the main idea of the paragraph is the theories of thye earth and how its changes over time1Explanation:
Universal is the correct answer.
Universal means something that is applicable in all cases, or can be shared by all people in general, which makes sense in the sentence since you are talking about something that is shared by a wide variety of people. As well, localized means a small group, archetypal means a certain type of person and current means now, none of these fit the description given. Therefore universal is the best choice.
Computer networks are physical (equipment) and logical (program, protocol) structures that allow two or more
computers to share their information with each other.
Imagine a computer by itself, without being connected to any other computer: This machine will only have access to
your information (present on your HDD) or information that may come to it via floppy disks and CDs.
When a computer is connected to a computer network, it can have access to the information that comes to it and the
information present on other computers connected to it on the same network, which allows much more information to
be accessed through that computer..
