logical addresses

its logical ip addresing classes working at layer 3

IP Address is classified into 5 classes
class A Ranges from 1 to 126
Class B Ranges from 128 to 191
class C Ranges from 192 to 223
Class D Ranges from 224 to 239
Class E Ranges from 240 to 254

Class A,B and C are all for normal users like us.
Class D is for multicasting
Class E is for military and Research.

IP Address is classified into- 
class A Ranges from 1 to 126

Software engineering (SE) is the profession that creates 
and maintains software applications by applying 
technologies and practices from computer science, project 
management, engineering, application domains and other 
fields.

Software engineering, like traditional engineering 
disciplines, deals with issues of cost and reliability. 
Some software applications contain millions of lines of 
code that are expected to perform properly in the face of 
changing conditions, making them comparable in complexity 
to the most complex modern machines.

Software Engineering is a profession which deals from 
designing , coding and testing and maintenance of the 
software.  In other words it creates and maintenance 
software applications...

Monitering and measuring the strength of the development 
process

systematic rules and procedures that we follow in 
developing the software application.
