What is process ?

In computing, a process is an instance of acomputer program that is being executed. It containsthe program code and its current activity. A processmay be made up of multiple threads of execution thatexecute instructions concurrently.

A computer program is a passive collection ofinstructions; a process is the actual execution of thoseinstructions. Several processes may be associated withthe same program; for example, opening up severalinstances of the same program often means more thanone process is being executed.

Overview

Process Viewer provides facilities like viewrunning process with their memory consumption,process start-time, kill selected process, view thefully qualified path from where .exe file is resides andmore important it manage user wise history forfurther usage.

Process Viewer is multi threaded applicationthat provides various useful functions for processesand application running in user system.“

User Interaction

Application FunctionsView Processes

Shows list of running processes including informationlike process Id, process name and process memory usageand starting time. List will be refresh when new processarrives or terminate.

Kill ProcessUser can terminate unwanted process.

Process PathUser can view full path of executable component

though can be also useful in detection and removingspyware , virus or any unwanted process/Application. Inprocess viewer show path where component is loaded.

Application FunctionsHistory

Process viewer manage user-wise process log as ahistory. Application doesn’t require user authentication itwork on system authentication So, There is no need forremember username and password. User can view onlyhis/her history for particular time interval. It displaysprocess name, process start-End Date&Time.

So user can let know which process had start andwhen it was terminated.

Run in BackgroundThis application can also run in background. User

can also back from background mode.

Understanding Application Architecture

Technology Used

MySQL, the most popular Open source, relationaldatabase management system, is developed,distributed, and supported by Oracle Corporation.

Pthread

The POSIX thread libraries are a standards basedthread API for C/C++. It is most effective where theprocess flow can be scheduled to run on anotherprocessor thus gaining speed through parallel ordistributed processing.
