Computer Hardware Components, Languages, Algorithms, and Program Development

Session two will explain the concept of the von Neumann computer and the difference between a von Neumann computer and a supercomputer. You will know what is meant by input/output (I/O) and its significance. Also, the difference between original and previously stored data or information and the difference between primary and secondary memory as well as the four characteristics of secondary memory devices. Be able to identify the four basic components of a typical computer and the three basic components of a CPU as well as how the fetch and execute cycle works. You will be able to identify the relationship between bits, bytes, and words and the many types of digital electronic computers. Understand and appreciate the significance of software utilities for maintaining hardware. You will be able to discern the reasons why programming languages are necessary to communicate with computers. Also, know the definition of semantics and how it relates to computer programs and syntax and how it relates to computer programs. You will identify the five generations of the program language continuum. Next, understand the differences between an assembler, an interpreter, and a compiler as well as how scripting relates to programming in general. You will know the steps necessary to build a computer program and the four criteria for analyzing a program's quality. Be able to identify the steps taken to test a program after its initial creation and appreciate the amount of time and effort it takes to complete a large, intricate computer language. Finally, understand how easy-to-use software can create other, more complicated forms of software such as HTML.
