The document discusses the main parts of a computer including the motherboard, which is the central circuit board that runs the system; the processor, which handles data flow; the hard disk drive, which uses magnetic surfaces to store data on rotating platters; and random-access memory (RAM), which allows integrated circuits to access stored data in any order.

1. Parts of the Computer By: Jon Mari T. Maglanoc

2. Motherboard Motherboard - is the central printed circuit board (PCB) in some complex electronic systems, such as modern personal computers

3. Processor Processor – brain of the computer that handles the flow of all data.

4. Hard Disk Drive Hard Disk Drive[1] (often shortened as "hard disk"[2], "hard drive"[3], or "HDD"), - is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces.

5. Random-access Memory Random-access memory (usually known by its acronym, RAM) - is a form of computer data storage. Today, it takes the form of integrated circuits that allow stored data to be accessed in any order.
