Hard Drives/SSD
A hard drive stores all the software, documents, photos and videos on a metal disc. Without this, the computer wouldn’t work, as you would need to download software in the computer to make it work. These days technicians are making new, better, smaller and more efficient hard drives(SSD).
SSD’s are solid state drives, which have no moving parts in them. They are much smaller, lighter and more effective however, because of their abilities; they are sufficiently more expensive than normal hard drives.
SSD
These are becoming more used as they are much lighter than hard drives and store just about as much memory as them. The new MacBook Air has on of these, that comtributes to its name, but as before, they are still more expensive.
Hard Drive
These are what most computers have in them because they can store a lot of memory (depending of the size and the manufacturer) however, this is what weighs down your comuter a bit.
Floppy Disk
These are what people used to use, some were seventy pounds and were only 64megabites,if you think of a USB for 2gb cost a fiver!
CPU (Central Processing Unit)
The Central Processing Unit (CPU), contains a part of the computer called the microprocessor. The microprocessor is the brain of all the computers operations and the whole performance of hardware and software relies on this one part of the computer. This is arguably the most important part of the computer. There are two common types of CPU: 64bit and 32bit, however it depends on the manufacturer.
