What is Network Sharing and Security?

Network Sharing and Security Network Sharing: Network sharing is a feature that allows sharing of resources over a network, such as files, documents, folders, media, etc. It is made accessible to other user computers on networks. Network sharing enables data to be accessed across multiple devices or at the same time. By connecting a device to a network, other user devices on the network can share and exchange information through the network. File Sharing: File sharing is the practice of distributing or providing access to digital media, such as computer programs, multimedia (audio, images, and video), documents, or e-books. File sharing can be saved in different ways. Common methods of storage, transmission, and dissemination are manual sharing uses such as removable media, centralized computer servers, web-based hyperlinked documents, and distributed peer-to-peer networking. Network Sharing in Windows Operating System: Windows 7 and Windows 8x have the same network sharing settings...

What is computer networking? How do computer network protocols work?

Computer Networking  Computer networks are an important system of communication in today's world. A computer network refers to the connection between two or more computers. The special system in which data transfer, electronic mail transmission, teleconference etc. is done quickly through cable, modem or satellite is called a computer network. Concept of Network: A network can be created by connecting small, low-power microcomputers to a powerful or high-powered server-rich computer. Computers can be side by side, in the same nearby location, or from one city to another, or even from one country to another. The networking process started through the computer network Mini and Mainframe Computer but nowadays personal computer is widely used for networking. The interconnection and ability of multiple computers and other devices to work together in offices, courts, educational institutions or other workplaces under computer networks has brought revolutionary mobility to information exc...

What is the communication model? What is the means OSI model? Describe different types of layers?

Communication model : In the early days of computer networking, various manufacturers made communication software in their own way. Due to the different protocols of these hardware-based software, the software made by one company could not exchange data with the software made by another company. This would be a big problem. Later, a committee was formed from ISO (International Standard Organization) to eliminate this problem. This committee created a protocol model called OSI (Open System Interconnection) to create standard standards for harmonizing all communication software. This model is known as communication model. OSI (Open System Interconnection) Model: The OSI model describes how communication between computers and other networking devices will be developed. The International Organization for Standards (ISO) started working on this model in 1974. The need for the OSI model is felt so that different networking device manufacturers can produce their devices following the same sta...
