I had an assignment where I had to create a web-based advertisement for a Computer that was created in the 1970 era or earlier. In my advertisement, I copied facts from Wikipedia such as "Output consisted of a row of lights", "The machine was programmed in pure machine code using an array of buttons and switches.", "The 8-bit machine offered 256 bytes of memory, implemented on Intel's type 1404 silicon gate MOS shift registers." And I cited my sources at the bottom of the site. Does this constitute plagiarism since I have copied facts and not opinions, and cited my sources?
