Life, Mood & Reality Ajiro Ndi

you will explore the following stages of the system life cycle process:

Analysis Stage: This includes methods for analyzing the current system, identifying its inputs, outputs, and processing methods. It also covers the hardware and software requirements for the new system.

Design Stage: This involves designing file structures, input and output formats, data capture forms, screen and report layouts, and validation routines.

Development and Testing Stage: This stage covers test strategies and plans, as well as the use of test data, including live data.

Implementation Stage: This stage includes direct changeover, parallel running, pilot running, and phased implementation methods.

Documentation Stage: This stage involves creating technical and user documentation for the new system.

Evaluation Stage: Finally, this stage includes evaluating the new solution and comparing it to the original system.

We all need to pay attention to this.

The introduction of microprocessor-controlled devices into our everyday lives has had a profound effect in a number of ways. Some of these are positive and some are negative. This chapter will consider the effects of devices used in the home and elsewhere, and how they have changed how we live.

We will also consider the health risks posed by prolonged use of
computers at home and at work.

Most computer systems are now connected in some way to form a
network. This ranges from a basic home network of only a few devices to very large networks, often set up to share resources, such as printers or software. The largest network is the internet itself.
