How A CPU (Central Processing Unit) Works !

Hi, we'll be discussing classical computing, more specifically - how the CPU operates and CPU parallelism. [Music] In the previous video in this series we discussed the shrinking of the transistor, allowing for more powerful and efficient computers, as well as the end of Moore's Law based on the miniaturization of the transistor within the next seven to ten years. Be sure to check it out for some background context for this video. Now in that video when referring to computing performance, we were focused on classical computing based on the CPU.

Classical computing, is essentially the digital computer, almost every computing device on the market today is a classical computer. Classical computers operate in serial, in other words, as mentioned in the first video in the series, Computing Origins, executing various instructions extremely fast in 'order', but to the average user it appears to be running them in parallel, meaning multiple instructions at a time.

The Best One New Feature You Must Enable In Android

What’s up guys, I’m ThioJoe. And forgive the sarcastic title, but seriously if you didn’t know, there has been a MAJOR new feature rolling out across all Android phones having to do with a new generation of text messaging on Android. And based on the research I’ve done, it doesn't require any specific version of Android, so it’s not like you need to update android to get it. And it should work on all US carriers too, with international support coming.

The feature I'm talking about is essentially a new texting platform called RCS which stands for “Rich Communication Services”. I’ve talked about this in the past,it’s been something Google has been working on for years, and it’s finally being rolledout. And like I said, you can think of it like“next gen” texting that replaces the ancient SMS text message platform, and adds lots ofnew functionality very similar to how iMessage works on iPhone, if you’re familiar withthat at all. So let’s go over how to enable the feature,and then we can go over the benefits.

The first thing to understand is lots of phonemanufacturers have their own default text message app, and it must support RCS if you’reusing theirs, which most don’t yet. So you’ll probably need to download Google’s“Android Messages” app which comes with stock android phones and use that. I believe Samsung has also support for RCStoo though. Anyway, to enable RCS in Android Messages,first make sure the app is up to date through the play store, then you just need to go intothe options and look for “chat features”. It will probably have you type in and confirmyour phone number, and then you’ll see more options for stuff like typing indicators,read receipts, and “chat messages”, which with that one you can see can use wifi fortexting.

So this is basically the Google equivalentof iMessage. With Samsung, assuming your app is up to date,you’ll apparently also have an option in there for “advanced messaging”, at leastaccording to Verizon’s website. Unfortunately I don’t have a Samsung phoneto verify this with, so your mileage may vary. But worst case scenario, you should be ableto just download the Android Message app no matter what phone manufacturer you have. Another thing I’ve read, but might not bethe case anymore, is that if you are trying to enable RCS on a non-pixel phone, you mighthave to download the “Carrier Services” app from the Google Play store.

It is an official Google app so it’s notsketchy or anything, but it may be necessary if it’s not pre-installed on your phonealready. And you can see on the app store page it doesmention it allows support for ‘enhanced messaging features’ which is another termbeing used for RCS. So you may also see it marketed by other companiesunder names like “SMS+”, “Message+”, “Advanced Messaging”, “Enhanced Messaging”,or even just “Chat”, or something similar. From my understanding, phone carriers themselveshave not really been offering RCS support even though they all promised they would. So for now, it seems Google is taking on theload for the platform, kind of like how Apple does with iMessage.

Then apparently when carriers actually startrolling out RCS on their own networks in 2020, the switch should hopefully happen seamlesslyin the background. Now as for what features you get with RCS, there are several. As I mentioned, there is support for advanced functionality like reading receipts, typing indicators, also higher quality images and videos so they won't be shrunk down to a postage stamp when you send them. It also supports messaging over WiFi and data which is great in situations where you don’t have a cell signal, but do have access to wifi.

There’s also improved functionality for group text messages, like being able to name group chats, and the ability to add or remove people from groups. Though I should point out RCS does not offer to end encryption like iMessage, and also RCS is not compatible with iMessage either. So if someone on an iPhone texts someone onAndroid, they’ll still show up with a green bubble, even if they use RCS. The final important note is that these RCS features will only work if the other person you are texting has also enabled this feature in the messaging app, assuming they’re using one that supports it. You’ll be able to tell if someone has done this because their text message bubbles will show up as blue. Also at least for now, when you go to send a message, it will say “Chat Message” instead of “Text Message”. Because this is such a new feature, and an optional one at that, don’t be surprised if you don’t see many people with blue bubbles using this.

But the good news is if you know they use android, you can tell them about this feature, and if they use either Android Messages or Samsung, it’s trivial to enable. I also believe Google will be making this new feature more prominent over the next few weeks and months, so people will find out about it. And I’m sure lots of phone manufacturers will start enabling this feature on their own proprietary apps, so they can promote it as a feature to customers. Another cool related feature having to do with Android Messages is, if you didn't know, you can actually send text messages from the web,  if you go to “messages.google.com/web”.

Then you can use a QR code to link your phone to the web app. This should allow you to not only send RCS messages but also text messages from your computer. So if you do have access to this new feature, there’s really no reason NOT to enable it if you use an app that supports it. And even if you use a third-party app like extra which is really popular, you can still be aware of it, because I’m sure those apps will start adding the feature soon enough. You even also be the cool friend who introduces friends to this awesome new feature and impress people if they don’t know about RCS yet. Because realistically most people probably haven't even heard of it yet. But anyway this was more of a short video, but if you guys want to keep watching, I highly recommend a video I made recently talking about 10 ways to make your Android phone faster, which I think you’ll really like. So I’ll have that pop up right here, you can just click on that.

7 Best Free Windows Program (You Should Have!)

If you're like me, you're always on the lookout for cool new software that might be useful to you. So as usual, I've got a new list of awesome programs that you should REALLY know about if you don't already. And of course, these are all free, and will all work on windows. Though many will also be compatible with mac as well. And at the end of the video, if you're interested, I'll have links to other lists I've made of free programs, chrome extensions, that kinda stuff. But enough rambling, let's go.Program No.  1Starting off, a very useful program that I hope most of you have already, called 7-zip. It's an extremely popular program for compressing files and extracting them from all sorts of file containers. It's very similar to the infamous WinRar, except free, and supports more file types. So if you've ever come across a weird file container you've never seen before, this will handle whatever you throw at it. Anything from zip files, to…
