1. Installation and maintenance hardware.
By Bartosz cichy

2. PC Benefits of installation a new hard disk (HDD):
much faster saving of data
bigger storage
no errors in system
unlimited data access
Benefits of maintaining an old hard disk (HDD):
checking hard disk drive with applications, such as CrystalDiscInfo, or HDDscan
when the computer is maintained regularly then there will be no damages and it will work longer
better performance of computer system

3. Benefits of installing a new graphic processing unit (GPU):
better display resolution
faster landing of images
speed up a PC
no problems with animations
Benefits of maintaining an old graphic processing unit (GPU):
it does not overheat
better ventilation
it will work longer
it does not make any noise when it is clean

4. Laptop Benefits of installing a new motherboard:
ability of installing new and better hardware
faster performance of a laptop
faster to replace the motherboard
Benefits of maintaining an old motherboard:
when slots are in a good condition there are no problems with connection components to a motherboard
it is cheaper to maintain current motherboard
the replacement will not be required for a long time
Better performance

5. Benefits of installing a new central processing unit (CPU):
energy saving
better and faster performance of the laptop
less risk of errors
the laptop is more reliable
Benefits of maintaining an old central processing unit (CPU):
stay cool, does not overheat
to keep the CPU cool you can use CPU Cooler to reduce the heat

6. Implication of installing
It takes more money than maintenance as the company will have to pay for expensive components, where in total there might be more than 20 of them.
Required training or a good knowledge about computer construction. The company will have to pay to train their employees, unfortunately training is not chap and can take a lot of time.
Hardware must be compatible because otherwise it will not work (hardware must cooperate with the software).
Before buying new hardware you should check if you need one because you might not need it at all, otherwise you will see disadvantages after installation. Some of the current components don’t need to be replaced. All they need is to be cleaned up to work well again.

7. Implication of maintenance
You need special tools to perform the maintenance, for example: compressed air which is used to clean keyboards and all spaces that are hard to reach and clean, such as CPU socket or RAM slots.
Health and safety rules, you need to make sure you work in the safe conditions. It means that you need to wear suitable clothes, glasses to protect your eyes, anti static hand wrist to make sure you’re safe while taking the components out of the machine. You must always keep work area clean and tidy.
You need to make sure you don’t break any of the components as you will have to pay for a new one, as it’s your fault not the company.

8. Impact to the business
Time spent: business must take the time for both, installation and maintenance. Even thought installation will not take a lot of time, staff training afterwards will. To teach the staff how to use new systems and machines might take up to few weeks. Maintenance might take a lot of time as all the components will have to be cleaned up carefully. The need to of being careful always take much more time.
Costs: the company need to spend more money on new hardware, which is more expensive than maintenance. Some of the components are very expensive, for example new graphics card will cost more than £800 (per one) and the company will need to buy at least 5 of them. Unfortunately maintenance will not speed up the GPU much, that’s why the company will actually have to buy new ones.
Compatibility issues: if the hardware is not compatible then it will not be recognized by the system and it will not work. All of the components must cooperate with each other. There is no sense in buying random expensive components if at the end of the day they won’t work together. That’s why the knowledge is very essential to avoid making any mistakes when buying new components.
Usability: if the user does not know the new version of the hardware, it will be difficult to use. This is why staff training will be a must so that all the staff will learn how to use it.
