  • FORTRAN or Formula Translation: This translated the binary language (0 and 1) of digital computers into everyday language that can be understood and used by all.
  • Integrated Circuits or ICs: Until they were invented, signals were amplified using vacuum tubes. Invention of transistors reduced the size, and power consumption of amplifiers. This caused a revolution in information technology, because using these could actually make a fully integrated complex electronic circuit on a single silicon chip.
  • Relational Database Management System, or RDBMS: Earlier, these files were stored in magnetic tapes, then in floppy discs and now in CDs and pen drives.
  • Local Area Networks (or LANs): A wireless broadcast system to interconnect computers.
  • Ethernet: It allows multiple computers to share and exchange messages and files through cable connections. 
  • Public Key Cryptography: To open your phone or a computer, you need a passcode, which is secure and known only to you. And when a bank or a sender sends you a ‘confidential’ message, they too send a secure passcode (e.g., OTP). This aspect is what is known as an encryption system. This public key cryptography is one of the Innovations.
  • Computer Graphics: These are built-in programs that not only allow you to take photographs, movies and send them using applications like WhatsApp, Facetime and such.
