What is a Solution Package?

A solution is a deployable, reusable package that can contain a set of Features, site definitions, and assemblies that apply to sites, and that you can enable or disable individually. You can use the solution file to deploy the contents of a Web Part package, including assemblies, class resources, .dwp files, and other package components. A solution file has a .wsp file extension.
How to add the solution to the sharepoint farm and then deploy it to a particular web application is discussed below.

1. Adding solution package to the server

stsadm.exe -o addsolution -filename myEventCalendarList.wsp

OR

Use the complete location of the file, for example:
stsadm.exe -o addsolution -filename “C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN\Solution\myEventCalendarList.wsp”

Deploy solution package command

2. Deploying the Solution

Deploy the solution using the following command:
stsadm -o deploysolution -name myEventCalendarList.wsp  -url http://sp-dev/ -local  -force
Here( -url) means the web application where to deploy the solution.
OR
Goto, Central Administration > System Settings >Manage farm solutions
Now click your solution from the list (for example, myEventCalendarList.wsp).
