Intro to Computers
Information that a user physically enters into a computer by pressing a key on a keyboard, clicking a mouse, tapping a touch screen, pushing a button on a game controller, speaking into a microphone, etc.
What is Input?
A numbering system that uses ten digits, 0 through 9.
What is the Decimal System?
The part of a sound wave that is captured, measured, and assigned a numeric value during digital sound recording.
What is a Sample?
A system for making digital resources publicly available over the internet using a web browser that paved the way for email, chatrooms, and social media sites.
What is the World Wide Web?
"Nyeahh, what's up doc?"
Who is Bugs Bunny in Looney Tunes?
Information that a computer returns to a user such as images on a screen, sounds from speakers, and printed pages.
What is Output?
The smallest unit of digital information, represented by a 1 or 0.
What is a Bit?
A way of reducing the size of files, making them easier to store.
What is File Compression?
The speed at which a computer processes information, as measured by the number of cycles per second (Hertz) that the computer's CPU operates at. Measured in kilohertz, megahertz, and gigahertz.
What is Processor Speed?
"I'll be back."
Who is the Terminator in the movie Terminator?
The saving of information on memory chips, discs, or other storage media by a computer for later use.
What is Storage?
A group of eight bits joined together.
What is a Byte?
Images stored by dividing a picture into rows of pixels and collecting the color values of each pixel, in order, row-by-row.
What are Raster Images?
The measurement in bits per second that information is transferred through a network from one computer to another. Measured in Kbps (kilobits per second), Mbps (megabits per second), and Gbps (gigabits per second).
What is Throughput?
"Great Scott!"
Who is Doctor Emmitt Brown, in Back to the Future?
An electronic device that allowed entire computers to be built into a single board, replacing modules for each part of the computer.
What is a Microchip?
A physical signal, such as text, numbers, graphics, or sound, interpreted by converting it into binary numbers.
What is Digital Data?
A compression algorithm, such as GIF, PNG, PDF, and ZIP, that doesn't affect the original data. A file compressed using this, when decompressed, will be exactly the same as the file before compression, bit for bit.
What is Lossless Compression?
An international 16-bit encoding standard that accommodates character sets from multiple languages, with each letter, digit, or symbol being assigned a unique numeric value.
What is Unicode?
"That's a shame..."
Who is Jerry Seinfeld?
A smaller, faster, cheaper, and more durable electronic device that replaced mechanical relays, which were slow and tended to wear down over time.
What is a Transistor?
The most common format for text files in computers on the internet where each character is represented by a unique 7-bit binary code.
What is ASCII?
A common lossless compression algorithm that looks for repeated patterns of bits or bytes and records the pattern and then number of times the pattern is repeated.
What is Run-Length Encoding?
The amount of memory the computer uses to display colors in a digital image or a digital video. 8-bit color images use one byte of data for each pixel. 24-bit color uses three bytes for each pixel.
What is Color Depth?
"Adriaaaaannn! You Adrian! I did it!"
Who is Rocky Balboa from the movie Rocky II?
