Answer:
Here are some :) (sorry if there are too many)
Step-by-step explanation:
RAM (Random Access Memory): It's a fast-access memory that is cleared when the computer is powered-down. RAM attaches directly to the motherboard, and is used to store programs that are currently running.
Video Card/GPU (Graphics Processing Unit): It's a specialized processor originally designed to accelerate graphics rendering.
Sound Card: USB sound "cards" are external devices that plug into the computer via USB.
Storage: SSD (Solid State Drive): It is a data storage device that uses solid-state memory to store persistent data.
HDD (Hard Disk Drive): It is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces. Just about every new computer comes with a hard disk these days unless it comes with a new solid-state drive.
CPU (Central Processing Unit/ sometimes just called a processor) It's a machine that can execute computer programs, and sometimes called the brain of the computer.
Motherboard: The motherboard is the body or mainframe of the computer, through which all other components interface. It is the central circuit board making up a complex electronic system.
Firmware: Firmware is loaded from the Read only memory (ROM) run from the Basic Input-Output System (BIOS). It is a computer program that is embedded in a hardware device, for example a microcontroller.
Power Supply: The power supply as its name might suggest is the device that supplies power to all the components in the computer.
CD-ROM Drive: There are two types of devices in a computer that use CDs: CD-ROM drive and a CD writer. The CD-ROM drive used for reading a CD. The CD writer drive can read and write a CD.
Floppy Disk: A floppy disk is a type of data storage that is composed of a disk of thin, flexible(“floppy”) magnetic storage medium encased in a square or rectangular plastic shell.
Internal Storage: Internal storage is hardware that keeps data inside the computer for later use and remains persistent even when the computer has no power.
Disk Array Controller: A disk array controller is a device which manage the physical disk drives and presents them to the computer as logical units.
On some computers the speakers are internal as well. :)
