&lt;blockquote&gt;
&lt;p&gt;&lt;strong&gt;network topology (star vs ring vs mesh)&lt;/strong&gt;&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;Network topology is the plan that shows how all the computers and devices in a network are connected — like deciding whether everyone passes notes through one person, around a circle, or directly to each other.&lt;/p&gt;
&lt;h2 id="-like-passing-notes-in-class"&gt;🧩 Like passing notes in class&lt;/h2&gt;
&lt;p&gt;Imagine your class needs to pass notes around. In a star layout, one super-organized student — the &amp;lsquo;hub&amp;rsquo; — sits in the middle: everyone gives their notes to that one person, and they deliver each note to the right desk; it works great until that student is absent, and then nobody gets anything. In a ring layout, you sit in a big circle and can only pass your note to the neighbor on your right, who passes it along until it reaches the right person — simple and tidy, but if one person leaves mid-circle the whole chain breaks. In a mesh layout, everyone in class has everyone else&amp;rsquo;s phone number and can text anyone directly without a middleman; super reliable since there&amp;rsquo;s always another path, but you need a lot of phone plans to pull it off.&lt;/p&gt;</description></item></channel></rss>
