Hi and welcome to Cyber Eri. My name's Anthony and I'm your local subject matter expert for Network Plus and today we're gonna be comparing and contrasting different land technologies.
So when we're talking about are different land technologies. We're talking about our local area network connections, what types of networks and what type of infrastructure can support and carry our data. Now, our most common type of network infrastructure are most common. Land technology has referred to his Ethernet.
Now, the IEEE standard that dictates
what are Ethernet specifications are is IEEE the 2.3. Now, again, IEEE is just a It's a body that writes regulations and specifications for particular technologies and the technology that we call Ethernet eyes specified by IEEE 802.3.
Now, Ethernet is our common type of network connectivity mode that we're gonna use inside our local area network. On. We talked about a lot of other types of types of technologies that we use with our wide area network. But Ethernet is gonna be our most common within our local area network.
Now, Ethernet is going to be very common commonly used with our youth are standard unshielded twisted pair and R. R J 45. Remember our eight wired, wired twisted payer inside of our one cable that connects to our eight pan r J 45 connector,
and it has different technical specifications for our different networks.
Now, when we're talking about our Ethernet, you may commonly hear our Ethernet referred to as standard Ethernet, fast, Ethernet, gigabit Ethernet, 10 gigabit Ethernet and 100 gigabit Ethernet. Now, especially when we're looking at making purchasing decisions for our different
devices on our network, we may see a switch that is referred to as a gigabit switch.
Well, what that means is that it riff it. Its support speeds up to gigabit speeds on our Ethernet. So make sure that if you are trying to upgrade your infrastructure and you're trying to make sure that your devices can communicate it a certain speed, that all of your devices, from the cables to the network interface cards to your switches and routers,
can support that particular speed.
So what's the difference between our standard Ethernet, fast Ethernet, gigabit, 10 gigabit and 100 gigabit Ethernet?
Well, the big difference between the are different are different types. Here is going to be the speed at which which it transfers. So we've talked about speed when we're talking about our networks a couple times, but let's take a little bit of a closer look at that. Now, when we're talking about our network speeds, we're talking about them in terms of bits per second. So what is a bit
well at our base layer of our computing?
Our processors and our computers can only transmit information and electrical impulses, and those electrical impulses are red as either on or off, which is represented by binary ones or zeroes.
Each of those binary digits is called a bit each of those ones, or zeros that indicate an electrical on or off, is called a called a bit.
with our standard Ethernet, we're transmitting at 10 megabits per second. So what is that? What does that look like?
Well, much like our metric system, we're gonna we're just gonna reiterate in tens and hundreds.
So we start with one bit. So if we had a
for example, we talk about 64 bit processors. We're talking about 64 individual bits. Then we have our killer bits, which is going to be 1000 bits represented by Big K little B.
Next, we have our megabits, which is what we're going to be looking at starting with our Ethernet and our megabits are going to be one million big M little B. That's gonna be our megabits.
Next, we have our gigabits, which is going to be one billion bits per second. So bits kill obits, megabits and gigabits.
Our standard Ethernet is going to run at 10 megabits per second, so it's going to run at 10 million bits per second. It's gonna transfer 10 million bits of data per second.
Fast Ethernet is going to be transferring at 100 million bits per second transfer rate.
Gigabits will be 1 1000 megabits or one gigabit one million bits of data per second.
10 gigabit will be transferring at 10 million bits of data per second,
and then 100 gigabit will be transferring at 100 million bits of data per second. You may have heard of something called a bite. Some people, you may hear people referring to file sizes or referring thio different values as a bite rather than a bit.
We're gonna will cover this just a little bit
just so that you understand what the difference is between a bit and a byte. But know that when we're talking about are different Ethernet speeds. When we're talking about our network connection, speeds were talking in terms of bits and usually one referring were referring toe files or referring thio certain referring to certain
network addresses. Then we may well be referring to bites,
so a bite is actually
eight bits. So when we're talking about in terms of our bite,
you may have heard of kilobytes
or megabytes, and so on. Ah, single bite is going to be one are a single a bit is going to be the same. A single one or zero a bite is going to be a set of eight ones or zeroes, and then a kilobyte is going to be
So you see how we're are slightly different when we're talking about our difference between our bits, kilobytes, megabytes, gigabytes, because we have that little bit of difference that we're building on.
So if you hear someone referring to transferring, if you hear a
if you hear file size someone, someone say a one gigabyte file
If you're transferring at gigabit speeds, you won't transfer that file in one second because you're gigabyte file is going to be bigger than 1000 are 1,000,001 billion. It's gonna be bigger than one billion bits because it's based off of this bite standard rather than necessarily Arbit standard. But for now,
don't worry about that much. Don't let it confuse you. Just know that when you see little B, we're talking about bits. If you see Big B or you here with the word bite, that's a that's a different story Entirely are, but our bits are going to be based off of this 1 1,001,001 billion standard.
