Token ring is a physical unidirectional ring, where the systems are connected to the ring through some interface.In the token ring a special frame is called a token which is always circulated on the ring. If a system has to transmit then it needs to acquire the token without a token no system can transmit. Only one system can transmit at a time. Hence it is collision free protocol.The token ring source is responsible for removing the frame from the ring. In normal token ring operation, a station sending information holds the token until the sending data circles the entire ... Read More
Network is a connection of two or more systems which are used to share resources and information.Network CommunicationFlow of information among the group of members is a communication network. Network helps managers to establish contacts in different patterns through communication flows.The network depends on the magnitude of the organisation, nature of communication channels in the organisation and the number of persons involved in the process. There can be many patterns of communication networks.Function of Communication devicesThe functions of communication networks include the following −It is the way of coordinating the activities of individuals, relationships, groups and other sub-units within the ...

Dynamic Host Configuration Protocol (DHCP) is a network management protocol which is used to automate the process of configuring devices on IP networks. Therefore it allows them to use network services like DNS, NTP or any other communication protocol based on UDP or TCP.DHCP snoopingDHCP snooping is a series of techniques in computer networking, which are applied for improving the security of a DHCP infrastructure.When DHCP servicers are allocating IP addresses to the client on the LAN, DHCP snooping can be configured on LAN switches in order to prevent malicious or malformed DHCP traffic, or rogue DHCP servers.Apart from that, ...

To begin with, let us learn the concepts of firewall and proxy server.FirewallIt is used to provide security, mostly from external networks such as the Internet. It is the combination of software and hardware to allow, deny, monitor, and block any and all data transmissions occurring from a specified internal network.Firewalls evaluate, allow, or deny network traffic based on certain predefined rules set-up based on IP addresses or its range, port numbers, protocols, and few other factors. It provides good traffic management.Firewalls defend against external threats refusing or denying unauthorized requests, transmissions, and connections to the router, network, application software, ...

Let us begin by understanding the concepts of advanced message queuing protocol (AMQP) and HyperText Transfer Protocol (HTTP)AMQPAdvanced message queuing protocol (AMQP) is a message protocol that deals with publishers and consumers. The publishers produce the message whereas the consumer picks the message and processes it.Given below is the pictorial representation of AMQP −This protocol is used in client-server messaging and in IOT device management. It allows the messages to be passed between applications.AMQP is a new standard design to meet financial institutions and it enables the interoperation, sharing which allows business to work together in a wide infrastructure.AMQP secure ...
