So in this Artical, we will learn about the Two Port Network . So as its name suggests that two port network is the electrical circuit or the network, which contains the two ports. But to understand it in detail, first of all, we need to understand  What is Port What is port ? So the port is the pair of terminals, which connects the electrical circuit or the network to the external circuit. So through this port, any actual network or any independent source can be connected to the existing network, but any two terminals cannot be called as a port. And for that, they need to satisfy port condition if the current I, and to the one terminal of the port and the same current should lead to the second terminal. So if the pair of terminals satisfy this condition, then they can be called as a port. so if the electrical circuit or the network contains one such port, then it is called the one port network and all the basic circuit elements like the aesistor capacitor and the data out of the e...

What is Li Fi So in this Artical, we will learn about the Lifi technology, which is the abbreviation of a term light fidelity. So in simple terms, we can say that this lifi technology is nothing but light based lifi technology. And as we know, this wifi is fully network bi-directional wireless communication technology. But data is being transmitted using the radio waves while in case of a lifi technology , that data is transmitted in the form of visible light using the LED light source. So these household LED bulb and LED lamps, which are used as a light source can also be used to transmit the data. 1. How this lifi technology work So, first of all, let us understand how this lifi technology works. So if you see any LED light source. If you provide a constant current to this LED, it provides you the constant illumination or a constant brightness.  So as it is the current that is flowing through this LED bulb, the elimination or uprightness of this bulb will change. So this princip...

What is Power Over Ethernet(POE) In this Artical, we will learn what is power over Ethernet technology, which is also commonly known as a PoE. And we will also see some standards which are used for this power over Ethernet technology. Now, as we know, ethernet is the networking protocol, which is used to establish the local area network or a Len. And data is carried using the network cables or other cables. Now in Poe or power or ethernet technology , along with the data power can also be carried on this ethernet cables and using this different network devices can be powered up. So now generally the network device, which require less power are powered up using this power over Ethernet technology . So the IP phone wireless router and the IP cameras are the example of the network devices, which can be powered up using this powerover ethernet technology.  And today, if you see this power over ethernet technology , so established that millions of devices in the world are powered up usi...

What is Pic18-Q40 Microcontrollers  The pic18-Q40 family of microcontrollers combined powerful, versatile, and highly configurable core independent peripherals with advanced interconnection capabilities. These device family offers high level of sophistication into a small 14 or 20 pin space saving packages as a small as three by three millimeter. This product timely offers opposites 64 kilobyte up onto flash memory up to four kilobytes SRAM and 512 bytes up E prom system clock is speed up, up to 64 megahertz across there. 1.8 to 5.5 bolt operating voltage rains in temperatures from negative 40 to 125 degrees Celsius. What is Cache Memory Concept os Loop mesh node branch What is System in Chip What is Multiviblator Also, when you need a par savings, these devices can operate in idle, standby and power down sleep modes to balance performance with power consumption. The pic18-Q40 device family is smallest Pic. Pic18 microcontrollers ever built is suitable for a variety of applicati...

What is Multivibrator let us quickly understand about the multivibrator circuits. So this multivibrator is the electronic circuit , which is used in gleaming, the two-state devices like fifth flop. Now here, the who States refers to the two voltage of the multivibrator like plus 15 or 10 zero voltage. If you talk in terms of their digital electronics, then it can be either high or low state that here, the high state represent the logic one and the low state Ernst the logic zero. And depending the number of stable States, the multivibrator can we divide it in three types is stable, mono stable, and bi-stable melody vibrators. So in instable, multivibrator , the awkward will not remain stable in any of the two States.  And if you see the output of the multivibrator will conduce the changes between the who States. Now here, the time for which the output remains in the particular state can be decided by the passive components like resistor capacitor, and this type of stable, multivi...

1.What is system in chip Today We will see what the system on chip . So today we are living in the area of a smartphone and a tablet. And in the past decade, the technology has been evolved so much that using this smartphone and tablet, we can do almost all the stuff that we were used to do with her desktop and a laptop. So using this smartphone and tablet, we can do a stuff like gaming, web browsing for two editing, creating documents, media streaming, and many more things. And yet these devices are quite compact compared to the desktop and a laptop. And yet they contains almost all the parts which you see inside the desktop and a laptop. So almost all the components that you see inside the motherboard of any laptop or a desktop are integrated inside a single chip in the smartphone.  What is RAM What is DRAM What is Cache Memory Concept os Loop mesh node branch So the entire system, which is required to run a smartphone is in data inside a single chip. And that is known as a SOC ...
