Token bus is a popular standard for token passing LANs. It was standardized by IEEE standard 802.4 and is mainly used for industrial applications. In a token bus LAN, stations are used to create a virtual ring, and tokens are then passed from one station to another using this virtual ring. Every station or node ...
Access control is a data security method that allows organizations to manage who has access to their resources and data. Secure access control uses policies that ensure users are who they claim they are and are provided with the appropriate levels of access control. Along with providing access control features, Network access control (NAC) also covers ...
The RIP (Routing Information Protocol) is a distance-vector routing protocol. Routers that use the distance-vector protocol send all or a portion of their routing tables to their neighbors in routing-update messages. The Routing Information Protocol employs a distance vector algorithm to determine which path a packet should take to reach its destination. Each RIP router maintains its ...
Digital signatures allow us to verify the author, date, and time of signatures and authenticate the message contents. To verify the integrity and validity of digital messages and documents, it employs a cutting-edge mathematical technique. It helps us combat the issue of impersonation and tampering in digital communications and ensures that the contents of a message are ...
TCP/IP stands for Transmission Control Protocol/Internet Protocol and is a suite of communication protocols that makes data exchange between two devices possible. TCP/IP specifies how data should be packetized, addressed, transmitted, routed, and received on a network by providing end-to-end communication. As compared to the OSI model, which is a theoretical model, TCP/IP is an application and practical ...
Overview The world’s current population is around 7.6 billion people, and the number of devices connected to the internet is estimated to be over 50 billion, implying that each person uses approximately 6 internet-connected devices. This number has been increasing since the day when the first network, ARPANET was made. In today’s world, one cannot imagine life without the internet. In this article, ...
