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 ...

Mobile networks are used for internet connectivity, message services, finding locations, and other types of transmission. Networks that have evolved from 2G to 5G with advanced features in each generation to achieve better performance, reliability, bandwidth, etc. to attract customers by satisfying their requirements and beyond it. Using GPRS users can communicate with other users by text, multimedia messages, video conferences, and much more. DGPS is used for locating the reference based on the fixed points. Communication is made between the satellite and the base station tower to trace the relative locations. GPRS Global Packet Radio Service allows mobile networks ... Read More

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

OSI model consists of seven layers for data communication over the network. Each layer does its functions and interacts with the above and below layers. 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 using protocols such as HTTP, SMTP, FTP, TFTP, DNS, and TELNET. FTP File Transfer Protocol is used for transmitting files from sender to receiver. ... Read More

Baidu Cloud is a service introduced by China that is used particularly in some parts of China and not used in other countries. It provides a wide range of features that are provided. High−resolution pictures and videos are kept safe and secured in iCloud by iCloud Photos, with lightweight, space−saving copies on all of our devices. No matter what device we are using, iCloud Drive makes it simple to access and share the files and folders we save. Some of the other features included in iCloud are family sharing, photo library, and drive. What is iCloud? iCloud provides users with ... Read More

HTML and HTTP are related in the sense that HTML is used to create web pages and HTTP is used to transfer these web pages from a server to a client. The HTML programming language is used to generate Web sites, but the HTTP protocol controls how Web data is transferred across the internet. HTML essentially serves as a description language for information supplied through HTTP. In technological terms, HTML and HTTP are two different topics, but with the help of the web pages created using the HTML language it is executed. HTML and HTTP Definition The Internet has got ...

HTTP is used by the World Wide Web for sending the request to the client and respond to them accordingly. It follows the centralized method of the server−client approach. Data can only be accessed if the server is active and running and no links are broken. Data is requested using the address where it is hosted. Since many users are making simultaneous requests to one server, the bandwidth is limited. While in IPFS it follows the decentralized network, rather than requesting data from a specific location or server, we make our request using a special identification that corresponds to the ...

Both ICMP and IGMP are the network protocols of the OSI (Open System Interconnection) model. ICMP will track the messages and finds whether the data receives the destination of the network and IGMP will manage the users of the network. ICMP only diagnoses the network but does not involve in managing it. When a person working on the computer searches for some data on the Internet without an internet connection it gets an error message like the destination is unreachable and these types of error messages are sent using ICMP protocol. What is ICMP? ICMP comes under the network layer ... Read More
