In Data Communication, the data are transferred from the client to the receiver. During this transmission, there may be a chance of an error occurring due to network problems, interference and using any other ways. So, the error needs to be detected and corrected. For both error detection and correction, we can use various methods like linear code and Convolution code. Linear codes are efficient one for error correction of the transmission bits between the hosts, while convolution code encodes in a timely fashion. What is Linear Code? Block code is the one that encodes data within the block and ... Read More

Voice data can be sent from one device to another using telephone devices or wireless mode. Voice communication works for all factors including long−distance, local areas, mobile devices, and international numbers. This technology is useful for normal customers and businesses as it provides other features like caller ID, voicemail, text messaging, team chats, and call recording that may not be available in all phone services. These voice and multimedia sessions can be communicated over an Internet connection using fixed or non−fixed methods. Fixed VoIP Fixed Voice over IP has a physical address and the number is assigned to the owner ... Read More

A network contains several groups of devices that communicate with one another through links. Devices are represented as hosts that are connected through switches, routers, hubs, modems, and access points with transmission mediums for communication purposes. Communication protocol specifies set of rules for exchanging data over a suitable network. Each protocol differs in its communication properties and can be connection−oriented or connection−less with a circuit or packet−switching techniques. Most of the common protocols used in networking are IEEE 802, Ethernet, Wireless LAN, SDH, ATM, Routing, etc. Here Ethernet and Synchronous Digital Hierarchy (SDH) are types of communication protocols used in ...

Data transfer can be initiated from the user or client machine by sending a request and at the other end, the server or destination device receives the request, verifies and validates it before sending a response message. Data transmitted are converted into packets or bits as per each layer’s functionalities. The application layer of the OSI model is the top layer near the end user, and communication happens between the application layer protocols and the user. This layer provides options for file sharing, data transfer, and database access. FTP File Transfer Protocol is used for sharing files from sender to ... Read More

IoT requires a network that can transmit data over a long range with low power and at a low bit rate but cellular networks like 3G, 4G, and 5G were not optimized for this. So the cellular body 3gpp which is third generation partnership project came up with the NB standard in release 13 in 2006 with releases 14 and 15 they upgraded the standard NB−Iot and with release 16 in 2020. LoRaWAN technologies are the ones that give voice to non−living things. What is LoRaWAN? LoRaWAN stands for Low Range Wide Area Network. It is a communication protocol ... Read More

What is Telegram? Telegram is a messaging service that can be used on any platform. The messenger could be used in 2013 on iOS and Android devices. And it is now being used by 550 million users per month. Telegram is popular because it gives priority to security, encryption, and privacy. A single account can be used on multiple devices while multiple accounts can be used on a single device. Messages can be issued and received without sharing a phone number. Why Telegram Alternatives? Security is not available in the group chat No backup available for secret chats Telegram ... Read More

Optical multiplexing developments like Coarse Wavelength Division Multiplexing (CWDM) and Thick Wavelength Division Multiplexing (DWDM) are utilized to extend the capacity of fiber-optic networks. CWDM livelihoods a little number of wavelengths scattered 20nm separated to transmit signals over a single fiber, whereas DWDM businesses a more noteworthy number of wavelengths scattered since it was 0.8nm confined for higher bandwidth. While both improvements combine particular signals onto a single fiber, there are one or two noteworthy contrasts between them. In this article, we'll investigate the contrasts between CWDM and DWDM. CWDM (Coarse Wavelength Division Multiplexing) CWDM technology uses a ... Read More

The LAN switches and SAN switches are two different types of switches that are used for different requirements. LAN switches are mostly used in Local Area Networks to establish connections between computers, printers, etc. in one particular single location. They establish communication and manage network traffic within a network. SAN switches are used in Storage Area Networks. They are used to establish the connection between storage devices like tape libraries and disk arrays. The function of SAN switches is to provide storage and retrieval of information efficiently and to make sure that the data is available to the servers ... Read More

The Internet of Things (IoT) is a network of connected devices that can communicate with each other, share data, and perform tasks without human intervention. The importance of communication in IoT cannot be overstated, as it is the foundation on which the entire system is built. The devices that make up the IoT ecosystem need to be able to communicate with each other in order to function properly and achieve their intended purpose. Effective communication in IoT enables devices to share data, receive instructions, and respond to requests in a timely and accurate manner. This is critical for the successful ... 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
