Title: Module 10 Introduction
Course: CGS 1560 Microcomputer Operating Systems > Section: Module 10 - Networking

The advent of mainframe computers created a need to have groups of people communicating with the computer at the same time. This was accomplished through the use of what were called dumb terminals, these were devices that did not process data they simply communicated keystrokes to and from the mainframe and video from the mainframe. This was known as central processing or centralized computing because the mainframe housed the central processing unit and did all of the work.

As the technology to develop networks began to emerge, there was a paradigm shift toward distributed computing. PC Magazine’s Encyclopedia describes distributed computing as, “The use of multiple computers in an enterprise rather than one centralized system. This use of the term was coined in the late 1970s when minicomputers were first installed in departments throughout a company instead of deploying terminals to a mainframe.” Businesses quickly adapted to this form of computing and much advancement was made in this area.

Networking allowed users to share resources such as printers, folders and applications. This efficient sharing of resources by linking computers together became an integral function of the operating system. An understanding of how this is accomplished allows you to more effectively accomplish tasks required in today’s workplace.

Instructional Goal

The purpose of this module is to introduce the basic concepts of networking to the learner.
