Ajith SIf you are going to invest your time to elevate your computer skills, I would recommend you work on Microsoft Excel (or any other similar type of calculation/database software). Let's face it: As engineers, we work with numbers and calculations everyday. Not a workday goes by where I'm not using Excel in some fashion. There are so many useful functions in Excel that go unused by most people: Learning how to develop formulas and spreadsheets, how to build & work with Pivot Tables, how to create macros to perform a series of operations, the "vlookup" function - Once you develop a level of comfort in Excel, you will be amazed at the speed at which you can build spreadsheets quickly & functionally. Cheers!!
