Flashcard Content Overview

The set examines various hardware components of a computer system: the monitor, the CPU, the motherboard, desktop, laptop, keyboard, and graphic/video cards. The set also reviews the different types of computer memory: Random Access Memory (RAM), Read-only Memory (ROM) and Cache. Finally, the set examines ASCII, binary code, and the difference between a bit and a byte.

Graphics or video card
This card is used to process images so you can see them on your computer.
Optic Drive
These are read and written with a laser. You will see them on the front of a desktop unit. The most common ones in use today are the DVD (digital video disc) and the CD (compact disc).
Input Device
These devices are the way we're able to get data into a computer.
Output Devices
These devices are used to see and hear the data and information created and stored in your computer.
Monitor
Hardware created with LCD (liquid crystal display) or LED (light-emitting diode). Used to view the work, finished product, videos or photos, and anything else a computer can display.
Binary code
This code has eight bits that are strung together representing one character.
Cache Memory
The temporary memory where things you are working on sit for quick interpretation by the CPU.
Yottabyte
Equal to 1,208,925,819,614,629,174,706,176 (24 zeros) bytes!
DDR3RAM
The current consumer-purchasable version of RAM.
Bits
Binary digits that are either 0 or 1.
