and Linux are considered as less secure OSes that can be hacked easily. The security features of these OSes are not so reliable and strong so if security is your first priority then Windows or Linux is probably not the right choice. However, Microsoft has consistently releasing security updates to plug the vulnerabilities but still hackers manage to break into the security veil of the OS. So far, Mac OS X is considered the most secure OS which makes the work of hackers extremely tough.

Graphics ability

When it comes to deliver the graphics software platforms nothing can beat the performance of Apple computers. They are known for their high graphics output irrespective of their models and editions. This becomes possible because they run on a special operating system known as Macintosh OS. So if you look for high graphics output then the best option is to opt for an OS from Apple.

Furthermore, you need to be specific and sure about your requirement because no operating system is perfect and free from downsides. Every OS has positives and negatives so you have to prioritize your requirements such as security, graphics, purpose, hardware specifications etc and select accordingly.
