MCA Or MBA Which Is Best? (MBA or MCA Which Is Better)

It is good to do a master of computer applications at present time. 

The reason for this is that today's era is the computer era and all the work is being done on the computer only. 

Today there are more job opportunities in the computer field. 

For this, it is necessary to have a good understanding of technology. 

This means you should have command over programming languages like - Java, C, C++, etc. 

Then MCA can be the right option for you.

What Next After MCA?

After doing MCA you can have many job opportunities. 

You can start your own business. 

Many types of technical jobs and support systems are in demand in the market. 

Some of them are prominent - hardware engineers, cyber security analysts, web designers and developers, data scientists, software consultants, IT support, systems analysts, and app developers.

Now come to the point.
