CSP Flashcards
input
information is entered into a computer through clicking, touching, etc
output
the final form of the information that is displayed as images on the screen, sound, etc
processing
computer manipulates data; converts it into something it understands, like binary, through types like if/then, comparing, etc
computer
a machine that works with information
hard drive
- Storage space for all software (files, apps, programs, operation systems)
- Measured in Bytes
RAM (Random Access Memory)
- Temporary space for the CPU to work
- Like your desk top in class - what do I need right now to do the task at hand
- Measured in Byte
motherboard
- The main circuit of a computer
- All parts connect to it
- Allows communication between other parts of the computer
hardware
physical parts required for a computer to run; what makes a computer powerful
software
set of instructions that allows hardware to perform different tasks; can be changed; the ability to run different ___ is what makes a computer flexible
bit
a binary digit, represented by a 1 or 0
byte
8 bits together
convert from decimal-binary
subtract the number from the highest 2^ it can go; record a 1 for each 2^ it can be subtracted from
convert from binary-decimal
add the 2^ that are “on” (have a 1 in their place)
overflow
error from attempting to represent a number that is too large
rounding error
error from attempting to represent a number that is too precise; the value is rounded
ASCII table
standardized encoding system that assigns a decimal number to each text character that can be coverted into binary to represent them
abstraction
pulling away unnecessary information/details
pixel
a tiny, square, illuminated element that makes up a digital image, composed of one color
sampling frequency
how many pixels an analog image is split up into to represent a digital image
analog image
the real world image being sampled
digital image
representation of an analog image using sampling, pixels, and RGB colouring
RLE
form of losseless compression where each pixel’s contents are represented; color is listed first, then the number of subsequent pixels that are also that color
lossless compression
compressed down without a loss of data so it can be restored to its original quality
lossy compression
image data is reduced and lost forever; cannot be restored back to original quality
intellectual property
the instant theoretical rights/property a person gets to an idea
copyright
the exclusive legal right given to a creator to print, publish, perform, film, or record literary, artistic, or musical material, and to authorize others to do the same
Creative Commons
