Installing and maintaining computer hardware

For unit 14 on my college course i had to look at a given machine list the parts and suggest an upgrade plan and explain why these parts were chosen and list some alternative parts and explain why they weren't used

​

For Unit 14 i had to take a look at phones and PC parts and compare them and decide which is better in perfomance and price and after this i hd to look at the pre-existing components in a computer and using the knowledge from Unit 2 and what we were taught on this one suggest and upgrade plan to the clients requirements. As well as suggesting components that can be used we had to list components and why they didn't work  wether it was compatability or price. And learn about installing components into computers and the saftey that should be taken when maintaining a computer.
