CSI 1101: Introduction to Computers

Introduction
We live in the middle of an information revolution. Computers and related technologies impact on our everyday lives, affecting the way we work, study and play. Consequently, computer literacy is becoming increasingly more valuable, if not essential, in the workplace and at home. This course encourages the development of basic computer skills, but involves much more than that. It explores issues relating to the world of computing in general; where it has come from and where it is going, how computers contribute to people becoming more productive, and some of the problems that computers have caused. Lectures will apply to a wide range of common computers, and will be supplemented with laboratory exercises that provide concrete examples of the general principles discussed. CSI 1101 is intended to prepare people to work in a society where information is viewed as an important asset.

Objectives
By the end of the course students will be able to:

• Name the major hardware components of a computer and explain their functions.
• Explain what computer software is, how it is developed, and the difference between system software and application software.
• List popular computer applications and the problems they can solve.
• Describe basic features and different kinds of programming languages.
• Explain networking fundamentals and basic features of the Internet and the World Wide Web.
• Discuss issues of human-computer interaction, computer security and privacy, and the ethics of computer use.
