WHAT WE FOUND We found the following parts of the computer:  RAM  Hard disk drive  Mother board  Power supply unit  Fan unit

HARD DISK DRIVE DRIVE It is abbreviated as HDD. It is a data storage device used for storing and retrieving digital information. It uses one or more rapidly rotating disks coated with magnetic material. Although it may seem the hard disk drive (often shortened to "hard drive") and the hard disk are not the same thing, they are packaged as a unit and so either term is sometimes used to refer to the whole unit.

MOTHER BOARD A Motherboard holds and allows communication between many of the most important electronic components of a system, such as the central processing unit (CPU), memory, etc. A Motherboard contains significant sub-systems such as the processor and other components. Motherboard specifically refers to a PCB with expansion capability and as the name suggests, this board is often referred to as the "mother" of all components attached to it, which often include sound cards, video cards, network cards, hard drives or other forms of storage.

FAN UNIT The fan unit helps cool down the computer when it is heating up. It automatically switches on when the temperature sensor senses a certain level of heat. It is crucial to making sure the computer doesn't heat and/or eventually catch on fire. Without the fan, all computers can be dangerous to humans.

POWER SUPPLY UNIT A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use a switched-mode power supply. Some power supplies have a manual selector for input voltage, while others automatically adapt to the supply voltage.

RAM The RAM (Random-access memory) is a form of computer data storage. A random-access memory device allows data items to be accessed (read or written) in almost the same amount of time irrespective of the physical location of data inside the memory Today, random-access memory takes the form of integrated circuits. where stored information is lost if power is turned off. Other types of memory exist that allow random access for read operations, but either do not allow write operations or have limitations on them. These include most types of ROM and others.
