Objectives
• Investigate cloud file storage
• Investigate CDMA protocol

Part 1: Investigate Cloud File Storage
Cloud storage services areprimarily directed to consumer market. These services provide free or subscription-based access to cloud-based storage and associated services. Products in this category include
• Microsoft OneDrive
• Dropbox
• Google Drive
• Apple iCloud
Federation University students have access to Microsoft OneDrive.This service gives students and staff to access up to 1TB of cloud-based storage.OneDrive also allows access to online Microsoft Office applications, such as Word, Excel and others.To encourage consumers to use their products, cloud service providers add other services, such as file synchronisation to PCs, Macs, and Android devices.
Today, we will use OneDrive to store files from a Windows platform. We will then access those files from our Linux virtual machine, and then edit those files.Finally, the students will be able to accesscloud-based files from their mobile phones.

Task 1: Create aFile for Storing onCloud
Students who are working from lab machines can access their OneDrive storage from OneDrive icon in Windows explorer.If you are working from a machine without the OneDrive app you can:
• Install and configure OneDrive on your Windows machine OR
• Access OneDrive from a browser

i. To access OneDrive from a browser, or do a Google search for OneDrive for business login.
ii. Enter your Fed Uni email address and follow the prompts to authenticate.
iii. The OneDrive interface will open giving you 1 TB of cloud storage.
iv. Create the following three documents and save them on the cloud.
a. A Microsoft work document
b. A Microsoft Excel document
c. A text file created with Notepad
v. Each document should be named Topic8-lab-XYZ (where XYZ is excel, word or notepad).
vi. Each file should also include a line of text within the document (e.g.,Topic8 lab).

Task 2: Access the Files from your Linux Virtual Machine
i. Run Linux Lite.
ii. Open a browser and login to OneDrive from the browser.Note that the Linux Lite virtual machines do not have Excel, Word, or Notepad installed. The editing of documents will be done using the Cloud provider's online applications.
iii. Open the word document and make a few text and formatting changes.
iv. Open the excel document and do the same.
v. Open the text document and make some changes.

Part 1 Task
To gain one mark in this lab, demonstrate to your tutor that you can edit OneDrive Microsoft Office's applications form Linux Lite.

Part 2 - Investigate CDMA Protocol
Code Division Multiple Access (CDMA) is used widely in mobile phone communications systems.The aim of this protocol is to senddata from multiple devices as a single transmission unit to better use the radio channel bandwidth.Each mobile device extracts its own data from combined transmission unit.To do this, each user's device is allocated a code that is combined with bits of data to be sent.The CDMA process involves combining many users' data into one transmission unit andthe extraction of data on mobile phones. To extract the data, each device uses its unique chipping code that was used to combine the data on the sender side.This process is demonstrated in the following YouTube video, i.e., Please examine it closely. Use the associated spreadsheet to replicate the YouTube video in paper format. This should give you a reasonable understanding of how CDMA works.

Part 2 Task
To gain the second mark in this lab, demonstrate to your tutor that you have filled the spreadsheet and that you have a reasonable understanding of how CDMA works.
