Have you ever wanted to build your own super computer? Do you want to write programs that can run simultaneously on as many computing nodes as you wish? Do you want to learn what it takes to combine the processing powers of two, four, eight or more Raspberry Pis and run simulations at a fraction of the time and cost of running on a mainframe or even a high-end desktop computer?

If you've answered yes to any of these questions, then this course is for you. In this step-by-step series of video lectures, you'll learn how to set up your own computer cluster using cheap, affordable computers - and it doesn't get any more affordable than the Raspberry Pi.

Whether you're a Raspberry Pi enthusiast, a scientific researcher in need of cheap, expandable processing power, a programmer looking to expand their horizons with multithreaded algorithms, or a student looking to learn more about using Linux to build computing clusters, then you'll find plenty of value in this class as you build your own Raspberry Pi super computer.

These lectures are specially tailored to the Raspberry Pi 2 B+ board using Raspbian (a distribution based on Debian), which is a good place to start if you're unfamiliar with the Linux command line or building computer networks. If you are comfortable with the various flavors of Linux, you can use this course as a guideline for what it takes to build your own cluster using a different distribution.

Lastly, this class is a "living course", which means as we receive feedback and requests for specialized tutorials or updates, we'll continually update and add more to improve the quality and content of the course.

Students: 2938, Price: Free

In this course we will install Odoo 8 on a local machine (Host: Mac, Guest: Ubuntu 14.04 LTS). You can do that on Windows, Linux or Mac if you want. You just need Ubuntu 14.04 or a Operating System which can run Virtualbox (a free Virtualisation Software).

For all interested people in Odoo 8 this is a must have course to take. It's about a way in order to get odoo running on a local server. If you get this idea right, you can host Odoo on a local Server (let's say on your computer itself) or a server in your enterprise. Where this host will be is only limited to your infrastructure. The best thing is: you do not need to buy Odoo (SaaS) package and this installation is not limited to a specific amount of users or time range.

But we will not only install Odoo, we will install all the required software like:

- A virtualization software (VirtualBox) which is free

- The Linux Operating System Ubuntu 14.04 LTS (Long Term Support) which is also free.

A group of two or ore computing devices connected via a form of communications technology.

For example- A business might use a computer network connected via cables or the Internet in order to gain access to a common server or to share programs, files and other information

Data communications (DC) is the process of using computing and communication technologies to transfer data from one place to another, and vice versa.

It enables the movement of electronic or digital data between two or more nodes, regardless of geographical location, technological medium or data contents.

Data communications refers to the transmission of this digital data between two or more computers and a computer network or data network is a telecommunications network that allows computers to exchange data.

Data communications are the exchange of data between two devices using one or multiple forms of transmission medium.

The devices are in need to be a part of a communication system made up of hardware and software

Course Objectives:

1. Understand Computer Network &identify benefits of Computer Networks.

2.Understand and describe Communication Media.

3.Compare different types of Topology & network devices.

By learning the course students will be able to:

1: Analyze the functioning of Data Communication & Computer Network.

2: Select relevant Transmission media & switching techniques as per need.

3: Configure various networking devices.
