I am going to show the evidence behind the solution I have made. I am going to show how I am going to achieve what I said in specification. I am going to give 2 options, and will show the pros and cons of each. One might be better than the other. I am going to show six different sections for each part of the implementation. Hardware First of all, my client will need a computer. There are many options within this. There are six options: – Monitors Processors, Printers, RAM (Memory), Hard Drive. Monitor A monitor is the screen. This is the visual part of a computer.
A monitor is a component with a screen that is used for viewing data at a computer terminal (video display terminal or VDT). Therefore, a monitor is needed to see the visual effects of what you are doing. The video output of the computer generates the image. No computer is complete without it. I am going to show the advantages and disadvantages of using TFT and then I will do the same with CRT. At the end I will conclude which will be the best option for my client, Bob. 1. He can choose a TFT. This is a flat screen monitor. It is the newer version of the two.
The pros of choosing TFT are: It uses less space, They are modern, and therefore look more professional, They may also have better resolution, Faster FPS (i. e. frames per second), Don’t give off a glare, Give off less heat, Very compact and tight, Uses less power, No geometric distortion, Rugged, Very little or no flickering, depending on backlight, Larger in screen size. The cons of choosing TFT are: They are more expensive, Contrast ratio is low, Lots of colour, saturation, contrast and brightness varies if viewed from an angle, sometimes even when viewing it from the intended posture.
Brightness distortion if the backlight is uneven, Slow response times, causing smearing and ghost artefacts, Input lag, Hard to see the screen if the sun is shining on it and from an angle it is hard to view. 2. On the other hand, my client could choose CRT. This is a curved screen monitor. It is the older version of the two. The pros of choosing CRT are: It is relatively cheap, High contrast ratio, Additive colour is excellent, Hardly no contrast, colour, brightness and saturation distortion, No input lag, Reliable, proven display technology, The view does not change whatever angle you look at it from. Nonetheless, there are also many cons for CRT.
Gives off lots of heat. I would advice Bob to choose TFT, as although it is more expensive, it makes up for it through reliability and it is also more modern. Processor A processor is a personal computer known as a central processing unit (or CPU). A processor is a program that translates a different program into a form that is accepted by the computer being used.
Without it nothing will be able to run. I am going to compare and choose one of either AMD or Intel. 1. Bob can choose Advanced Micro Devices (AMD). The pros of choosing AMD are: It is cheaper than its alternative. The cons of choosing AMD are: Bad performance. Unreliable. 2. On the other hand Bob could choose an Intel processor. The pros of choosing an Intel processor are: Good performance, it is fast. Lasts for longer and is more reliable. The cons of choosing Intel are: It is more expensive. Intel is more expensive, but I would Bob to choose this as it is better overall, and worth the long term investment.
Printers There are two main types of printers that Bob can choose from. They are inkjet and laser. 1. Bob could choose inkjet. The pros of choosing inkjet would be: Cheap. Fast when printing small amounts. Allows various paper types. The cons of choosing Inkjet are:Expensive to run. Slow when printing many documents. Unreliable. The quality and durability depends on ink type, ink quality and paper type. 2. On the other hand Bob could choose a laser printer. The pros of choosing a laser printer are: Generally has a faster printing rate. Has very good printing quality.
Produce very little sound. Have good features, like self-printing which means the user does not have to supervise the printing. The cons of choosing a laser printer are: Expensive. Take up lots of space. Only one printer can be printed at a time. Reliable but costly to repair. I would advise Bob to choose Laser printer as overall it is better. Even though it is more expensive now, it would be cheaper in the long term. RAM Random Access Memory (RAM) is a form of computer storage. All data is stored here. 1. Bob could choose 512 MB. The pros of choosing it are:
It would be cheap. The cons of choosing it are: It has a small memory. 2. Bob could also choose 1GB. The pros of choosing it are: It has a large memory. The cons of choosing it are: It is expensive. I would tell Bob to get 1GB as he needs it. It may cost more but it is necessary. Hard Disk Drive A hard disk drive is a non-volatile storage device. 1. Bob could choose a SATA Hard Disk Drive, the pros of which would be: They have a fast running speed (of about 3 GB/s). It also has Native Command Queuing which makes it more efficient. They also have Port Multipliers.
