A real-time operating system (RTOS) is an operating system designed to serve real-time applications that process data as it comes in, typically without buffer delays. An RTOS typically has very short response times and is used in applications such as industrial automation, medical systems, and mission-critical systems. Examples of RTOSs include VxWorks, ThreadX, and FreeRTOS.

What is the difference between preemptive and non-preemptive scheduling?

Vaibhav Kothia May 26, 2023 0 Comments

Preemptive scheduling is a scheduling algorithm that allows a running process to be interrupted and replaced by another process with a higher priority. An example of this is Round Robin scheduling.

Non-preemptive scheduling is a scheduling algorithm that allows a running process to remain in the system until it completes or is blocked by some other event. An example of this is First Come First Serve scheduling.

How does Windows handle multitasking?

Vaibhav Kothia May 26, 2023 0 Comments

Windows handles multitasking by allowing multiple programs to run at the same time. Each program is allocated a certain amount of resources, such as processor time, memory, and disk space. Windows also allows users to switch between programs quickly.

For example, a user can open a web browser, a word processor, and a media player simultaneously. Each program is allocated its own resources, allowing the user to switch between them without having to close any of them. The user can also use the taskbar to switch between programs quickly.

What is the difference between a process and a thread?

Vaibhav Kothia May 26, 2023 0 Comments

A process is an instance of a program that is being executed, while a thread is a single sequence of instructions within a process.

For example, a word processor is a process that contains multiple threads, such as one thread to handle user input, another to handle formatting, and another to handle printing. Each thread can run independently of the others, allowing the process to complete tasks more quickly.
