The computer is the most popular topic in 21st century. Spread of computing in every field caused to vast development of computer science as an unique field. When we are talking about information technology, we could not forget the duty of computer software has been done. If we talk about computer programs, they are result of one or more computer software's. Computer programmers do make programs using software. Software is also a program that made by programmers. Usually it is called computer languages. There are so many langues for different platform. 

    Beginning of this century people were discussing about globalization. I personally believe that computer software has been doing great work to make this whole world cover by information technology.In between desktop computer to smart phone people are connected by world wide web. Now it is not a difficult thing to use computer for our daily basis. 

   As a student, my interesting part was studying about artificial intelligence (AI). Artificial intelligence is a program or theory that can perform a task which normally human can do. Artificial intelligence used in many different forms. 

• Military : Missile technologies, GPS system, Navigating plans
• Educational : Online databases, Educational sites,search engines 
• Scientific : Controlling robots
• Research : Identifying DNA
• Entertaining : Audio/Video players, Music composing software.

  A nice example of artificial intelligence is self driving car. Known as Google car. First introduced by Google and it contains artificial intelligence that can identify objects and then can navigate the vehicle without any failure. So most probably this kind of vehicles will be on market form next year according to Google news.
This is a good result of development of software engineering as same as artificial intelligence.

  In software engineering field mainly programmers make software programs. But they are help to designing,maintaining,updating software according to people's needs as well. Career as an software engineer is a high paid job, as same as it has lot of responsibilities. After engineers done with software they will have to update it, looking for errors, and again make some necessary changes. So it is cyclic process that never ends. So it is called good software if it is always updating, and it will help to maintain good customer service. Finally it will be user friendly and error free.

    Thanks to development of software has changed people's life a lot. Online banking, Social networking, E-mail,Voice/Video chat, online news providers, already have made our day to day life easier. By using personal computer or smartphone people do their business at home. For a example, scheduling for a doctors appointment is very easy task. Now you can call or go to the company's web site and schedule an appointment. After that every detail will be stored in company's data base system. which is controlled by computer software. so it will be more easy and trust worthy system.

  These are the benefits that we have today because of software development. As same as computer software has properly link to the other fields.
