LAN messenger LAN messenger A LAN Messenger is a instant messaging program for computers designed for use within a single local area network (LAN). Many LAN Messengers offer basics functionality for sending private messages, file transfer, chatrooms and graphical smileys. The advantage of using a simple LAN messenger over a normal instant messenger is that no active Internet connection or central server is required, and only people inside the firewall will have access to the system. A precursor of LAN Messengers is the Unix talk command, and similar facilities on earlier systems, which enabled multiple users on one host system to directly
Task computing Task computing Task computing is a computation meant to fill the gap between tasks (what the user wants to be done) and services (functionalities that are available to the user). Task computing seeks to redefine how users interact with and use computing environments. It is built on pervasive computing. A Task Computing Framework (TCF) is a framework that supports task computing, by providing support for: This definition of a task computing framework does not make reference to computational components. This is referred to as a Task Computing Environment (TCE). A TCE is a computational system that includes, at a minimum,
