Binary and Linear Searches

Write down a list of instructions for someone who is not in the class to tell them how to perform a linear and binary search.


Linear sort, this is when you sort through a list of ordered numbers until you find what you need.
Binary sort, this is wen you cut the list in half and the sort through the unordered nubers


Linear

-Look at people
-Ask for their names
-Compare to register item
-If a name isn't called but is on register, they aren't in


Mylist = (1,2,3,4,5,6,7)
i = 7
i - 1 until = 7


Binary
Mylist = (1,3,2,9,7,8,5)
i = 7
i - i/2
  if mylist is in i stop sort
  else ,loop

Networking

What are packets of data? They are units of data that travels to the destination using networks.
Why do we need packets of data? They make it easier to transport the data through the networks by changing it to binary.
