Using Hardware

Introduction

Using Hardware- Evaluation I used a Mouse to control and design everything, a Keyboard for writing important information concerning my customers. I also typed numbers with my Keyboard, and numbers are very important to use for Excel, concerning formulas. The Desktop was the main important thing, where my Travel Agency took place, and where everything was stored. I used a Canon Inkjet printer, to print out information for my Travel Agency, like drafts. The reason I used a Canon inkjet printer was because it was easy to use, low cost, and high quality of output. Another output device I used was a monitor, this helped a lot so that I can see what changes I need to make and just visually analyze my Travel Agent. Using a keyboard to type while looking at the screen, is much faster than writing with other properties, such as pen and paper. I could have used pen and paper, but I also wanted a safer way for my data, example- stored more safely on the computer/ USB. Writing in Microsoft Word rather than pen and paper, is a higher advantage because I can also use spelling and grammar checker. The disadvantage of using a computer to do my Travel Agent booking System is that it might take a while, and while staring at the computer screen for too long, electromagnetic rays from the monitor can damage your eyes. ...read more.

For my process, a Desktop Computer Tower is designed to keep all your information in the hard drive and does calculations very fast, such as a calculator or a program, the same as Microsoft Excel. The Desktop Computer Tower's purpose is simply to keep the whole process running, and it is what makes the computer work. Everything is connected to the Desktop Computer Tower which also proves that it is very important and one of the main hardware's. The Desktop Computer Tower is good at entertaining the user, because it is the computer as itself and many people enjoy computers. It also helps with a variety of options that you need. There are also bad points about it, such as speed which depends on the GHz but it would cost more to have a higher amount. For the output, a monitor is designed to visually show a user what is happening inside the Desktop Computer Tower in a form that the user can understand. The monitors' purpose is just to basically show everything a user is doing/ changing. A monitor is good at showing you everything, although there can be lag (freezing) which is irritating and annoying. There are also screen waves that can harm your eyes gradually. A printer is designed to print out what you have viewed on your monitor screen, onto paper. This isn't one of the important things, although it is quite helpful if you are not carrying a USB stick or would want to give out information physically. ...read more.

Conclusion

onto paper and that is why it is called an Inkjet printer. The good things about an Inkjet Printer are that they are quieter while doing the printing process, they also print finer and smoother details, and are widely available. Comparing this to laser printers, they have the advantage of practically no warm up time at all, and lower cost per page. Another good thing about Inkjet Printers is that the inkjet cartridges can be refilled, and this method is more cost effective as to buying a new cartridge each time one is finished. The things that an Inkjet Printer is not so good at doing are, the ink is often very expensive to purchase, the lifetime of inkjet is limited and they will eventually fade and the colour quality might change. The ink used in Inkjet Printers is water-soluble, therefore you must avoid the slightest drop of water on a printed-paper, because it can cause colour mix and it will be blurred/ hard to read. I could have also used a Dot-Matrix printer, which is designed to draw letters out of a dot matrix. The way it does this is by a small ink-soaked cloth ribbon on paper, creating 'dots', which is similar to a typewriter. The good thing about it is, as the ink is running out, the printing gradually fades rather than stopping in the middle of a page. A few not so good points about a Dot-Matrix Printer are, they are usually noisy, very low speed compared to a Laser Printer, and limited printing quality. ?? ?? ?? ??
