Software engineering occurs as a consequence of a process called system engineering.Instead of concentrating solely on software, system engineering focus on a variety of elements, analyzing,designing and organizing those elements into a system that can be a product,a service or a technology for the transformation of information and control. The system engineering process is called …

About software port and related to service type micromuse-lm
ABOUT SOFTWARE PORT A Software Port (usually just called a ‘port’) is a virtual data connection that can be used by programs to exchange data directly, instead of going through a file or other temporary storage location. The most common of these are TCP and UDP ports which are used to exchange data between computers …
