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, st ore, and retrieve data (â€Å"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 comput...

This is especially true in a market such as computer parts where the lifetime of a product is short. Companies are always searching for a way to create products faster and more efficiently. One tool that allows companies to cut the time between a product concept to launching the product is rapid prototyping. The rapid prototyping (RP) process generally consists of seven steps. These steps are listed below: 1. The RP equipment imports model data from a CAD/CAM file 2. The RP equipment creates a cross-section of the model using different techniques 3. The RP equipment uses the cross-section to build up the model layer-by-layer 4. The process is repeated until the model is complete 5. The model is removed from the RP equipment 6. Depending on the technology used, some models need to cure in ultraviolet ovens 7. Models are then machined to their final finish Rapid prototyping allows models to be created within hours. The hand carved models of the past could take weeks, even months to complete. Currently RP is only used for prototyping. Many people hope that someday it will replace the traditional production line. Discussion The declining cost of computers has changed the way a factory works. An increase in use of computers has aided in the advancement of computer-related areas such as computer-aided design (CAD), computer-aided Manufacturing (CAM) and Computer Numerical Control (CNC).

Free Essays on Computer Metaphors and Their Meanings In the poem â€Å"Marks† by Linda Pastan, the speaker resents the way she is treated by the members of her family. Linda feels dissatisfied because she does not feel that her family respects her enough as a mother. Linda wrote the poem †Marks,† whose main theme was the metaphor of school grades. The poem does a great job of showing Linda’s true feelings, as well as the possible idea of her dropping out. I think that Linda chose this metaphor to describe her family because she feels that her family is judging and grading her performance at home. According to the poem, Linda does not feel appreciated by her family. Instead she feels like she is a servant or a maid to them. The quote, â€Å"My husband gives me an A for last night’s supper, an incomplete for my ironing, a B+ in bed.† (Pastan) makes Linda feel like she is just being used for her services, and not loved for being a wonderful wife. The remark by her son has enough power to make any parent feel discouraged. The quote, â€Å"My son says I am an average mother, but if I put my mind to it I can improve,† (Pastan) can really upset parents, especially when they try their hardest to provide the best for their children. All the criticism that Linda faces causes her to want to stop being a mother. I think the reason she is saying this at the end of the poem is because she wants her family to realize how vital she is to the family, and that the jobs Linda does are jobs no one else can do. The metaphor used is an excellent way to put her thoughts into writing. It is effective because it shows the lack of care by her family. Metaphors, when used appropriately, are a great way to spice up a paper or essay. Metaphors provide that descriptive edge that many papers lack, and they keep the reader focused and interested. Metaphors take a particular item or topic, and compare that item or topic to something completely different. For exam...
