The era of computing began in the 20th century, with an enormous investment on computational research. Software programing languages were the foundational blocks of history of computing. Progressive research then led to networking, bringing about the formation of connectivity. Along with these creations, there was an accompanying factor of compromise on data privacy and hacking of data. This factor was the introduction to cybersecurity.
