One file about you would pertain to your skills and abilities, another file to your income text status, another to your home, office address, telephone number and another to your annual performance ratings.

An information system can be defined technically as a set of interrelated components that collect or retrieve, process, store, and distribute information to support decision making and control in an organization. In addition to supporting decision making, coordination, and control, information systems may also help managers and workers analyze problems, visualize complex subjects, and create new products.
Three activities in an information system produce the information that organizations need to make decisions, control operations, analyze problems, and create new products or services. These activities are input, processing, and output. Input captures or collects raw data from within the organization or from its external environment. Processing converts this raw input into a more meaningful form. Output transfers the processed information to the people who will use it or to the activities for which it will be used. Information systems also require feedback, which is output that is returned to appropriate members of the organization to help them evaluate or correct the input stage.

Ninth week learnt about History of the Internet

When the original conceptual foundation of the Internet was laid back in the 50s, no one had the slightest idea of how far this project would go. At those insecure post-war times of alienation and deepening political division, the vision of the Internet as we see it today, was only a matter of science fiction dreaming. Starting as a military project in the United States, it quickly became very popular in several other countries. Now, several decades later, with the spread of the democratic lifestyle and the amazing technological progress, we all witness the existence of a parallel world of unlimited communication possibilities that occupies an increasing part of our daily routine with the sole purpose of facilitating our lives.

History of the Internet:

 Mid 1960:   Papers on “Packet Switching” emerge.

 End 1969s:   ARPA sponsors the development of a packet-switching network, called the

 ARPANET. First four nodes are UCLA, SRI, U. Utah, UCSB.

  1974:   The TCP/IP protocols and model are being proposed by Cerf/Kahn. 

  1980:   IPv4 is introduced.

  1983:   ARPANET adopts TCP/IP. At this time, the ARPANET has 200 routers. 

  1984:   NSF funds a TCP/IP based backbone network. This   backbone grows into the NSFNET,

which becomes the successor of the ARPANET.

 1995:   NSF stops funding of NSFNET. The Internet is completely commercial. 

Time line of the Internet:
