Mainframe Era (1950s - 1960s)

first business computer (room-sized monsters)
functions as data processing such as scientific calculation and accounting
primary work was to organize and store large volumes of information that were tedious o manage by hand
In the late 1960s, MRP (Manufacturing Resources Planning) systems were introduced
MRP allowed companies to manage the manufacturing process; making it more efficient
From tracking inventory to creating bills of materials to scheduling product

The PC Revolution (1975 - 1981)

Alta 8800, the first microcomputer, is announced in 1975
Apple Computer, headed by Steve Jobs and Steve Wozniak, follows soon after
1981, IBM and Microsoft team up and release "PC" which uses Microsoft DOS as its operating system

Client-Server (mid - 1980s)

client-server network architecture was introduced to allow users to log in to the LAN from their PC (the client) by connecting to a powerful computer called a "server," which would then grant them rights to different resources on the network such as the shared files and a printer on the server.
This spurred software companies to begin developing applications that allow multiple users to access the same data at the same time
The first ERP (Enterprise Resource Planning) was developed to run to the client-server architecture
- An ERP system is a software application with a centralized database that can be used to run a company's entire business.
German's SAP lead the way of ERP by integrating accounting, finance, inventory, human resources, and many more together

The World Wide Web & E-Commerce (Invented in 1969)

The internet was first invented in 1969 but was confined to use by universities, government agencies, and researchers
the first e-mail messages were sent in the early 1970s, but companies who wanted to expand their LAN-based email started hooking up to the internet in the 1980s.
In 1989, Tim Berners-Lee developed a simpler way for researchers to share information over the network t CERN laboratories, a concept he called the World Wide Web. This invention became the launching point for businesses to share information about themselves using web browsers and grab domain names to create websites.
In 1991, the National Science Foundation lifted restrictions on its commercial use
In 1995, eBay and 1994, Amazon established the new digital marketplace and led to the dot-com boom through the 1990s and then the dot-com bust in 2000
As more companies connected to the internet, the digital world became a more dangerous place with computer viruses now being able to spread with tremendous speed via the internet.

Disintermediation - the process of replacing a middleman in a transaction
