What is Operating System in Computer Technology



What is Operating System in Computer TechnologyAn Operating System is a Program/ Software which manages Computer hardware and software resources. Operating System creates an environment by which a user can access the computer hardware and software. Some of popular operating systems are DOS, OS/2, Windows, Linux, macOS etc. The most common features of Operating systems are – Process Management, Memory Management, File System Management, Device driver operation, Networking, Security and I/O Operations. The answer for What is Operating System in Computer Technology is illustrated below.

Classification of Operating System:




  1. Multi-user – In this type of operating system, two or more than two users can access the computer resources at the same time.

  2. Multiprocessing – In this type of operating system, more than one CPU is running the program simultaneously.

  3. Multitasking – It allow more than one program to run concurrently.

  4. Multithreading – It allow different part of a single program to run concurrently.

  5. Real time OS – It allows responding to current input instantly. DOS and Unix are not Real Time OS.

Types of Operating Systems:




  1. What is Single and Multi-tasking Operating System



The operating system can run only one program a time is called Single tasking System. The operating system which can run more than one program at a time is called as Multi –Tasking Operating System. In this OS time sharing of available processor is done. Ex 1. – Palm OS is best example of Single tasking OS. Ex- 2. – Microsoft Window 2000 is best example of Multi Tasking OS.



  1. What is Single and Multi-user Operating System



In Single user operating system, only one user work or utilise computer resources at one time. Example of Single user OS are Mac OS X, Some Linux and some Windows. In Multi User OS more than one user interact with the system at the same time. Example of Multi-user OS is Unix Servers- where multiple remote user access the Unix shell prompt at the same time frame.



  1. What is Distributed Operating System



The distributed operating system manages a group of computers and makes them appear to be a single computer. The networking technology gave birth to distributing computing system. Single operation is done with the help of information from more than one computer. This concept is used by large firms or organisations.



  1. What is Templated Operating System



In this operating system, it creates a virtual machine image for guest computer and this serves a source to operate multiple virtual machines.



  1. What is Embedded Operating System



This type of OS is used in machines like PDA. They are operated with a limited number of resources. An embedded operating system is a specialized OS for use in the computers built into larger systems. Example – ATMs, POS machine, Digital Camera, GPG navigation system, Digital television etc.



  1. What is Real-Time Operating System



A real-time operating system is an operating system that can process task or data in a specific period of time. A real-time operating system can be single- or multi-tasking, but when it is multitasking, it uses special scheduling algorithms so that a deterministic nature of behaviour is created. Such applications include small embedded systems, automobile engine controllers, industrial robots, spacecraft, industrial control and large-scale computing systems.

When Task Scheduler gets Infected by Malware

When Task Scheduler gets Infected by Malware

When Task Scheduler gets Infected by Malware - We are familiar with malware attacks on Computer. The hackers infect one or more files and thereby attaining full control on the System. There are millions of victims who had loosen either data or dollars in this respect. In this article we see a System file which is infected by these hackers at first stage. The System file infected by malware at first stage is Task Scheduler Engine (Taskeng.exe). The Task Scheduler Engine is a system file located in C:\Windows\System32 folder. This location is the default location for Taskeng.exe.



The Task Scheduler Engine is responsible for keeping track of tasks set to run at a time predefined by the user of the PC. As said earlier, the original location of this scheduler is C:\Windows\System32 folder. But it is suspicious if the location of scheduler gets change. If it is found in some other folder then it must be infectious. As a result, you constantly get a…

Fix Windows could not find a driver for your network adapter error


A Computer run smoothly with the coordination of Software & Hardware. In the absence of any one it will not run at all. Software being the Master utilizes each hardware attached to the System. And each hardware is operated with the help of Device Drivers installed in it. Operating System (OS) uses these device drivers to control & utilize each hardware when needed. Each hardware connected to the system must have their own Device Driver installed. A device driver is a program to initiate a hardware when required by Operating System.




Suppose, you want your PC to connect to the Network, it can only be possible when your PC has network related Device Driver. These Device Drivers are easily downloaded from Manufacturer Websites. In this article we focus on Network related problem. Suppose, your PC not obtaining Network connectivity. And each time you are getting an error message saying "Windows could not find a d…
