Lab – Using the Windows Calculator with Network Addresses Objectives Part 1: Access the Windows Calculator Part 2: Convert between Numbering Systems Part 3: Convert Host IPv4 Addresses and Subnet Masks into Binary Part 4: Determine the Number of Hosts in a Network Using Powers of 2 Part 5: Convert MAC Addresses and IPv6 Addresses to Binary Background / Scenario Network technicians use binary, decimal, and hexadecimal numbers when working with computers and networking devices. Microsoft provides a built-in Calculator application as part of the operating system. The Windows 7 version of Calculator includes a Standard view that can be used to perform basic arithmetic tasks such as addition, subtract, multiplication, and division. The Calculator application also has advanced programming, scientific, and statistical capabilities. In this lab, you will use the Windows 7 Calculator application Programmer view to convert between the binary, decimal, and hexadecimal number systems. You will also use the Scientific view powers function to determine the number of hosts that can be addressed based on the number of host bits available. Required Resources 1 PC (Windows 7 or 8) Note : If using an operating system other than Windows 7, the Calculator application views and functions available may vary from those shown in this lab. However, you should be able to perform the calculations. © 2018 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public. Page 1 of 7

Lab – Using the Windows Calculator with Network Addresses Part 1: Access the Windows Calculator In Part 1, you will become familiar with the Microsoft Windows built-in calculator application and view the available modes. Step 1: Click the Windows Start button and select All Programs. Step 2: Click the Accessories folder and select Calculator. Step 3: After Calculator opens, click the View menu. What are the four available modes? _______________________________________________________________________________________ Note : The Programmer and Scientific modes are used in this lab. Part 2: Convert between Numbering Systems In the Windows Calculator Programmer view, several number system modes are available: Hex (Hexadecimal or base 16), Dec (Decimal or base 10), Oct (Octal or base 8), and Bin (Binary or base 2). We are accustomed to using the decimal number system that uses the digits 0 to 9. The decimal numbering system is used in everyday life for all counting, money, and financial transactions. Computers and other electronic devices use the binary numbering system with only the digits 0 and 1 for data storage, data transmission and numerical calculations. All computer calculations are ultimately performed internally in binary (digital) form, regardless of how they are displayed. One disadvantage of binary numbers is that the binary number equivalent of a large decimal number can be quite long. This makes them difficult to read and write. One way to overcome this problem is to arrange binary numbers into groups of four as hexadecimal numbers. Hexadecimal numbers are base 16, and a combination of numbers from 0 to 9 and the letters A to F are used to represent the binary or decimal equivalent.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
