A proxy server is a computer that offers a service to allow clients to make indirect network connections to the other network services. A client connects to the proxy server, and then requests a connection, file, or other resource available on a different server.Then the proxy provides the required resource either by connecting to the specified server or by obtaining through its cache.AdvantagesThe advantages of a proxy server are as follows −It helps the clients to protect their important information from getting hacked by hackers.The proxy server is also used to enhance the security and privacy level of the client's ...

DCOM is an extension of the Component Object Model (COM). Component Object Model explains how components and their clients interact. This interaction is the way the client and the component can connect without the need of any intermediary system component.Suppose when client and component are present on different machines, DCOM replaces the local Inter-process communication with a network protocol.Neither the client nor the components are aware that the wire that connects them has just become a little longer.The COM run-time provides object-oriented services to clients and components and uses RPC and the security provider to generate standard network packets that ...

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.

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 learn the concepts of Routing Information Protocol (RIP) and Border Gateway Protocol (BGP).Routing information protocol (RIP)This protocol employs the port 520 and the routers utilize it for sharing the information over a network and avert the routing loops.It sustains the routing table for elucidating the ultimate effective manner in order to route the data.Often permits the data to result over an immersive speed in lesser duration.It determines the best route by employing the hop count.It permits the hop count around 15.If it exceeds more than 15 then the network elucidates a network is taken as unreachable.A path containing ...

Ant and maven both are build tools.They both can be used for compile, pulling dependence from repository and for creating war or ear files. Both are provided by the Apache.Ant is a tool and it doesn't have formal conventions. If you are using Ant then you have to tell what to do in XML files therefore it can't be used in different types of project setup.Maven is framework and it can also  act as a dependency management tool. It is declarative build tool so everything we can define in the pom.xml. Sr. No.KeyMavenAnt1BasicMaven is a build automation framework based on the ... Read More

SMTP and POP3 are message protocols which are required for sending and receiving the messages between the mail servers.
