A Strong Background in Computer Technology Will Benefit Future Engineers Computer technology has advanced dramatically over the past ten years. Technology has advanced from computers the size of a room that can only perform one particular task, to personal computers (PC’s) that will fit on a desk and perform multiple tasks. Understanding computers and their programs and being able to apply that knowledge is very important in today’s workplace. Engineering is a field that requires an extensive background in computer technology. Future engineers will benefit dramatically from having a strong background in computer technology. In order to understand why computers are important, we have to understand what a computer is and what it does. A computer is a device capable of performing a series of calculations or logical operations without human intervention. The computer is characterized by the number and complexity of operations it can perform and by its ability to process, store, and retrieve data (“Computers” 1). The development of computers began in the 19th century by British mathematician Charles Babbage (Eadie 3). Babbage designed, but did not build, a mechanical digital device capable of processing information as a modern computer does (4). In 1930 American scientist Vannevar Bush built a mechanically operated device, called a differential analyzer (4). It was the first general-purpose analog computer. Analog computers will be discussed later in this paper. The first information-processing digital computer actually built was the Automatic Sequence Controlled Calculator, or Mark I computer (4). Completed in 1944, this electromechanical device was designed by American engineer Howard Aiken (5). In 1946 the Electronic Numerical Integrator and Computer, or ENIAC, was put into operation (5). Using thousands of electron tubes, it was the first electronic digital computer. In the late 1950s transistors replaced electron tubes in computers, allowing a reduction in the size and power consumption of computer components (5). In the 1960s hybrid computers were tried that connected analog computers to digital ones. Later integrated circuits were developed that allowed further reduction in component size and increase in reliability. The introduction of a relatively easy to use PC in 1981 began a period in the rapid growth of the computer industry. The computer industry is still thriving today with the introduction of faster processors such as the Pentium II and now the Pentium III, high tech printers, scanners, and of course the Internet. There are two types of computers, analog and digital. An analog computer is designed to process data in which the variable quantities vary continuously; it translates the relationships between the variables of a problem into analogous relationships between electrical quantities, such as current and voltage, and solves the original problem by solving the equivalent problem, or analog, that is set up in its electrical circuits (Eadie 9). Because of this feature, analog computers are useful in the simulation and evaluation of certain complex situations. Analog computers do not play a role in engineering today, but without the introduction of analog computers PC’s would not be what they are today. Digital computers are referred to as PC’s. PC’s are used everyday in the workplace, at school, and at home. Many programs can be accessed and loaded into a digital computer. Most technical jobs, including engineering, require experience and understanding of PC’s and the programs that are related to the field in which the PC is being used. A digital computer is designed to process data in numerical form; its circuits perform mathematical operations of addition, subtraction, multiplication, and division. The numbers operated on by a digital computer are expressed in the binary system. Binary digits, which are also known as bits, are 0 and 1, so that 0, 1, 10, 11, 100, 101, etc. correspond to 0, 1, 2, 3, 4, 5, etc. A series of eight bits, called a “byte”, is
