Part 1: The Easy Part (01:30)
Familiar input and output devices, such as the keyboard and monitor, are known as peripherals.
Inside the Computer Case (04:54)
The main board, or motherboard, is home to a lot of the important parts inside of a computer. Explore the Central Processing Unit, or CPU, RAM, CD ROM, floppy and hard drives.
Ports for Input and Output Devices (01:53)
Serial, parallel, USB, and Firewire ports all have different uses depending on what is being plugged in.
How Does a Computer Really Work? (02:19)
Computer do three things: input, process input, and output. The keyboard, mouse, joystick, and CD drive are input devices, while the monitor, speakers, and printer are all output devices. The case with the CPU is the processing device.
Input and Output Devices (05:28)
CD's use binary coding to store information. Keyboards use chips to send information to the computer. The mouse uses a tracker ball and rollers to send information. All monitors are made up of pixels, dots on the screen made up of the primary colors.
Part 2: The Complex Part (04:52)
The hard disk drive stores information in a magnetic form. RAM, a grid of storage locations for data, has no moving parts and is much quicker to read than the hard drive.
The CPU (06:16)
The CPU is the brain of the computer. The CPU contains a circuit board containing millions of switches called transistors. Software uses binary code to tell the computer what to do.
The Clock (01:40)
The clock gives a pulse beat to the CPU to keep instructions in order and determine the speed at which the CPU carries out the instructions.
