Intel C4004 Microprofessor
Intel launched their CPU processor in 1971. Intel's team (led by Federico Fagginand Masatoshi Shima) was set on building a processor that could build on RAM instead of shift resistors and ROMs. Polysilicon was used instead of metal as it allowed for the engineers to put more components closer together on the chip. This invention was used in teller machines, banking systems, and cash registers. This helped society by allowing more people to have access to banking and speed up the economy. -
Floppy Disk by IBM
In 1971, Alan Shugart and his team introduced the Floppy disk. The initial floppy disk had data written on it and allowed for computers to read from the disk and held 100 KBs of data. The technology allowed for researchers and the general public to transport data and information from computer to computer. Floppy disks were used to store data from one computer to another; therefore this has allowed society to transport and share information without having to use one computer. -
C Programming
C (a programming language) was created by Dennis Ritchie in the early 1970s. It is primarily used for computer architecture and heralded for working both with mini computers and personal coding to large scale supercomputers. It has a sister programming language known as B as well. C programming languages are used to build widely used systems (SQL, Windows, Office, MacOS). All those systems listed are used in our day to day -
UNIX Rewritten in C
Initially the Unix team was working on a large scale called Multics. As time went on and faith in the project fell, the team switched to focusing on a smaller system called Unix. In the early 70s, the Unix system was updated and added text processing capabilities and rewritten in C. Rewriting it in C made the code more compact and easier to use on other processors. Unix is free and allowed people to program their own secured websites as Unix was ideal for webhosting -
SQL Creation by Raymond Boyce and Donald Chamberlin
Boyce and Chamberlin were working at IBM in the 1970s and came up with SEQUEL after reading Edgar Frank Codd's paper on Relational Models. IBM was hesitant to launch the new SQL system as they were afraid it would detract from their current database systems. Oracle launched their SQL product is 1979 and have been known as the SQL pioneer since then. SQL is used to host and extract data for most companies. for their customers or employees data and retrieve it when needed
