<h1>What is Disk Scheduling?</h1>
<p>Disk scheduling is done by operating systems to schedule I/O requests
arriving for the disk. Disk scheduling is also known as I/O scheduling.</p>

<h2>FCFS</h2>
<p> The requests are addressed in the order they arrive in the disk queue. FCFS is the simplest
disk scheduling algorithm of all the scheduling algorithms.

<div class="box">
<div class="content">
<h2>SSTF</h2>
<p>The requests having shortest seek time are executed first. So, the seek
time of every request is calculated in advance and then they are scheduled accordingly.</p>

<h2>SCAN</h2>
<p>The disk arm moves into a particular direction and services the requests coming,
after reaching the end of disk, it reverses direction and services the request
arriving in its path.</p>

<div class="box">
<div class="content">
<h2>C-SCAN</h2>
<p>The disk arm moves in a circular fashion, that is the disk arm instead of reversing its direction goes
to the other end of the disk and starts servicing the requests from there.</p>

<h2>LOOK</h2>
<p>The disk arm in spite of going to the end of the disk goes only to the last request to be serviced in
front of the head and then reverses its direction from there only.</p>

<div class="content">
<h2>C-LOOK</h2>
<p> The disk arm in spite of reversing its direction from last request like in LOOK, instead goes to the
other end's last request. It prevents extra delay due to traversal to the end of the disk. </p>
