It begins with a discussion of algorithms, how they are developed, and how they may be compared. We also
introduce a formal model of computation. After reading this chapter you will have a basic understanding of
algorithm development and will be able to develop algorithms to solve simple problems.
After studying algorithms, the text will focus on the basics of computer hardware. In this chapter you will
learn what the major components of the computer are and how they work together. You will also learn about the
binary number system and see how it can be used to encode information at the hardware level.
The next two chapters will focus on programming. We will first study software in general and discuss
how high-level languages can be constructed to provide models in which algorithms can be expressed, and
ultimately expressed in a way that the hardware can work with. In the next chapter we will focus on programming
using the programming language Java. The goal of this chapter is not to make you an expert programmer,
but instead to introduce you to the basics of programming using a language that is readily available and
in wide use.
After learning the fundamentals of programming we will focus on operating systems, networking, and
databases.
