A hub is a networking device that is used to connect multiple devices in a network. Its main function is to receive data from one device and then broadcasted it to all its ports. It works at the physical layer of the ISO/OSI model. This is also called a multiport repeater because it does broadcast to every port in which some devices are connected. and to do this it uses fiber optics cable or twisted pair cable. It works in half duplex mode. It has many advantages and disadvantages; in this article, we will be exploring some of those which ... Read More

Computer Security means protecting your data and information from harm, theft, attackers, and unauthorized access. Let’s consider one simple example of why security is necessary. Today, children play online games by downloading them from Play Store and Chrome or using other sites. They don’t have proper knowledge about the third-party sites or malware functions attached to them. They download those games and applications on their computer, play games, and do other stuff. After some time they came to find out that some files on their computer were missing and the system was not working. Or Considering examples when some unprotected ... Read More

Mobile devices are something we keep so much private information in. It keeps our data such as personal pictures of family, and friends, special events, important documents, audio and videos, and certain other confidential files which are necessary for our life. Keeping all this information secure and private is very important and it is a challenging task to secure it. But as we know security always starts with us, we people have to be careful while sharing our data outside the world, even on social media. It can affect mental and physical health. So to keep it secure and safe, ... Read More

Telecommunication has ended up being a fundamental portion of present-day society, empowering individuals to communicate and share data over long separations with ease. It has revolutionized the way we communicate, making it quicker, more open, and more effective. In any case, like every innovation, telecommunication has its advantages and disadvantages. In this article, we are going examine the benefits and disadvantages of telecommunication, permitting readers to way better get it the impacts it has on our lives and how best to utilize it. What is Telecommunication? Telecommunication describes the long-distance transmission of information through electronic devices like phones, computers, and ... Read More

Both cloud storage options provide business solutions and cloud storage functionalities. While Amazon S3 opens the door to the various AWS cloud computing facilities, Box provides unlimited storage. As there appears no file preview while downloading, there may be some confusion while downloading them. Again, Box may crash randomly and cause some problems for first-time users. The data stored are protected against multiple failures, errors, or threats in the case of Amazon S3, while Box provides security while sharing files and also in collaboration. Amazon S3 Amazon S3 was created by Amazon Web Services in 2006 for giving a one-stop ... Read More

The Cisco Discovery Protocol is a proprietary protocol of the Cisco System. Cisco discovery protocol is a datalink layer of layer 2 discovery protocol. It provides access to media and physical addressing The main focus is to share directly connected equipment information such as IP address and operating system version to neighbors. The On-demand Routing propagates the IP prefix through the CDP protocol. It determines the data transmission format and control of network access. Link Layer Discovery Protocol is a standard protocol whereas Cisco Discovery Protocol is owned by Cisco System. The CDP supports the IEEE 8021ab version of LLDP. ... Read More

In a computer network, physical devices are used to communicate from one to another. These devices are also called Network Hardware. The primary functions in computer networks are Connectivity and controlling of the network traffic. The network can be expanded or separated using network devices. A network device to regenerate incoming signal before retransmission to the receiver over a distance in the OSI model is known as Bridge. Gateway is a node to connect two disparate networks using two different protocols. What is Bridge? A network unit in which the connection of two different LANs in the same protocol is ... Read More

The Border Gateway Protocol (BGP) features AS Override and Allowas In is used to control how BGP routing information is communicated between Autonomous Systems (AS). A routing protocol called Border Gateway Protocol (BGP) is used to communicate routing data between different autonomous systems (AS) over the Internet. Network administrators can use many BGP features to regulate the exchange and advertisement of routing information between ASes. AS Override and Allowas In are two such operations. This article explains both and their differences. AS Override AS Override could be a BGP setup alternative that permits a border switch in one AS to ... Read More

The Word Aloha generally means Hello in the Japanese Language. It works under the MAC layer of the OSI model. Multiple access protocol is a set of protocols that are used for avoiding cross-talks and to have an efficient transmission. When the data is transmitted between hosts that do not have any particular channel, then there may be high chances of data collision and crosstalk. In that case, ALOHA which is a Random Access Protocol is used to get more efficiency. ALOHA in Computer System ALOHA is a multiple-access protocol. Using this protocol, any number of data streams from different ... Read More

Satellite communication is a sort of remote communication. Satellite communication is the method of sending and accepting information or data from one point on earth to another point through a satellite. This innovation has been broadly utilized for an assortment of applications such as television broadcasting, climate forecasting, navigation, military communication, and many others. It has gotten to be a necessary portion of present-day communication systems, empowering moment worldwide communication. In this article, we'll talk about the focal points and drawbacks of satellite communication. What is Satellite Communication ? Satellite communication refers to the utilize of manufactured satellites in orbit ... Read More
