Let There Be Light: Exploring the World of LiFi Communication In today's fast-paced digital era, there has been a constant search for more efficient and secure ways to transmit information. Enter LiFi, or Light Fidelity - an emerging communication technology that uses LED lights as a gateway for data transfer. Unlike its radio-wave-based counterpart, WiFi, LiFi harnesses visible light communication (VLC) in the electromagnetic spectrum for high-speed and secure bidirectional data transmission. This breakthrough holds immense potential in revolutionizing wireless systems while significantly reducing electromagnetic interference. Key Takeaways LiFi, or Light Fidelity, is an emerging communication technology that uses ... Read More

Subnetting Subnetting is the technique of dividing a huge network into many smaller parts, these logical divisions in an IP network reduce the network traffic and also achieve better performance of the network path. This is used in large organizations when many host devices are connected to a single network where the routing process is carried out during traffic and also increases security. Each device connected to the subnet communicates with one another by using routers. An IP address is used to classify devices on the network which has two parts, the first part represents a network of the address ... Read More

Multicast and broadcast are two often used terms in computer networks and refer to two different methods of transferring data from one source host to multiple destination hosts. Multicast means sending data from one source host to a particular group of hosts, while the broadcast is sending a data packet to all the hosts which are present in the same network. The same network means the network of the source host. In this article, we will be exploring the differences between the broadcast and Multicast in detail, as their benefits, drawbacks, and the situation in which one method is preferred ... Read More

Rake generally means the tool used in the garden to get all the fallen leaves. In wireless communication, a rake receiver is used in CDMA systems and the radio signal when reflected from any type of obstacle will travel with a different type of amplitude, phase, and delay. The people behind the rake receiver are Price and Green. This is a type of receiver that uses radio signals and is divided into different signals then it uses the correlates to compare the received signal with the original signal. Rake Receiver Definition Rake Receiver is used to oppose the characteristics of ... Read More

The term “Cloud Computing” was proposed in the year 1950s that gives internet-related services and it emerged from distributed computing to the current technology called cloud computing. Then Grid computing was proposed in the year the 1990s and it came into existence after the invention of cluster computing. As the computing structure includes different computers or nodes, in this case, the different nodes are placed in different geographical places but are connected to the same network using the internet. Grid Computing Grid Computing comes under the evolution of cloud computing which includes all the nodes that are located in different ... Read More

GPS stands for Global Positioning System which was initially created for military usage. The first fully functional GPS was in 1995 in the US and was then included in vehicles in 1996. It is nothing but a group of satellites that revolves around the earth and recursively send messages to the earth's surface which are received by various devices to calculate the optimized location of the receiving device, this calculation requires information from at least 4 satellites which includes the coordinate positions and clock deviations. This is known as space technology. It is implemented everywhere on the earth without 100% ... Read More
