General Computer Question 27: What is the  system development cycle?

Answer:   Today, the development of a computer system is generally based on a  systems development cycle model. In such a model, the systems development process is broken down into a number of manageable phases. By breaking the task down into smaller units, the systems analyst can receive feedback at each stage of development and can thus assure the effectiveness and success of the system. This systems development cycle approach also reduces the cost of systems development because the greatest expenditures are made during the later phases of the cycle (the earlier stages mostly involve planning). Although individual organizations may break the systems development process down differently, the best approach is to break the task down into small, manageable units. For example, we could break the systems development task down into the following five phases:

They provide skills that will allow you to enter the job market for the first time or improve your chances for promotion in a job that you already have.

A number of universities now offer an introductory computer course that must be taken by all students. These courses are designed to introduce students to basic computing concepts, such as those presented in this text. In addition, these courses often provide hands-on tryouts of the most popular computer
