An employee would insert the punched-cards into the machine. Then, this giant would print out an invoice with all the trimmings. Needless to say, this was in the mid 70s state-of-the-art technology: the era of mainframe computers (mostly used for transaction processing) roughly covering the late 50s through the 70s. A computer professional would probably smile at the informal way I associate this device to the mainframe era, but at that time it was an impressive technology only larger businesses could afford.
This IBM machine was known as the “Card-Programmed Electronic Calculators (CPC). Mainframe computers would soon be followed by mini, micro and personal workstations also known as personal computers.
2. PC Era IBM underestimated the fact that by the mid 90s, personal workstations would usher in Personal Computer that eventually would replace the typewriter. Some of us probably remember the Commodore PET, the first successfully marketed personal computer introduced in 1977. The predecessor to IBM AS/400, System/38 was first made available in August 1979. It was marketed as a minicomputer for general business and department use. It was sold alongside three other product lines, each with a different architecture not compatible with each other. Digital Equipment Corporation used this IBM weakness to expand. Digital Equipment was acquired by Compaq in 1998 which then merged with Hewlett Packard in 2002. In the meanwhile Paul Allen and Bill Gates had founded ”Micro-Soft,” the combination of microcomputer and software, which became a US$ 42 billion corporation. 3. Internet era Internet service provider (ISPs) began to emerge in the late 1980s and early 1990s. CompuServe (my first email address) was a service provider founded in 1969. CompuServe was the first major commercial online service in the United States that became a leading worldwide internet service provider. In 1998 CompuServe became a subsidiary of America Online Inc. (AOL). Internet has become a global system of interconnected computer networks to serve billions of users worldwide. Since its email commercial start, Internet technology has added: instant messaging, Voice over Internet Protocol (VoIP) with services such as Skype, two ways interactive video calls and finally the World Wide Web including discussions forums, online shopping, blogs and more recently social networks. 4. Internet broadband and the World Wide Web era Broadband Internet access or broadband is a high-speed internet access that replaced the awkward dial-up “modus operandi” some of us remember. Dial-up bit rates varied from 33 to 64 kbit/s and required a telephone line. Broadband started supplying higher bit rates with the crucial advantage of not disrupting regular phone lines. It also provides a continuous “always on” connection. Then came the World Wide Web, a system of interlinked hypertext documents accessed via the Internet. Broadband supports a much faster World Wide Web browsing experience, faster downloading/uploading of information, video telephony, computing mobility with VPNs (virtual private networks) and online gaming experience. Next week, we will post the second half of this two-part series with the last three reasons why IT should become the technological beacon of a social enterprise 2.0 transformation. In the meanwhile I wish you a very pleasant rest and a wonderful weekend.
