Picture This
100
A device that functions to gather, enter, and send data into the computer.
What is an input device?
100
A computer that processes information in digital form, usually binary code.
What is a digital computer?
100
A compact disc used as a read-only optical memory device for a computer system.
What is a CD-ROM?
100
A coding system using the binary digits 0 and 1 to represent a letter, digit, or other character in a computer or other electronic device.
What is Binary Code?
100
Is this an analog or digital device?
What is a digital device?
200
A device that functions to display and send data to a user.
What is an output device?
200
A computer that uses continuous physical magnitudes to represent quantiative information, like voltages or rotation of gears.
What is an analog computer?
200
Temporary or short term storage that can be reached quickly but is volatile which means it is gone when the computer turns off.
What is RAM (Random Access Memory)?
200
Short for binary digit, it is the smallest unit of data in a computer and has a single binary value, either 0 or 1.
What are bits?
200
Is this an analog or digital device?
What is an analog device?
300
A device that functions to store and save data and objects.
What is a data storage device?
300
A powerful computer with a high level of performance that can perform complex calculations on large amounts of data very quickly.
What is a supercomputer?
300
Permanent or long term storage that contains the programming needed to start a computer. Performs major input/output tasks and holds programs or software instructions.
What is ROM (Read Only Memory)?
300
A unit of data storage that consists of eight bits and is used to represent an alphanumeric character (letter, number, symbol).
What are bytes?
300
Is this an input, output, or storage device?
What is an input device?
400
A device that functions by connecting wirelessly to a network and transmitting data.
What is an IoT device?
400
A high performance computer with large amounts of storage and processing power, used for high-volume data processing. Supports many users and programs at the same time.
What is a mainframe?
400
A high-capacity, self-contained, electromechanical data storage device. Because it uses magnetic disks to record and store information, your data remains intact when the computer turns off.
What is a hard drive?
400
The unit which performs most of the processing and calculations inside a computer.
What is the CPU (Central Processing Unit)?
400
These are all examples of what?
What is a data storage device?
500

Inputs: keyboard, mouse, microphone, scanner, stylus, joystick, barcode reader
Outputs: monitor, speakers, headphones, projector, printer, 3D printer, copier
Data Storage: hard drive, external hard drive, CD, DVD, flash/jump drive, floppy disk, SD card
500
A microprocessor-based system belonging to a larger system, specially designed to perform a specific function.
What is an embedded computer?
500
A device that allows a computer to read from and write to computer disks.
What is a disk drive?
500
A printed circuit board containing the principal components of a computer or other device, with connectors into which other circuit boards can be slotted.
What is a motherboard?
500
This is one of the main components of a computer.
