hey guys in this video we're going to talk about a couple of different email protocols and these are pop3 and IMAP now these protocols are used for retrieving email from an email server so for example if you're using an email client such as Microsoft Outlook you would configure outlook with either pop3 or IMAP to retrieve your email on a computer and you can also use these protocols on your tablet or smartphone to retrieve your email so you can use either one the choice is yours but the question is which protocol do you want to use is one better than the other so that's what we're going to talk about so let's talk about pop3 first now pop3 stands for post office protocol 3 now pop3 is the simplest of the two protocols because the only thing that pop3 does is download the email to your device from a mail server and it only downloads what's in your inbox folder which is where your email is and that's pretty much it it doesn't download any other folders or ...

hello everyone in this article we're going to talk about the difference between a hub a switch and a router now all three of these devices are similar but there is a difference in the way they handle data so we'll first talk about a hub now the purpose of a hub is to connect all of your network devices together on an internal network it's a device that has multiple ports that accepts Ethernet connections from network devices now a hub is considered not to be intelligent because it does not filter any data or has any intelligence as to where the data is supposed to be sent and that's because the only thing a hub knows is when a device is connected to one of its ports so when a data packet arrives at one of the ports it is copied to all of the other ports so all the devices on that hub sees that data packets so again a data packet comes into one port then the hub will just rebroadcast that data to every port that has a device connected to it so even if this computer here ...

to show you how to set up an FTP server in Windows 7 create a user account and access your FTP from inside of your network and outside of your network so let's begin click on start and then type run and click on the run program here type CMD and click OK it's going to open the command prompt here type IP config and press Enter and this here is your IP address keep it in mind or write it down now I'm going to close here and I'm going to create in my desktop a folder that my FTP users are going to be accessing via the FTP site I'm going to name this avoid errors and now we are ready to install a is so click on start then click on control panel then click on programs and features and click on turn Windows Features on or off and then look for Internet Information Services checkmark that and then expand expand FTP server and now put a check mark on FTP server FTP extensibility FTP service web management tools and world wide web services and then click OK most IISS instal...

a lesson on networking command-line tools and I will tell you that in this lesson well we're gonna do just that we are going to go through a list of command-line tools and make sure that you understand what they do and then I'll even go in and demonstrate some of them for you so the first couple of commands that I want to go over with you are very similar in nature not only are they named similarly but the functionality is pretty much the same these two commands are IP config and then I F config now both are used to view tcp/ip configuration the difference is IP config is for the Windows operating system whereas ifconfig you will find in things like Unix Linux and Macintosh we will take a look at the IP config utility in just a few minutes now this next utility I will tell you is one that is the most powerful yet most simplistic utility out there and the name of this utility is ping okay it's just simply the ping command and this is something that many people have heard o...

the invention of transistors revolutionized human civilization like no other technology at the heart of a smartphone lies a processor and this processor holds about two billion transistors what do these incredibly tiny devices do how do they work transistors can act like a switch with no moving parts they can amplify a weak signal in fact amplification is the basic function of a transistor first let's understand the basis of transistors we will come back to the application part later transistors are made of semiconductors such as silicon each silicon atom is bonded with four neighboring silicon atoms silicon has four electrons in its valence shell let's replace this silicon atom with a four-handed Smyly each hand holds one electron each one of these electrons goes for sharing with a neighboring silicon atom this is known as a covalent bond currently the electrons are in their valence band if the pure silicon has to conduct electricity the electrons have to absorb some energy an...

see how computers add numbers in one lesson inside a computer you'll find a motherboard the motherboard acts like the chassis inside a car giving all the components something to connect to on the motherboard is the microprocessor most micro processors have some jagged metal on top called a heatsink to prevent overheating if you remove the microprocessor and look underneath you'll see a lot of wires sticking out that connect from the holes on the motherboard to the main part of the microprocessor the microprocessor is made up of different areas that do different things such as adding or storing numbers these areas are mostly made up of one thing though the transistor here is a 3d view of one the transistors base is a semiconductor which sometimes conducts electricity and sometimes does not the semiconductor has positively charged areas and negatively charged areas electricity will not flow between the two yellow areas unless a conducting channel is opened up in the green area a ...

hello everyone in this Article we're going to talk about one of the most important parts of a computer and we're going to be talking about primary memory or temporary storage and this is called RAM Ram stands for random access memory RAM is stored on the motherboard in modules that are called dims dim stands for dual inline memory module a dim is a dual inline module because it has two independent rows of these pins one on each side a dim memory module has either 168 184 240 or 288 pins and then the dim is installed on the motherboard in the memory slots a motherboard can have a various number of memory slots the average motherboard will have between 2 and 4 of them in order for data or program to run on a computer it needs to be loaded into Ram first so the data or program is first stored on the hard drive then from the hard drive it's loaded into Ram and once it's loaded into Ram the CPU can now access the data or run the program now a lot of times if the memory is to...
