Bioinformatics — What? Why? How?

Bioinformatics has become a buzzword in today’s world of Science. About one or two decades ago, people saw biology and computer science as two entirely different fields. One would learn about living beings and their functions whereas the other would learn about computers and underlying theories. However, at present, there seems to be a mere separation between the two fields and this new field, bioinformatics, has emerged as a combination of both Computer Science and Biology.
