Let's start with the computer case. This is the metal enclosure that contains many of the other hardware components. It comes in various shapes and sizes, but a typical tower model is between 15-25 inches high. Want to know what's inside? Okay, go get a screwdriver and let's open it up. Seriously, if you are really into computers, the best way to learn is to actually get hands-on. To save us some time, however, have a look at this desktop computer case. A computer enthusiast replaced the metal side panel with a transparent one, so we can have a look inside.

Although that photo looks pretty cool, it is a bit hard to recognize the individual components, especially.with all the connecting wires running through it. This figure shows a more schematic version of a desktop computer, which makes it easier to point out the essential hardware components.
The various components of a computer case
computer tower schematic.The computer case contains a power supply unit to convert general-purpose electricity to direct current for the other components. The most critical component is the motherboard a plastic board on which several essential components are mounted. This includes the central processing unit, or CPU, the main memory and expansions slots for other hardware components. The internal hard disk drive serves as the mass storage device for data files and software applications. An optical disk drive makes it possible to read from and write CDs and DVDs. Other hardware components typically found inside the computer case (but not shown in the figure) are a sound card, a video card, and a cooling mechanism, such as a fan.
it may seem like you need to buy some expensive gear to make good videos but in reality it's not the case if you're just starting a youtube channel or want to post quick videos on social media all you really need is a smartphone and not specifically an expensive one i will show you the five best budget smartphones with a good camera for shooting photos and videos let's go hi my name is arthur and welcome to the movavi vlog and number five is the oppo a53 that costs around 150 us dollars the 13 megapixel camera with f 2.2 aperture and the 16 megapixel front facing camera with f 2.0 aperture the rest are the 2 megapixel depth sensor and the 2 megapixel macro sensor there's the ai tag built into it ai beautification as they call it and the flashlight of course and here is my opinion based on the test footage that i saw on youtube the photos are looking really good for the camera at this price a good amount of details in the image it's not oversaturated unlike samsung smartphones for example the overall color temperature is drawn closer to colder shades if we crop the image we'll start noticing the areas where the picture is washed out and a little noisy and this is in daylight i like the dynamic range on this camera and the ability to turn on the hdr mode is also very nice but nothing too exciting this mode just brings up the shadows a little now let's move to the close-up shots i was expecting the autofocus to work better but in reality it's not stable and you need to pay a decent amount of effort to catch the correct focus point i was very surprised by its portrait mode i expected to see worse results with this phone skin tones are very close to reality face detection and edge detection also works well and it's very surprising because even iphones are not perfect at this low light filming is possible but the scene needs to be evenly lit with light the more shadows you have in the image the more noise you're gonna get i can quickly call this footage unusable even the f 2.2 aperture doesn't help to fix this and there is no night mode in this camera a53 shoots video in 1080 resolution with up to 30 frames per second and overall quality is average it's not bad and you can shoot videos on youtube with it but don't expect much from this camera low bitrate no optical stabilizer which may be why some of you will decide not to buy the smartphone front-facing camera give you some nice photos ai beautification kinda works only for some quick selfies but really not more than that i would not shoot a video on this camera just something really quick for instagram stories so all that makes oppo a53 a good beginner camera phone for those of you with a minimal budget but if you have a bit more than that take a look at this option if a good smartphone for filming isn't the only thing you're looking for as a beginner on youtube i guess you might like the news i want to share with you right now a big sale is underway on the official movavi website and the cool thing about this sale is that you can find there not just some standalone apps by movavi but also many awesome software bundles at great discounts for example i recommend you check out movavi unlimited this annual personal plan includes 11 movavi programs for your creative work and one year unlimited access to the movavi effects store i'll leave the links you might need in the description so you can go check it out yourself the samsung galaxy a50 which costs around 200 us dollars the main 25 megapixel camera the ultra wide 8 megapixel camera the 5 megapixel depth camera and the 25 megapixel front facing camera if you want to make some sexy slo-mo videos you can do it but there are some limitations 240 fps available only in 720 and normal speed shooting up to 30 fps in 1080 yes no 4k just full hd there are seven shooting modes panorama pro which is not so exciting to be honest you can control iso white balance and exposure not too much for the pro mode i would suggest downloading some third-party apps for this live focus or in other words portrait mode where you can change the amount of blur in
