The personal computer with its pleasant and inviting user interface coupled with a palette of everyday applica-tions was a big step in the rapprochement between people
Graphical OSs (Operating Systems) like Windows made getting into computing applications much more available to people.
The personal computer has made com-puting accessible to small businesses, but most important the personal computer was small and cheap enough to be a household appliance. You did not need to be a large company; the computer could help with your life too. The personal computer confirmed that everyone had tasks that are computer-worthy, and the growth of applications followed this era of democratization of digital technology.
The availability of the PC to individuals allowed the following information tech explosion of the past 30 years. Pretty much every software tech company grew from the efforts of individuals with access to computers.
Since the invention of the microprocessor and parallel advances in miniaturization and decreasing costs,
Microprocessors have broken down data manipulation to the most basic forms. Those forms can be mixed and matched to allow any form of processing of data whether it be 1+1 or is this face equal to this face?
One consequence of this emerged in the 1960s with databases, which are specialized computer programs that store and manipulate data, or digitally represented infor-mation
Storing data allows there to be "memory" like ours.
To be more precise, a computer represents every num-ber as a particular sequence of binary digits (bits) of 0 or 1, and such bit sequences can also represent other types of information. For example, “101100” can be used to rep-resent the decimal 44 and is also the code for the comma; likewise, “1000001” is both 65 and the uppercase letter ‘A’.1Depending on the context, the computer program manipu-lates the sequence according to one of the interpretations.
Sidenote: Binary represents the alphabet and the alphabet can be used to express the entirety of human desires and understanding. Language Processing is an ML application.
Probably the major driving force of the computing technol-ogy is the realization that every piece of information can be represented as numbers
This is the core of MACHINE LEARNING. Everything is a number
computers were expensive and only very large organizations, such as governments, big companies, universities, research cen-ters, and so on, could afford them
Computers, and their power, are much more available now!
