A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer

All electronic components inside the computer require electric power to power to work.

Random-access memory is a form of computer data storage.  In contrast, with other direct-access data storage media such as hard disks, CD-RWs, DVD-RWs, the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement.

So it means that every program when it starts it goes to RAM and working there

A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output operations specified by the instructions.

The more powerful is CPU the faster computers work.

A motherboard is the main printed circuit board (PCB) found in computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals.

It means that the mother board is the main part of the computer.

A hard disk drive (HDD), hard disk, hard drive or fixed disk is a data storage device used for storing and retrieving digital information using one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. The platters are paired with magnetic heads arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. HDDs are a type of non-volatile memory, retaining stored data even when powered off.

There are two kinds of hard drives 2.5 it is for the laptop and the other one 3.5 for desktop
