A trademark is an easily recognizable symbol, phrase, or word that denotes a specific product. It legally differentiates a product or service from all others of its kind and recognizes the source company's ownership of the brand.
"Copyright" literally means the right to copy but has come to mean that body of exclusive rights granted by law to copyright owners for protection of their work. Copyright protection does not extend to any idea, procedure, process, system, title, principle, or discovery.
Fair use is a doctrine in United States law that permits limited use of copyrighted material without having to first acquire permission from the copyright holder.
Search engines - there was no single way to ask a question
The answer is spreadsheet. I just did this lesson and I got all of the answers right so I know it's correct.
If this is on personal opinion, I would say the initial creation of the telephone. Even though a smartphone practically kickstarted a whole era to technology that is still going on till this day, it was the telephone that started this all. If it wasn’t for the idea to create a phone that is more advanced than a box attached to the wall, none of these advancements would’ve happened at all. (Although that is uncertain, things do tend to have a way of working out in the end. If someone didn’t invent it, another person would’ve thought of it sooner or later.) But that is only if we’re talking long term, which I prefer because there was no limit to when the results of impact started in the prompt stated above, yet if we were to speak short term and the faster one, the credit would go to the smart cellphone. But we aren’t, because the question never specified ;)
Answer:
2^32 times as many values can be represented
Explanation:
32-bit. This means that the number is represented by 32 separate one’s and zero’s. 32 bits of 2 possible states = 2^32=4,294,967,296 possible values.
Integer meaning that only whole multiples of one are accepted.
Signed meaning that negative values are accepted. This halves the number of possible positive values (roughly), so the largest number you can represent is 2^31–1=2,147,483,647, but instead of 0, the smallest number you can represent is -2,147,483,648. An unsigned 32-bit integer, by contrast, can represent anything from 0 to 4,294,967,295.
