System design interviews play a vital role in hiring software engineers and managers. These interviews test the ability of the candidate to solve problems under different constraints. A candidate’s performance in a system design interview is a significant factor in deciding the hire/no-hire decisions and the level assigned to the incoming candidate.

In this course, you’ll go through a miniature form of our primary course on system design: Grokking Modern System Design Interview for Engineers & Managers. This crash course aims to give you an overall gist of the system designing process using short, easy-to-digest problems. Each design problem of the course can be completed in about 15 minutes, giving you the flexibility to include them in your jam-packed schedules.

## What is a task scheduler?

A **task scheduler** is a critical component of a system for getting work done efficiently. For example, uploading a photo or a video on Facebook or Instagram consists of the following background tasks:
1. Encode the photo or video in multiple resolutions.
2. Validate the photo or video to check for #key# content monetization: Content monetization is a way of leveraging content so that a service can profit from it as users consume it. #key#, copyrights, and many more.

The successful execution of the tasks above makes the photo or video visible. It allows us to complete a large number of tasks using limited resources. 

## Distributed task scheduling
The process of deciding and assigning resources to the tasks in a timely manner is called **task scheduling**. The visual difference between an OS-level task scheduler and a datacenter-level task scheduler is shown in the following illustration:
