To use your knowledge of modern computing components to select the appropriate components to create a number of computers.
Identify the cost of building a computer using components bought individually from a store. You should create a Bill of Materials (including URLs to an online shop) including the cost of the individual components and the total cost for your system.
You should ensure that the components are compatible, and include a case.
You should select the components to match each of the following profiles and budgets.
a) A server computer (you should ensure you use ECC memory) (max $2200) to be used in a doctor's clinic, serving multiple doctors.
b) A computer (max $650) that would be used in the doctor's clinic by doctors and receptionists.
c) A gaming computer (max $1200).
You should briefly describe why the choices you have made would be appropriate for each of the computers. The gaming computer should have the ability to use SLI or CrossFire. Ensure that the feature is used in your system.
Identify an appropriate hardware backup solution for the server computer, as well as a process to ensure that the backups are performed regularly, and are secure.
Identify possible risks associated with doing backups and how your strategy overcomes them.

The server can be backed up regularly and this helps to secure the files and application data residing in the server computer. Automatic backup can be configured on the windows server and the files and the application data that is required to be backed up regularly is selected. The backup can be saved in the local server or exported to the cloud platform for making the system disaster proof. The windows server has a smart algorithm which automatically deletes the old backup files and when the storage location becomes full. One time backup of the system can also be created by using the Wbadmin or the windows power shell option . The regular backup of the system makes the system to perform from any disaster and recover the system to the last backed up state.
Media Failure- If the media that is used for backup such as hard drive or data tapes gets corrupted then the whole data backed up in the media gets lost and causes a huge loss for the organization. The backup media can also be get stolen for illegal use and thus the media is required to be kept in a secured place and should be treated at a regular interval of time for eliminating the risk.
Human Error- human mistake is likely the most productive reason for reinforcement disappointments. For instance, if tapes are dishonorably put away between utilizations, is the subsequent disappointment a media disappointment or a human mistake . As a rule there's a noteworthy part of human mistake in any reinforcement disappointment.
The best defend against human mistake in reinforcements is to prepare those included to take after prescribed procedures. Ensure that the general population performing reinforcements and reestablishes see precisely. The creation of an automatic backup can used for eliminating the risk and increase the efficiency of the backup system.
Hardware Failure- The old media device should not be used because the read write head can move out the alignment and may result in improper reading and writing of data. The hardware device used for backup must be checked regularly and maintained for eliminating error in the backup.
