Hardware

The system requires certain pieces of hardware in order to run properly. These include the following areas of hardware:

I have used Excel to create the project. For the actual system for the party planners I would specify the use of a more up-to-date PC system such as a dell vostro 1525 with an Intel core i5 processor system running Windows 7 as the quality of the output will be better and the planner may need to run several versions at the same time.

A monitor is required for the system as an output device to display images. CRT (Cathode Ray Tube) monitors are big but have strong screens with glass screens that don’t get damaged easily. However, they make quite a lot of heat and noise. They also take up a lot of space due to their size. The more common monitors are the thin TFT (Thin Film Transistors) monitors that take up less space as they are smaller than CRT monitors.

They also make less heat and noise than them, but these monitors are more sensitive and a sharp object can permanently damage the screen. Even the colour and contrast isn’t as good, which has dull pictures. For JJ party Planners, the best monitor would be a TFT because it takes up less space and makes less noise. The sales assistants won’t damage the screens or need high quality pictures so a TFT monitor would be fine as it doesn’t cost too much now.

The system is more than fast enough, since the formulae in my spreadsheet are quite simple and don't need a lot of computer power. The data used will only take up about 1 GB so the disk space of 320 GB on the Dell is more than enough for the staff at JJ Party planner so save details and other information on the system.

In order for the staff at JJ Party Planners to print invoices, receipts and reports, a printer will be needed. A laser printer can be used for this because their quality and speed is better than ink-jet printers. Their toners last longer than ink cartridges, as well. On the other hand, toners and colour laser printers are more expensive as is the cost if it needs repairing. Ink-jet printers are cheaper than laser but don’t have the quality of laser printers and smudge when they are wet. They are also louder, slower and more expensive per page. This is because cartridges need to be replaced more because they dry out when they aren’t used. Ink-jet printers are more suitable to be used at a home because the quality doesn’t have to be great and not a lot of pages are printed.

Therefore, laser printers are more useful for JJ Party Planner. I have researched several printers and have chosen a Lexmark 201 from Dabs Computer Systems. The Lexmark 201 printer produces good quality colour images in a short time; although a commercial system would possibly find it too slow. In that situation a laser printer would give greater speed, but colour lasers are very expensive to run.

The capacity of the RAM (Random Access Memory) is also important because it holds temporary data that is lost when the computer switches off. The system can have a RAM of 1GB or ...

Here's what a star student thought of this essay

The spelling and grammar is close to perfect throughout; the only problems are a few misplaced apostrophes and suchlike, but these are minor issues and communication is of an overall high standard. You clearly show and explain your points without the piece being hard or awkward to read.

You have used technical terms correctly and appropriately. You have shown the need to have certain hardware and detailed its use in the system you are describing for the company. You have shown the advantages and disadvantages of your chosen components and an alternative, and then weighed up each part and chosen the most appropriate component and software for the job.

A good piece of work to identify the best hardware and software needed for your chosen company. You have shown the requirements for their system and then proceeded to show a few examples of suitable software that will fulfil the task. You could go into a little bit more detail on a few points, such as the opening paragraph, when you say “quality of the output will be better.” How and why would the output be better?
