What's inside of a computer

Ipad/ Ipod

The iPad is a mobile computing device, but not a PC. Its interface works through screen gestures, not mouse clicks, and while it has Wi-Fi, it has no DVD slot or traditional USB ports. It excels at multimedia, has two built-in cameras and supports traditional Web and email.

Microphone

A loudspeaker, a transducer that turns an electrical signal into sound waves, is the functional opposite of a microphone. Since a conventional speaker is constructed much like a dynamic microphone(with a diaphragm, coil and magnet), speakers can actually work "in reverse" as microphones.

LCD Projector

LCD projector. An LCD projector is a type of video projector for displaying video, images or computer data on a screen or other flat surface. It is a modern equivalent of the slide projector or overhead projector.

Printer

Keyboard

A computer keyboard is an input device used to enter characters and functions into the computer system by pressing buttons, or keys. It is the primary device used to enter text. A keyboard typically contains keys for individual letters, numbers and special characters, as well as keys for specific functions.

DVD ROM drive

An optical disk drive (ODD) uses a laser light to read data from or write data to an optical disc. These include CDs, DVDs, and Blu-ray discs. This allows you to play music or watch movies using pre-recorded discs.

ROM

ROM stands for read-only memory. It's used to store the start-up instructions for a computer, also known as the firmware. Most modern computers use flash-based ROM. It is part of the BIOS chip, which is located on the motherboard.

GPU

CPU

CPU (pronounced as separate letters) is the abbreviation for central processing unit. Sometimes referred to simply as the central processor, but more commonly called processor, the CPU is the brains of the computer where most calculations take place.

Web Cam

A webcam is a video camera that feeds or streams its image in real time to or through a computer to a computer network. When "captured" by the computer, the video stream may be saved, viewed or sent on to other networks travelling through systems such as the internet, and e-mailed as an attachment.

Speakers

Regardless of their design, the purpose of speakers is to produce audio output that can be heard by the listener. Speakers are transducers that convert electromagnetic waves into sound waves. The speakers receive audio input from a device such as a computer or an audio receiver.

Monitor

A computer monitor is a display adapter that displays information processed by the computer's video card. ...Monitors have display functions that include powering it on and off, controlling brightness, contrast and position, among others.

Mouse

USB Memory Stick

About USB Memory Sticks – Universal Serial Bus. USB Flash Drives (also known as a memory stick or pen drive)A flash drive is a compact storage device that is used to transfer data between computers and other digital products.

Hard Drive

A hard disk drive (HDD), hard disk, hard drive or fixed disk is a data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material

RAM

RAM is considered volatile memory, which means that the stored information is lost when there is no power. So, RAM is used by the central processing unit (CPU) when a computer is running to store information that it needs to be used very quickly, but it does not store any information permanently.

Chip Sets

in a computer system, a chipset is a set of electronic components in an integrated circuit known as a "Data Flow Management System" that manages the data flow between the processor, memory and peripherals. It is usually found on the motherboard.
