A distributed denial-of-service (DDoS) attack is a malicious attempt to disrupt normal traffic of a targeted server, service or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic. DDoS attacks achieve effectiveness by utilizing multiple compromised computer systems as sources of attack traffic. Exploited machines can include computers and other networked resources such as IoT devices. From a high level, a DDoS attack is like a traffic jam clogging up with highway, preventing regular traffic from arriving at its desired destination.

The terms “deep web” and “dark web” are sometimes used interchangeably, but they are not the same. Deep web refers to anything on the internet that is not indexed by and, therefore, accessible via a search engine like Google. Deep web content includes anything behind a paywall or requires sign-in credentials. It also includes any content that its owners have blocked web crawlers from indexing. Medical records, fee-based content, membership websites, and confidential corporate web pages are just a few examples of what makes up the deep web. Estimates place the size of the deep web at between 96% and 99% of the internet. Only a tiny portion of the internet is accessible through a standard web browser—generally known as the “clear web”.

Originally developed by IBM in the 1950s for scientific and engineering applications, FORTRAN came to dominate this area of programming early on and has been in continuous use for over half a century in computationally intensive areas such as numerical weather prediction, finite element analysis, computational fluid dynamics, computational physics, crystallography, and computational chemistry. It is a popular language for high-performance computing and is used for programs that benchmark and rank the world's fastest supercomputers.
