Question

Part 1 – Investigate simple cloud file storage.

Discussion:

Cloud services come in many shapes and sizes. For large corporates, outsourcing many services to cloud providers can be an effective but sometimes costly option. Fed University for example currently uses cloud providers for our corporate web site and also for Workstation management (controlling and updating staff and lab machine software). The university also has plans to use cloud providers for other IT systems.

At the other end of the spectrum is Cloud Storage Services which is primarily directed to the consumer market. These services provide free or subscription based access to internet (cloud) based storage and associated services. Products in this category include:

• Microsoft’s OneDrive
• Dropbox
• Google Drive
• Apple’s iCloud

Task 1 : Create some file for storing in the cloud.

Students who are working from lab machines can access their OneDrive storage from the 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

Create the following three document and save them in the cloud:

• A Microsoft work document
• An Microsoft Excel document
• A text file created with Notepad

Task 2: Access the file from your Linux Virtual Machine

Run Linux Lite.

Open a browser and login to OneDrive from the browser.

Note – Our Linux Lite Virtual Machines do not have Excel, Word or Notepad installed. Any editing of these documents will be done using the Cloud provider’s on-line applications.

Open the word document and make a few text and formatting changes.

Open the Excel document and do the same.

Open the Text document and make some changes.

Part 2 – Investigate the CDMA (Code division multiple access) protocol.

CDMA is used widely in mobile phone communications systems.

The aim of this digital protocol is to send the data from multiple devices as a single transmission therefore making better use of the radio channel bandwidth.

Each mobile device extracts its own data from the combined transmission.

To do this each user device is allocated a code that is combined with each bit of data to be sent.

The process involves combining many users’ data into the one transmission and then the extraction of the data at the mobile phone. To extract the data each mobile device uses its unique chipping code that was used to combine the data at the sender.

This process is demonstrated in the following YouTube video. Please examine it closely.

Then use the associated spreadsheet to replicate the YouTube video in paper format. This should give you a reasonable understanding of how CDMA works.

PLEASE PROVIDE EXPLANATION AND SCREEN SHORT OF EVERY TASK.

Answer 1

Part 1:

Task 1: Cloud file storage is a cloud service in which data is stored on remote server. And the data is maintained by a cloud service provider. When we store our files in cloud(through OneDrive), we can access and update files from anywhere on any devices.

One drive is owned by Microsoft, and is completely provide free services offering you 10 GB free. Here One drive provides Storage as a Service(SaaS).

Task 2:

In task 2, we access files through Linux Virtual Machine. And then open the browser and login to OneDrive cloud services and then access Word or Excel or Text document. But in our machine we don't have any Apps to open that document. In such case we can make use of Application as a Service from Cloud service provider. That is we can access and modify those files through cloud service(AaaS).
