Software Bugs with Fatal Consequences

In todays world, it is almost impossible to live without using some kind of software. Almost any equipment we can think of need software to work. Software makes our lives easier but Software Bugs can sometimes be deadly.

A Software Bug is an error, flaw, mistake, failure, or fault in a computer program that prevents it from behaving as intended (e.g., producing an incorrect result). Most bugs arise from mistakes and errors made by people in either a program's source code or its design, and a few are caused by compilers producing incorrect code.

We all have for sure heard about big and small bugs in common software programs like windows etc. and the consequences of them. According to a newly released study commissioned by the Department of Commerce's National Institute of Standards and Technology (NIST), Software Bugs cost US Economy an estimated $59.5 billion annually
