let's separate these into two categories simple ones

CPU RAM hard drive and graphics cards these are the fundamental parts of any desktop computer it may seem daunting at first so let's separate these into two categories simple ones and the more complex ones for starters let's look at the case the case is nothing more than a big hunk of plastic that houses everything else some of them have more or less physical space some of them have different parts where you can put screws in or this or that but at the end of the day all the case really does is provide a nice enclosed system for everything else next up we have the power supply this part of your computer almost always located.

On the bottom is the part that plugs into the wall and provides all of the other parts with the electricity needed to do their thing you can think of it as an extremely advanced AC adapter the last of the simple parts to mention is the motherboard the motherboard is a wide and flat circuit board that all of the other components plug into it's the par…

Welcome we'll start with class eight science the second chapter

Welcome we'll start with class eight science the second chapter where we will talk about microorganisms now let's first understand the term microorganisms so let's say when we talk about organisms all of us are included in the category of organism the word micro as soon as it comes that means small ah very small I would say rather which cannot be seen by unaided eyes so I need some kind of aid to help see those objects.

 So what could be those aids those could be lets say a magnifying glass so if it's a kind of little bigger object I can use a magnifying glass to view it in cases where the microorganism is really really small what we use is a microscope so this is an example of microscope you have a mirror here you place your object here that you want to see on a slide and with this which is known as the lens you have different powers of the lens you can see zoom out and see from here what actually the organism looks like.

 So this is what we understand by microorgani…
