Unit 3: Review

Binary System, Symbol, ASCII, Bit, Nibble, Byte, Kilobyte, Megabyte, Binary Position Value 1, 2, 4, etc. and Decimal Position 1, 10,100. 

Part 1

        During Unit 3 we learned a lot about the Binary System. The Binary System is basically 0’s and 1’s. And also the ‘language’ that computers use in order to function. We found out what Bit ( 0 or 1), Nibble (Four place value 1 0 1 0), Byte (eight place value 1 0 0 1 0 0 1 1), Kilobyte (A unit of memory or data equal to 1,024 (210) bytes.), and Megabyte (A unit of information equal to 220 bytes or, loosely, one million bytes.) is. We found what ASCII is. Basically ASCII is the American Standard Code for Information Interchange. ASCII encodes 127 specified characters into a byte (8 bits of binary). Symbols are called  bits not digits because dig refers to base 10.

Part 2:

We learned about what Algorithms are and what they are used for. Algorithms are a process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer. A linear search is basically an algorithm in which is a method for finding a particular value in a list that checks each element in sequence until the desired element is found or the list is exhausted. Binary search is more different because this search algorithm finds the position of a target value within a sorted array. 

Part 3:

We also learned what HTML is. HTML stands for Hyper Text Markup Language. The WWW (World Wide Web) is made of HTML. Document Object Model (DOM) is a programming API for HTML and XML documents. It defines the logical structure of documents. In order to create a webpage you need to know some of the tags you need to use like; <html>,<head>,<title></title>,<head>,<body>,</body>,</html>. Most html elements are written with a start tag, with an end tag, with the content in between.
