SmartSockets: Solving the Connectivity Problems in Grid Computing Jason Maassen and Henri E. Bal Dept. of Computer Science‚ Vrije Universiteit Amsterdam‚ The Netherlands jason@cs.vu.nl‚ bal@cs.vu.nl ABSTRACT Tightly coupled parallel applications are increasingly run in Grid environments. Unfortunately‚ on many Grid sites the ability of machines to create or accept network connections is severely limited by firewalls‚ network address translation (NAT) or non-routed networks.

A Brief Introduction Network Programming and Encryption Rich Lundeen Introduction This paper is the report of an exercise in socket programming and encryption. The objectives of this project were as follows: ● ● ● ● To create two programs‚ a client and a server The server broadcasts its public key to all who connect A client attaches to the server and exchanges a session key using public key encryption A message is passed between the client and the server encrypted with a symmetric key

Workshop Safety Practices Any accident may happen in the workshop while dealing with metal‚ tools and machines mostly because of sharp metal edges and rotating parts of machines. The accident may cause a serious injury that can even be lethal. Therefore‚ to avoid the accidents‚ following are a few steps that we should follow during the work in workshop: There are rules and regulations provided to use every machine available in the workshop. We should strictly abide by them. Take help from manuals

Socket Concept www.techterms.com/definition/socket When a computer program needs to connect to a local or wide area network such as the Internet‚ it uses a software component called a socket. The socket opens the network connection for the program‚ allowing data to be read and written over the network. It is important to note that these sockets are software‚ not hardware‚ like a wall socket. So‚ yes‚ you have a much greater chance of being shocked by a wall socket than by a networking socket.
